Bugs from a Specific Platform/Hub Update

September 2016

Hotfix September 20, 2016: multiple bugs [1]

platform update: major lag processing sensors [2]

platform update: various mode change issues [3]

Sept. 30: all scheduled tasks failing including mode changes [4]

October 2016

Multiple new reports of schedules failing and routines timing out [5]

November 2016

November 10 platform update broke the ability to change arm/disarm state in SHM for about half a day after the update completed. This was then repaired. [6]

November 10 platform update broke the ability for third-party apps to communicate with SmartThings, instead redirecting the page to the SmartThings IDE. This impacted smarttiles, google home, IFTTT, Harmony, and other services using OAUTH. This was repaired a few hours later . [7]

November 17 hub update failed for about 10% of the first set of customers, causing their zigbee devices to then be unreachable. ST halted the rollout of updates and is working on a fix for the affected customers. [8]

December 2016

December 1 update caused some initial problems, listed on the official status page. Although these were supposed to be fixed by the afternoon, multiple community members continue to report problems, particularly with zigbee devices and not being able to add new zigbee devices. It's not clear why some members are affected while others are not. Make sure you report the problem to support if you do have the issue. [/ Community discussion] Update: Smartthings staff have now confirmed that some customers were affected by multiple zigbee issues after this update. These include Motion sensors continually sending false alerts. [Staff confirmation]. Continue to report the problems to support if you have them.

March 2017

Hub firmware was updated to 17.11 in a rolling release that affected a few hundred customers at a time. One community member reported that their devices started failing and they got repeated "hub update" and "zwdebug" messages in the log. Support is investigating. [community discussion] on March 22, the rollout was halted because multiple customers reported that the update failed, leaving the hub with blinking red or magenta lights for hours and the system inoperable. [discussion thread]

April 2017

Hub firmware was updated to 17.12 in a rolling release. Several community members reported that after the update completed, they lost control of zigbee devices, particularly Osram and Wemo lightbulbs. This appears to be because the hub was off-line for long enough that the bulbs reverted to the ZLL profile instead of the ZHA. Resetting the individual bulbs and then re-adding them to the smart things hub should solve the problem. [Staff discussion]

Some Community members report system delays since the new firmware was applied. [community discussion]

May 2017

After a hub firmware update, some community members began having problems with Z wave devices where the manufacturer field would be set to all zeros and the device would no longer respond. This seem to particularly affect Yale locks, but other zwave devices were affected as well. In June 2017, SmartThings engineering staff said that a fix had been found and would be applied in a future update. Meanwhile, some community members have reported that they have been able to get the device to work if they just keep excluding it and re-adding it to the network until eventually they get valid entries. See the [community discussion].

Mobile App Bugs

September 2016

All 3 mobile apps were updated: multiple bugs including not being able to find smart apps, frequent log outs, modes not working, widgets not working, routines not working, not being able to view video in smart home monitor [9]

Can't find list of smartapps [10]

October 2016

Mobile app very slow [11] Staff responses in the following thread [12]

Can't log in. Confirmed by ST staff as a backend problem affecting all OSs. [13]

November 2016

Windows app frequently logs out [14]

Problems with mobile presence detection, particularly in the UK, but also some reports from the US [15]

Android app update 2.2.2 results in an error when trying to save a new Automation from multiple smartapps, including SmartLighting, Core, and Lock Manager. (The IOS version does not have the same bug.). The bug was fixed later in the day. [16]

December 2016

A mode change will occur as scheduled, but the mobile app will continue to show the previous mode until there is a hard refresh. [Community discussion]

February 2017

February 11: [mobile app just spins, can't log in]. This appears to only be affecting some customers. Staff has reported that the error was caused by the contact book timing out for some customers, and a fix has been applied.

March 2017

Colors changed on some of the icons on the things screen, so that some are blue and some are green. It turns out this is part of a change for some device type handlers, and for whatever reason it is being rolled out a little at a time. [community discussion with confirmation from support]

Some icons no longer respond to presses in the android app. This is a confirmed bug. There is a workaround if you are willing to change some code in the DTH. Definitely report this to support if you are affected. [Community discussion detailing the workaround].

May 2017

-IOS Mobile App Update 2.3.5: multiple users reporting that smartapps will not load. Community discussion. SmartThings staff have now reported that the problem has been identified and will be fixed in a future update.

-Android Mobile App Update 2.3.5 and 2.3.6: multiple users reporting crashes and that the app is running their phone's battery down very quickly. community discussion Staff have posted that a 2.3.7 release is expected shortly to correct the battery drain problem, but it may not correct all of the other problems that have been reported so far.

- some members reporting that after the recent app update, mobile presence no longer works the same way with multiple locations. Community discussion Reportedly fixed with update 2.3.6

- some U.K. members reporting problems with the Android app. community discussion

June 2017

- multiple people reporting that they are unable to save favorites in the new version of the app. If you have this problem, contact support. [Community discussion]

- SmartThings engineering staff is asking for help in investigating an issue were some people are reporting that they are frequently getting logged out of the iOS mobile app. If you are having this problem please report it in the format requested in the [community thread]

General Platform Bugs including Mode Changes Failing, Database Corruption, IDE problems and Mysterious Events (Also see the Smartapps Section and the Platform Updates Section)

September 2016

because of the hub and platform updates this month, problems were reported as related to the update. See the platform update section for this month.

October 2016

Garage door opening and closing randomly [17]

IDE errors and severe lag ( according to ST staff this is related to the other lag and time out issues, it's not just the IDE) [18]

Mode changed mysteriously to morning in the middle of the night [19]

GITHUB format changed, can't find code [20]

Lights turning on when they were not scheduled to at the same time several days in a row [21]

Mobile app asked for authentication code, then appears to have completely reset. (Staff suggests it may just have created a new location.) [22]

November 2016

Daylight savings time fail [23]

Multiple problems reported related to the November 10 platform update. See that section above.

November 12: multiple people writing that device reports, particularly from sensors, aren't being processed. Many automation failures even though the devices show as active.. [24]

November 24: Device control and scheduling failures affecting customers on the NA01 shard. Smartthings engineering is aware of it and is working on a fix. Some customers still reporting problems on Friday morning. [25]

December 2016

December 10: Major cloud outage [official status page]

December 22: Multiple community members, but not all, reporting that routines scheduled to run at sunset never fire. The current workaround is to change the rule to run at a specific time. [community discussion]

December 27: multiple strange problems with people either unable to login or having missing devices or even a missing hub from their account. Support is aware of the problem and there have been on and off notices on the status page. [community discussion]

February 2017

February 2: [system outage]

February 28: Amazon Web Services outage is affecting cloud services all over the world, including a number of SmartThings services, as well as some IFTTT and harmony services. [Community discussion]. Amazon says they have identified the problem and have a fix, with some websites beginning to come back around 6 PM Eastern. [USA Today on the outage]. SmartThings returned for most community members around 7 PM Eastern.

March 2017

Mysterious network pings causing random events, including [garage door opening unexpectedly]. [another garage door] It's unknown if these events were related to the recent hub update or not. Report it to support if it happens to you.

March 11: random instability, bad enough to be reported on the official status page. The status page says the problem was resolved after a few hours, but some community members are reporting that they are still having problems with sensors [community discussion]

March 27: multiple members report everything has gone dead. After an hour or so, it came back intermittently. This was reported as resolved in a few hours. [community discussion]

April 2017

-Some members reporting random events, lights turning on unexpectedly, Core routines not running, etc [community discussion]

-April 13 Major outage: Loss of cloud operations with random results: some devices not working, some turning on unexpectedly, some automations delayed for 10 minutes or more. Outages appeared random and intermittent, making it difficult to troubleshoot, but the issues appear to be on the cloud side. [official status page] [community discussion] The company reported that the outage was resolved early afternoon on the 14th, but some customers continue to have issues.

-( this issue may have begun in March, it's not clear) multiple members reporting multiple devices show as "off-line" and then have unpredictable results. Some can still be controlled with echo but not from the app. Some failed to function in routines and other automations. Just a lot of variation. Both Z wave and zigbee devices have been reported as affected. At this point support has acknowledged a known problem, but no workaround as yet. Some members report that if they turn health check off through the IDE and then turn it back on the devices will be OK again for a little while. It does seem to have some relation to the new healthcheck feature but, again, no work around yet. [community discussion]

-On April 20, A platform change was made which introduced a bug into the way that some device responses were handled. This affected many different device type handlers. In some cases, such as thermostats, certain features stopped working like the ability to change mode. In other cases, devices were marked as off-line which were not. The problem was identified by community developers and smart thing staff were able to apply a fix on April 25, although some member say they are still having problems. This appears to be different then the problem which was reported earlier in the month of devices just being marked off line. [community discussion in the developer section of the forum]

May 2017

-Ongoing intermittent delays where commands can take several minutes to execute. This problem was first reported by some members in April, but by May there were multiple reports involving both zigbee and zwave devices. The problem comes and goes, and sometimes affects different devices, making it difficult to diagnose. Rebooting the hub appears to fix the problem for a few hours, but then it will return. Support has not yet acknowledged the issue, but is treating each individual report as a local interference problem. If you are affected, definitely put in a support ticket. [Community discussion]

-May8: some members reporting that they are getting error messages when using the IDE. Community discussion

-May 10: weird new login screen for the IDE. This one isn't a bug, it's just an unannounced change. Since some people now have Samsung IDs. rather than just SmartThings IDs, The new login screen sorts that all out. Staff have posted an explanation in the Community discussion thread.

June 2017

-About a dozen different community members are reporting strange new reliability issues in June, particularly extensive delays between a trigger event and a routine or automation firing. Also problems with device is becoming unavailable and strange zwave messages. These were all things that were working fine in May where multiple problems appear at once. It's not clear whether any of these reports are related to each other. It's always possible could be individual hub failures and it's just that as the number of customers increases there are occasional individual failures. No staff comment yet. Anyone having these problems should begin by reporting it to support. It may also be helpful to turn off device health, but that doesn't help everyone. [Community discussion]

- June 17, System outage affecting some customers. Acknowledged on the official status page. [community discussion]

- Multiple forum members reporting that devices which used to be just fine are now reporting "off-line" frequently. [Community discussion]

SmartApp and Routine Bugs

September 2016

Core: [26]

Time-based routines failing [27]

Mode changes but then nothing triggered by the mode change runs [28]

Voice notifications sometimes missed or only plays partial, multiple smartapps [29]

October 2016

Core Pistons executing randomly [30]

Scheduled apps failing [31]

November 2016

SHM screen stuck on "loading" for hours, cannot arm or disarm smart home monitor. Affecting both iOS and Android. [32]

January 2017

Multiple people reporting either security error messages or timeout messages when using either the IDE or the mobile app. Engineering staff have confirmed that this is an issue with one of the databases. It is not related to any specific smartapp, including core. It is only affecting some customers. [staff discussion]

SmartThings made a platform change for security reasons which broke several smartapps that display camera images. Note that this is different from The problems with blink cameras that occurred about the same time. [Community discussion]

February 2017

Multiple people reporting that some Core Pistons are failing, but routines are working. [community discussion]. In Some cases, the problem appears to fix itself after an hour or so.

May 2017

-something changed in the way that smart things allows for third-party authorization, and consequently some third-party apps are no longer able to connect with SmartThings. This includes smartrules and beaconthings. The developers are working with smartthings to try to find a solution. community discussion

Smart Home Monitor

September 2016

Video clips only playing if downloaded [33]

October 2016

Video clips not playing [34]

November 2016

SHM screen stuck on "loading" for hours, cannot arm or disarm smart home monitor. Affecting both iOS and Android. [35]

December 2016

Speech notifications not working with some SHM alerts. After investigation by SmartThings staff, two separate bugs were identified, and a fix has been promised soon. [community discussion]

April 2017

Smart home monitor not loading. Reported on [the official status page].

April 7: Some members report that if a sensor is included in armed/away but not in armed/Home and they have the paid scout monitoring that if the sensor detects motion in armed/home, Scout will consider it an intrusion alert even though SmartThings doesn't. Support is looking into it. There is a workaround using core and a virtual motion sensor, but that will not work if the Internet is out. [Community discussion]

May 2017

Smart Home Monitor problems, including being unable to dismissed. This is been reported on the official status page. It was reported as resolved a few hours later.


December 2016

SmartLighting has changed and now if you try to create a new automation there is no way to specify the button number that you want to use on a minimote with the stock device Handler. Any other device type handler which does not specify the number of buttons field will have the same problem. [36]. Update: this was fixed in the minimote device type handler on 6 December 2016.

February 2017

Multiple people reporting that local SmartLighting automations are failing, but routines and. Cloud-based versions of the same SmartLighting automations are working. [community discussion]

May 2017

-May 16: Multiple problems being reported. This may be related to the smart home monitor problem which has been reported on the official status page. It was reported as resolved a few hours later.

By Device/Integration

September 2016

severe lag for Hue bridge [37]

Hue bridge has a bad address or some bulbs unreachable from ST ( but work OK from other apps) [38]

Hue bulbs marked as "unreachable" still work through the Hue app but don't work through SmartThings [39]

Samsung SmartThings motion sensor false positives [40]

Samsung Smartthings multisensor false positives [41]

LIFX wonky [42]

Samsung powerbot vacuum not working [43]

October 2016

Arlo clips not displaying [44]

GE/Jasco in wall switch indicator lights suddenly change behavior [45]

Multiple Hue problems, including severe lag[46]

Friends of Hue (bloom, strip) and the old Hue Lux that used to work with smart apps now don't seem to respond to smart things, although they continue to work from the native hue app [47]

SmartThings sensors keep dropping off network, or only report temperature, or battery reporting incorrect [48] (includes ST staff comments)

Sonos plays once or twice, then stops, or fails altogether [49]

Sonos stutters [50]

November 2016

November 12: multiple people writing that device reports, particularly from sensors, aren't being processed. Many automation failures even though the devices show as active. [51]

Hue bulbs showing significant delay between bulbs when a group request is processed through SmartThings, creating a popcorn effect. Reported as new in the last few weeks. [52]

Samsung smart vacuum won't connect to SmartThings even though it works fine with the Samsung smarthome app. [53]

Two people reporting that they would create a simulated switch on one day, everything would work fine, and the next day the simulated switch would have disappeared from their account. [54]

December 2016

Smartthings did a zigbee firmware update in early December to allow over the year (OTA) updates of the SmartThings branded devices. Since then, multiple community members have reported that when the OTA check occurs every day, their Osram RGBW devices do strange things, generally reverting to white and coming on full brightness. Other community members are not having a problem with these devices, so it may depend on the firmware level of the Osram device. If it happens, report it to support. [Community discussion]

The same zigbee update is causing some zigbee motion sensors to think they are supposed to be updating when they are not, and issue multiple false motion alerts, sometimes over many hours. So far this has affected both the Samsung brand motion sensors and the hue motion sensors which are connected directly to the smartthings hub. [community discussion]

Around December 15, multiple community members begin reporting that they were having odd device communication failures, and that those failures could affect devices of any protocol. The devices appear to be reporting in OK, but instructions to the devices were sometimes logged but not performed. Both Z wave and zigbee devices could be affected. Rebooting the hub might cause things to be OK for a few hours or a day or so, but then the problem would return. Support is currently collecting all reports of this issue. It is definitely not affecting all customers, but it is affecting some, and both V1 and V2 hubs have been affected. [Community discussion, including the support ticket number you should reference when reporting this problem]

January 2017

Some members report GE switches randomly changing parameters, particularly for when the indicator LED comes on. This might represent back end changes. [community discussion]

V2 Hub batteries Many community report leaking batteries in V2 hubs. After investigation, SmartThings determined a firmware update was needed and this was distributed on 30 January 2017. [Community discussion]

Blink Cameras found that some server outages on their side were being caused by excessive polling from outside services, including SmartThings, and they decided to cut off this integration option. After discussion with RBoy , who makes a paid smartapp that was developed in consultation with Blink, they decided to allow one version of his smartapp to continue to have access temporarily while they try to find a long-term solution. The other smartapps will not work. [community discussion]

Alexa As of January 30, a few community members have reported that Echo commands that previously worked are no longer working. In most cases, this was a situation where the person had more than one SmartThings location, and somehow Echo appeared to have switched to a different one. Details are not clear yet. [community discussion]

February 2017

Color bulbs are coming on at a different color than they used to, particularly shades of white. Smartthings staff explained that in order to try to synchronize different brands of bulbs, such as LIFX and Osram, they have changed the way color temperature is set. So new defaults are now being used. If a customer had previously individually customized color temperature on a bulb in order to attempt their own synchronization, they might now be seeing unusual results. [Staff explanation of the new defaults]

Alexa Several community members have reported that in the last week or so they are starting to see multiple log entries for Alexa but the devices don't change state, it's just some kind of polling or something. No official response yet. [community discussion]

IFTTT authorization fails. This problem appears to have been corrected on March 1. If you're still having problems, contact support. [community discussion]

Google Home processing a first home automation request, but then replying "something went wrong" for any further requests. Google support has confirmed that it is a problem on their side and they are looking into it. [community discussion]

March 2017

GE Switches using the Stock DTH' suddenly reverse the behavior of the LED indicator, so that it is off where it used to be on. This is probably the same issue that occurred in January, where a backend change was made that introduced this error. If you are affected, report it to support. [community discussion]

LAN Devices like Hue and Sonos suddenly showing up on the things list when they weren't there before. This is a change having to do with the rollout of LAN Connect. There is now an automatic discovery of any devices on the same local network as the hub and the devices are added automatically, you cannot opt out of it. You can go back in and remove them individually, but they will be re-added every time you run a "add a new device" for any device of any protocol. Official position is that this is a new feature, not a bug. [Community discussion]

WiFi Devices like WeMo and Ihome frequently using losing contact or failing to update status. Multiple people reporting this in the forums in early March. It's not clear whether this is related to the LAN Connect change, to the new wellness check, to the new versions of the mobile app, or something else altogether, but it is affecting multiple people. If you are affected, report it to support. [community discussion on WeMo]

All zigbee Devices lost connection could be just a coincidence, but two different community members reported that all of their zigbee devices dropped off line about the same time. If you have this problem definitely report it to support. [community discussion]

Zwave Plus Devices not updating status. This is been reported for both the new GE switches and the new Leviton switches. [community discussion]

UK SmartThings socket overheats. This applies only to the UK version of this device. Several community members reporting that plugs don't quite fit in the socket and this can lead to a fusing problem. [Community discussion]

April 2017

First Alert Z Combo Smoke Alarm After the April hub firmware update, multiple community members have reported some false alarms from these devices, in some cases more than a day after the update completed. If you have this problem, contact support. [community discussion]

Google Home integration not working. [community discussion]

Horstman Z-Wave Thermostat reported by multiple members as previously working and suddenly showing strange behavior around April 19. The device except the set command but then nothing ever happens. [community discussion]

Honeywell Thermostat reported by multiple members as previously working and suddenly showing strange behavior around April 19. This may be the same problem that is affecting the Horstman Thermostat. [community discussion]. If you are affected by any of these problems, contact support.

Multi endpoint zwave Devices no longer working again, the devices were previously working well. [community discussion]

June 2017

IFTTT Maker Option IFTTT introduced a new maker option for people who want to create applets for others to use. Multiple reports from the community that the IFTTT site would not allow a SmartThings device to be added to an applet through this option. One community member reports it does work if you Are using the IFTTT mobile app instead. [community discussion]

Lutron Caseta Devices The initial integration works fine. However, after that, if you try to add one more Lutron device it just won't add. If you have this problem, report it to support. [Community discussion]

ISP5 Plugs that previously worked fine now go off-line to smartthings multiple times a day, but still work fine with HomeKit or their own app . [community discussion]

Arlo Cameras interfering with routines. Community members report that support says this is a known problem. [Community discussion] July 1: Smartthings staff say that cause has been found and a fix should be deployed soon. [55]

Bugs reported by developers regarding the ST groovy implementation

September 2016

"Ghost" routines (null label) [56]

December 2016

HubAction calls crashing hub [community discussion]

March 2017

GitHub integration seems to have reset, all links missing. If you have this problem, contact support, as they are investigating. [community discussion]

April 2017

-Existing device type handlers showing a change in behavior, including configure no longer working. [community discussion]

-Reported beginning April 20. Response() not being processed correctly, Breaking existing device type handlers and some smart apps. Staff investigated and found a bug. A hot fix was applied on April 25, but some community members report still having problems. [community discussion]

May 2017

-Android 2.3.5 update breaks sorting. Not strictly a groovy issue, but it is affecting developers. Sort levels are being forced on the UI, and ignoring the Enum value set by the developer. So days of the week are being displayed in alphabetical order. Numbers are being grouped so that the display is "1 hour, 1 minute, 2 hours, 2 minutes" rather than the developer's intended sort of "1 minute, 2 minutes, 1 hour, 2 hours." Etc. discussion in the announcement thread of the new release Fixed after a few hours.
