Devices offline, no fix in sight. Smartthings has acknowledged the bug

Quite a few of my devices were showing up as offline and I got the impression it was devices that I did not use very often. To liven them up again I just had to cancel out the offline message and then toggle the device or even just “refresh” it. None of the devices were actually dead so removing, adding or any drastic alternative was not necessary… This is very annoying so in the end I simply turned off “Device Health” in the app. The devices may still go “OFFLINE” but it doesn’t seem to affect things (or am I missing something??) so I will just wait it out hoping they will fix it. Is my issue the same as what is being discussed here or are your devices actually totally dead?

Through all this, I never realized until now that there even WAS a thing called “Device Health”. You would have imagine Smartthings support could have mentioned that. I turned if off, and the devices came back, at least in the app. Some of them don’t react to my commands, but at least I can try to repair the network, and play around a little more. Not a solution, but progress. Thanks Alex, and yes, that is the same issue.

Edit: While they don’t show “OFFLINE” anymore, the devices still don’t allow being controlled. The main difference is that now I can no longer easily see which devices are affected by the bug.

I found that if you turn off device health, devices show back up but they’re really not there. They just don’t show as not being connected.

Yeah, seems that way. I sure would love Smartthings to comment on this asap…

I have been hitting this bug with Water leak sensors or motion sensors (used as temperature sensors) in the ecoBeeSetTstatSchedule app.

When the sensor is used in the app as temperature sensor, it goes offline after 3~48 hours.
When the same sensors are not used in the app, they have been online for last 4 weeks.

Here is what I have observed:
2. I have 6 water sensors, here is the observed status:
a. Guest Bathroom Water Leak Sensor: Used by app , OFFLINE
b. Kitchen Fridge Water Leak Sensor: Not used by app, ONLINE
c. Kitchen Sink Water Leak Sensor: Not used by app, ONLINE
d. Laundry Room Water Leak Sensor: Used by app, OFFLINE
e. Master Bathroom Water Leak Sensor: Not used by app, ONLINE
f. Master Tub Water Leak Sensor: Used by app, OFFLINE
3. I have 8 motion sensors, here is the observed status:
a. Den Motion Sensor, Used by app, OFFLINE
b. Dinning Motion Sensor, Used by app, ONLINE
c. Hallway Motion Sensor, Not used by app, ONLINE
d. Kitchen Motion Sensor, Used by app, OFFLINE
e. Living Motion Sensor, Not used by app, ONLINE
f. Mud Room Motion Sensor, Not used by app, ONLINE
g. Stairs Motion Sensor, Not used by app, ONLINE
h. TV Room Motion Sensor, Used by app, OFFLINE

The following all describe similar issues occurring in the same time period, but I don’t know if they’re all exactly the same problem:

It was announced in the release notes for the version of both the android mobile app and the iOS mobile app that first included the device health feature. It’s pretty recent.

As far as I have noticed, all my devices reporting as OFFLINE actually work if I try to control them via the ST app. In fact when I was seeing the “Unavailable” error caused by the device health feature, all I would do was toggle the device or simply pres refresh. Given the devices never appeared to actually be dead, I turned “Device Health” off because it was not adding any value, if anything it was just annoying me.

I have had a few cases where a device just dropped dead but it was before the implementation of device health.

When you say your devices are just dead, have you tried to interact with them locally (toggle the switch) or pressing refresh on the ST app? Or are they failing to do something on a schedule or failing to be controlled by Alexa, or…?

I have the same problem with a GE 12727 Z-Wave switch… I uninstalled and reinstalled… Status still shows “Offline”, but it passes Z-Wave Repair and works as it should… Just robbed me of any chance of sanity and trashed a lot of time … lol

After some twitter messages to get Smartthings attention, they finally reached out to me again. Currently no solution, they are just asking me to remove/add the devices (which is a very painful process, that doesn’t really solve the WHY of the matter). I’ll let ya’ll know what happens, it could take a few days to figure out.

Edit: Two days later: I replied back with some followup questions and have yet to get a response. I am getting sorely disappointed with Smartthings support as the days wander by…

I found the same thing, The Device Health only reports as something being wrong because a device hasn’t reported in a specified time, I found this with my gun safe sensor which doesn’t change temp or any other activity very often, The device was actually functional regardless of what Device Health reported. I just think the formula they use to report problems need to be refined better.

I thought it was a problem with the Zigbee mesh as I did not have any powered devices. I went out and got a few Zigbee outlets to scatter around the house. Although not as many devices show unavailable now, I still get 2 or 3 per day. I’ve reset the device and usually that does it until the next time it goes unavailable, but it has been completely random and only my Zigbee battery devices.

I had the same problem a few weeks ago. Many of my sensors would show as offline randomly. I refreshed them individually and they would come back only to find the same would happen hours later.

Support checked and couldn’t find an issue so I reset my hub (removed batteries) and switched device health to Off. So far my problem has been resolved and all sensors appear to function correctly - recent firmware update may have helped too.

I removed my GE Fan Switch and added it back…again. It worked for about two days then became unavailable…again. I contacted Smartthings by phone and they wanted me to remove it and add it. I explained that if I do that it will work for a day or so then stop working. They said to send an email or use the chat feature for higher tech support. I then tried the chat and the rep said he can see it falling off and suggested I get the switch replaced. He said it is probably a bad switch… Ugh. Guess I can try that.

I’ve also encountered this within the last 2 weeks. Spent hours today trying to fix it - not fun. I do hope ST fixes it soon.

This problem has been going for pretty long now.
My setup is really useless right now, nothing is working…
Unreal how you can have everything working and stable and they do their updates and nothing works.

If the device shows unavialble, but actually still works. Which is how mine have all been. Either turn off device health in app, or setup pollster to poll the device ever so often and problem is solved.

Do you have Pollster or any other smartapp that calls Refresh often in the devices that go offline?

My hub (and all connected devices) has been intermittently “Offline” over the last couple of weeks.

I literally cringe when SmartThings announces that it will be “upgrading” its firmware or mobile app. I can’t think of any other major (or even midlevel) tech company that consistently releases such buggy software.

In my case, the devices that go offline are always query for Refresh too often, almost every minute:

Here are the details from some of them:
Guest Bathroom: 8:12 pm, 8:10pm, 8:07pm, 8:07pm, 8:06pm, 8:06 pm, 8:05pm, 8:03 pm, 8:00pm, 7:55 pm, 7:55 pm
Kitchen Sensor: 8:12 pm, 8:10pm, 8:07pm, 8:07pm, 8:06pm, 8:06 pm, 8:05pm, 8:03pm, 8:00pm, 7:55 pm, 7:55 pm

And the same for any other device that is offline and used as temp sensor in ecobeeSetZoneWithSchedule
