Z-Wave Devices going offline

Starting last week, every few hours around 7-10 z-wave devices are going offline. If I reboot the hub through the IDE they come back online. I have tried several z-wave repairs, that all fail on multiple devices. It seems to affect all types of devices - GE Light switches, gocontrol garage door controllers, aeotek multi-sensors, and Schlage door locks.

I am beginning to think that I have a hub that is going bad. Any thoughts?

I have not heard back from support since Sunday - but I have left the hub running and not rebooted it. The same 11 devices go offline and then a few hours later come back on their own and then go back offline for a few hours.

Interesting, which firmware is hub running?

Also, some random things to check:

  1. is it on a power strip? If so test with direct to wall recept, could be malfunctioning surge protector
  2. how hot is it (the hub), does it have adequate ventilation?
  3. have you checked the IDE logs for possible issues? You might have to let the logs run for awhile to catch that random zwave failure
  4. any webcore pistons acting up and making too many requests or smart apps?
  5. Is your hub going offline (home router)?
  6. have you tried taking out the backup battery in the hub when you reboot?

If all these check out it’s possible the hub might be need to be replaced :frowning:

How do I check my Hub’s firmware version?

From the SmartThings mobile app:

  1. From the Home screen, select Menu (Menu icon) and touch Devices
  2. Select the Hub
  3. Select More Options (More Options icon) and touch Information
  4. Check the Firmware Version field

From the SmartThings Classic app:

  1. Tap the menu (Android) / More (iOS)
  2. Tap the Hub
  3. Check the Firmware Version field

You can also check your Hub’s firmware version through the SmartThings web console:

  1. Go to the SmartThings IDE
  2. Log in using the email and password for your SmartThings account
  3. Click My Hubs
  4. Check the Firmware Version field

What is the latest firmware version?

Sounds like you might have a weak mesh or bad/overloaded repeater.

Have you added or removed any devices recently?
When the devices show “offline”, are you still able to control them (or see sensor reports from them)?

Matt - I have tried all of those, and the hub doesn’t go offline, and the devices cannot be controlled. My hub firmware is 000.026.00012.

Tony - I haven’t removed anything, but you did make me think… I did add an Aeotec whole house energy meter that reports tons of data. I wonder if this unit isn’t overwhelming the hub, especially since this problem is cyclical and the devices go offline and back online everyday. I am turning off the reporting and going to see what happens. I will post back my results.

Thanks for the help.

Well this morning I disconnected the Whole house energy meter and that seems to have fixed the issues. Went all day with nothing offline.

Thanks for the help.
