Losing Ability to Control Some Switches

🛎️ Get Help
1

So, I got off a business trip and I noticed that Alexa (my primary mode of control) did not turn off my fan light but did not give an error. I discovered that I had lost all digital control. Here is what I tried:

  1. Alexa (Gives “Ok”; local web interface reflects change. Physical light does not change)
  2. Local Web interface (updates status on page and in log. Physical light does not change)
  3. Physical Switch (No update on the log or change in status; Physical light works fine)

I WAS able to recover the light. Here are some observations about that:

  1. I put Hubitat into Exclude mode and followed the sequence on the switch.
  2. Hubitat did not register the exclusion. I had to FORCE the removal
  3. I was initially unsuccessful getting the switch to reregister with Hubitat.
  4. Using a Aeotec Zwave stick next to the switch in Exclude mode, I was able to get the switch to exclude
  5. The switch registered without issue.

I now have 3 switches that “died”. I have brought 2 of them back, but will wait if it helps support debug (if they want).

My system: I have 90 devices including various sensors and switches. I have a mixture of zwave, zigbee, and hue.

The switches that “failed” are within 20 feet of the Hubitat hub; separated by a wall.

Any ideas?

Thanks

What is brand and model of these switches? I had similar issue with older GE non-Plus devices. Often turning off breaker for a few minutes got them working again vs exclude process. I ended up replacing them with Plus models.

It is a mixture of Zooz, GE and GE Plus. Strange thing is that I had no issue for a month and then lost three at once....

When you lose multiple at one it’s likely 1 switch that’s bad and the others were routing through this switch. You can try a repair to see if the others come online which will pinpoint the bad switch.

So I did the zwave repair. The one remaining “failed” device is a zwave toggle switch. The network id is 04 and it does not show in the repair logs. No other visible errors.

Thoughts?

So the other two started working again! For the bad device, I’d exclude and reinclude it. If it continues then the radio could be bad and you will need to replace it.
