White Series: Switch Freezing Occassionally

Switches General Discussion
,
1

I have 9 White Series dimmer switches installed and since installation I have now had 3 occurrences where 1 of the switches became completely unresponsive. Spread out over ~6 months.

  • Each time it was a different switch, so this doesn’t appear to be a single faulty piece
  • Switches were unresponsive to any inputs (Physical buttons, control through Home Assistant or Google). This included the factory reset inputs having no impact.
  • Switch returned to normal operation by cutting power at the breaker
  • Switches in question are configured as dimmers
  • I have HA routines which update some LED bars infrequently, but the impacted switches don’t correlate entirely with those routines.
  • Impacted switches were handling various different loads of led bulbs (3-5), nothing outstanding wattage wise that feels relevant.

Given the infrequency this has occurred, and generally easy resolution of flipping the breaker, I am not overly concerned as I otherwise have been absolutely thrilled with the product and will be installing at least another half dozen more I already purchased.

However it seems like there may be a firmware issue at play here that I am hoping my experiences might be able to assist in resolving.

I’ve had a similar situation, don’t need to flip breaker, just pull the air-gap and it resets, connects and is fine.

Completely unresponsive to any button presses.

I’ve had around 35 2-1 white series installed for 4 months now and the first two months I had ZERO issues.

Setup is with Home Assistant and the ZBT-1, With home assistant being the Thread Boarder (I have HomePods and appleTVs too, but setup with ZBT-1).

I have also been running into the issue lately with many switches around my house. I can also pull the air gap. Its seemingly random, but very frustrating. I have my switches set up in Apple Home and Alexa. I wonder if its an issue with being connected to multiple systems at once? For me its happening pretty frequently. Like once per switch every month? Definitely enough to be annoying.
