I have a few Blue 2-1 switches I’ve set up as virtual 3-way configurations using the Zigbee binding app on Hubitat. The on/off functionality always works, but I’ve recently noticed several times where the light is off, but one of the switches (the remote one) has the LEDs set to the previous lighting level.
If I click on or off from either switch, they get back into sync for a while and then a day or so later I will find one or more of my Blue switches out of sync with it’s 3-way partner.
Is the mechanism the Zigbee Binding app users different than the binding tools in the driver itself? Does the built-in driver binding even work? I’ve noticed even though the switches are bound using the tool, the binding count in the settings page for those switches shows 0 for number of bindings.
