I have a White dimmer installed in a neutral configuration with one 4 way and one 3 way between the dimmer and the load. On 1.0.5 it worked as expected. After upgrading to 1.1.5 it behaves as though it cannot detect whether the load is connected or disconnected by the multiways downstream. For example, with the lights on, if I hit the paddle down on the dimmer, the lights transition down to 0 and the relay clicks off. The panel LED briefly goes dim to indicate the load is switched off, then the LED lights back up even though the load remains off. Hitting down again repeats this sequence except that the load turns back on (because dimmer toggles the travelers). Hitting paddle up has no effect because the dimmer thinks the load is always connected.
I’ve seen this behavior in a different circuit with another White on 1.0.5 firmware which had 4 multiways between the dimmer and the load. In this case I assumed there was just too much copper between the dimmer and the load for the dimmer to detect the state of the circuit. I remedied that by replacing the dumb switches with Aux’s, which worked fine.
I’ve tried factory resetting the dimmer, removed it and readded it to HA, and updated the configuration to Multi-way with Traditional Dumb Switches. Has anything changed in 1.1.5 that modified multiway load detection? Does anyone have any ideas that I might try to diagnose and fix this issue? Can I roll back to 1.0.5?
Thanks!
