I’ve taken a bit of a different approach with these to get around the communication issue with the lights and it has been working flawlessly for me.
I swapped out my fan bulbs for smart bulbs. In my specific case I used the Globe WiFi bulbs from Costco flashed with ESPHome, but any smart bulb should work here. I went with these because they’re 4 bulbs for $19.99 CAD and could be flashed to ESPHome for local control. It was a proof of concept that I basically just kept.
Config for the switch I have the light itself turned ON, light brightness after power restored set to last state, and local protection set to light. This effectively locks the power to the bulbs always on and disables the button on the switch from being able to power them off. The light button on the switch still functions as a scene controller though which is important.
I then set an automation so that when a single click on the light button is detected, it toggles the smart bulbs. I’ve had this going for a few months now with 0 issues.
The 1 downside is you lose diming control from the switch itself. But you don’t want to dim power to smart bulbs anyways. The bulbs themselves can be dimmed through your hub. I handle dimming automatically with adaptive lighting so the lights get warmer and dimmer from sunset until their warmest/dimmest state at midnight.
