I recently took out a Zen32 and replaced it with a Zen35.
Previously it was a 3-way, and I of course rewired the remote dumb switch.
What’s happening is SOMETIMES the remote switch needs to be toggled twice to either turn the light on or off. I hear no click from the 35’s relay on the first flip.
Trying to quantify it, it seems that if I turn it on and pause a few seconds, then it needs to be toggled twice to turn off. And same for off to on.
I can stand there and rapidly toggle it on and off reliably. Weird.
I’ve got the 3-way switch type set to Toggle. Integration is with Home Assistant.
Ramp on and off are set to instant.
The Zen35 works correctly, and turns the light on and off no matter what the position of the dumb switch is.
