I have a red inovelli switch (not dimmer) set up in a three way like so:
I’ve triple checked to make sure everything looks right. When I turn off the dumb toggle switch at the other end the light turns off. If I turn the switch back on immediately it is fine, but if I wait a few seconds I eventually hear the inovelli ‘click’ off at the first location. If I then try to turn the dumb switch on nothing happens.
If the dumb switch is off, and a I try to turn on the inovelli switch it clicks on and immediately clicks off.
I’ve tried looking to see if I need to set the red switch to three way mode, but I don’t see anything in the manual about a three way parameter to change to (where it is pretty clear with the dimmer)
I’m using home assistant.
Any ideas? Should I quadruple check my wiring?
