Hi Nick, when you say “2-way sync” I assume you mean HA knows when I turn off a light at the actual switch and the X-sig is updating HA of the change?
The way things work for me I can turn lights on and off via the UI and it updates the feedback on the UI perfectly, but if I go to the wall switch and turn off the light the UI feedback doesnt go low and HA still sees it as being on?
I can also use Alexa/Siri and turn lights on and off and it updates on the UI and I see the change when I turn them on and off but if I turn a light switch off then try to turn it back on with Alexa that doesn’t work because it. has the wrong state, so I have to say.
Alexa, Office light off, Alexa Office light on <—Say “Off” first because it still thinks its on
Basically I have to do this to get it back in sync 
I assumed if I turned a light off at the switch that the X-sig would pass the analog value to HA and it would know the light is actually off and other ingrations would also but mine isn’t working this way.
If this is the way its supposed to work when I am adding only analogs for each light from the X-Sigs?
Or do I need to use something else in my config file so HA knows I turned off at the switch? It seems my switches should be updating HA or the light.turn_on service somehow?
Thanks!
