I have a GE Z-Wave paddle switch connected to ST that I’d like to exclude from any all on or off commands. I read something about it and I think I should be able to do it, but can’t find any specifics on how. Ultimately I’d like to be able to tell Google Home something like turn everything on or off, and only that 1 switch would ignore the command.
First thing that comes to mind is to just create a group for your lights. Either in ST or Google Home (not sure if this is supported, I’m an echo user).
The easiest way to do this with GH is to use IFTTT. First, create a routine in ST, excluding the switch. Then, create a recipe with Google Assistant and SmartThings and when you say a specific phrase, run the ST routine.
It’s not pretty, but GH is pretty limited in what it can do natively in ST. You might be able to do it with webCoRE or Stringify, but I’m not 100% certain.
There is an app called Google Home Helper that will allow you to trigger a routine using a virtual switch.
