I mostly just wanted to say that this is an amazing tutorial, and thank you so much! Your very detailed and helpful video guide walked me (a relative newbie) through the process perfectly!
I did have one question - it seems to me that having the device state change trigger the input_boolean toggle, which in turn triggers the REST action, is adding extra steps? Why not just have an automation that triggers on device state change, and the action is the REST action right off the bat? Is it something to do with what’s (not) possible in the automation configuration?
