I had an ESP8266 set up to toggle as a "Button Push" and a rule set up to toggle my lights on and off when it detected a button push. Today for some reason it no longer works and I'm not sure why. Now every time Hubitat sees a button push it will only turn the lights off... never on. Anyone seen anything like this?
Nope....never seen anything like that. Have you confirmed that you can still control the device from the edit device page? It sounds like it's a device problem, not a button problem.
I think you are right... I noticed that I changed the device type for one of the three bulbs I was controlling - and that fouled things up. My mistake!
