I recently got a new watch-face for my Android Wear OS smartwatch. It's called Pujie Black and it allows you to add mini tap targets to the watch face that can be linked to Tasker actions (Tasker is an automation app for Android).
I made a few tasker actions that use the endpoints of Hubitat to initiate an action on Hubitat.
For example, hitting one button on the watchface unlocks the front door, one opens the garage door, one initiates my relax scene (sets all the lights in the common area to dim after dishes are done for the evening and we're just relaxing).
I'm wracking my brain trying to think of other actions that would be useful from a tap on my watch now!
