Cool. I could probably simplify by just turning on "always turn on screen" in power amp and then one profile in taser that says when bluetooth is disconnected, turn "always turn on screen off" ?
I don't know how tasker works exactly so not sure if that's possible. But otherwise as you suggest will work.
Thank you. Hmm good point on safety. Actively playing probably yes. Connected to external power, normally i would say yes except i have a little device in between my tablet and power bank to keep it from going to sleep mode, which would probably defeat that.
I'll probably give tasker a go in the meantime.
