Yeah my project stopped just because of this same reason…
Prob is, that I’ve made MM on my rpi 3 and bought sonoff relays for turning on and off my tv, but the prob is, that when I power my tv it doesn’t start. It just gets its power and I need to use my remote for it. Now… if I would have some sort of remote app of some sort with wich I could control my tv, then this could be the answer (maybe some android remote or something)…
