It’s been rock steady for many weeks now.
Only nit: sometimes, perhaps once every 10 days or so when I send a power off from my automation, my TV doesn’t turn off, but shows the ATV power menu up in the right corner and I have to press OK on the remote to power off.
Nice work! it was easy to setup and working like a charm, one thing i noticed. The AppName is not valid in my case.
It’s showing SkyShowtime (which is indeed installed) but currently i am running a different app on the apple TV, it seems not updating the field at all even when i am changing the running app. Can you confirm it also on your side?
