Home Assistant advice - how to automatically switch off a dumb TV?

[Whiffle]

Hi there.

I have a Zigbee-based set up, running off a Pi.

I have this really irritating issue, involving three of my TVs (all non-smart and non-CEC).

They each have a Firestick attached to them, which turns the screen to black after 5 minutes.

My family keep thinking that the TV is off and thus the TV is left on for hours at a time - not particularly good, given the energy crisis.

I cannot think of a way of getting HA to automate this.

There is a Firestick integration (Android TV) that can sense when a Firestick is idle - I could then use this to tell a Zigbee IR blaster to then turn the TV off (and then on again, should the Firestick state change to anything but idle.

HOWEVER - I realised that this is far from fool proof - i.e. if the IR blaster fails to turn off the TV, one time, the whole system will become backward.

I cannot think how to get round this and would appreciate any advice.

Thanks very much.

Won't killing the power, to a TV that is on, potentially damage it?

Thanks for that - that being the case, a Smart switch would be perfect.

Only one of my three smart TVs have the auto power off function, which I agree is very odd.

They are both Toshibas, so perhaps they are less bothered by that sort of thing.

Great - thank you for the pointer about the Zigbee mesh. Wifi sockets are slightly cheaper but the mesh improvement would definitely outweight that.
