Hi!
I would love to be able to control my TVs with Home Assistant.
Today i can turn off/ set volume on 1 of the TVs. The other one do not work.
However, i did read some on HDMI CeC, and both my TVs support this. Can i use HA to turn on/off etc. the TVs with HDMI Cec? Do I need too connect my HA Raspberry PI to a device useing HDMI? Or can i send this over the network?
CEC communicates via the HDMI cable so you would need something connected to the TV you want to control. If the TV is connected to the network there may be ways to turn the TV on and off across the network outside of CEC. If you have some streaming device connected to TV you may be able to send a command to the streaming device to issue a CEC command to the TV.
I have a Raspberry PI connected to a TV in the kitchen. The TV occasionally turns itself on and I do issue a remote ssh command to turn it off. I don’t use that within HA but I certainly could. So, there could be several ways to remotely control your TV.
