I was wondering if there is any chance that I could make my Samsung Smartthings Hub v3 turn on and off my TV which is not a smart tv of any kind, but just a HDMI-CEC capable tv with a Chromecast plugged into it.
I can use my google speaker and assistant to turn it on and off - but would like to be able to do it in automations.
So like when everyone has left the house - it will turn the TV off.
When someone comes home - turn it on again.
If you can connect the TVs to the Alexa app you could use a simulated Alexa switch to connect it to Smartthings. I don’t think you need a physical Alexa device, but I could be wrong.
I have a Vizio TV set up that way and it works. It only gives you on/off control. But I do have physical Alexa devices.
