I am stumped on this. I’d like to have a tile to turn my vizio and lg tv on and off on my dashboard. Well smartthings does not support any other tvs. I tried making a routine in alexa and adding the alexa virtual switch handler. Still the smart things won’t find load my tv. Ether I am doing something completely wrong or is there another way around this?
SmartThings may not officially support other TVs directly, but I would suggest searching through the SmartThings Community to see if there are any community developed integrations. For example, it looks like there are a number of community developed integrations for LG TVs (though I haven’t personally tried them).
This sounds like a neat workaround. SmartThings won’t be able to find the TV directly in this case (or know the status if you control it from a different device), but if there’s an Alexa integration for the TV then this sounds like a reasonable workaround.
Another approach would be to use something like a Harmony Hub or Broadlink IR device.
