I’ve spent a couple of hours trying to find a simple RF TV remote receiver that can integrate with HA, and so far not turned up much apart from IR Blasters.
I have two LG TV’s which both use LG Magic Remotes, and both are powered from Zigbee Smart Sockets. Using the built-in power monitoring on the smart sockets, an Automation will turn them (and any associated kit) off when the TV is put into standby mode for longer than 10 minutes. Works like a charm.
To turn them back on though, I have to end up shouting at Alexa, so I thought I’d get a higher WAF by having a small RF sensor to monitor when the TV Remote ‘On’ button is pressed, and then, using HA to trigger the socket to turn on.
I do have a few ESP32’s knocking about, so could go down that route if it’s the only option.
Are you doing this to save money on electric? If so you may want to work out how much you are saving by using a smart plug over just leaving the TV in standby. I have never worked this out but a smart plug can use up to 1/2 a watt and some TV’s on standby only use a tiny bit more. This info was just from a quick google, I have no solid figures to prove either one. Sure someone here will know.
Maybe saving less than £1 a year. WAF is worth far more than that
No, it’s not to save on the electricity at all - the total used by the stuff on standby is negligible really in the whole scheme of things (although I have a couple of HDD’s docked to the lounge TV which draw more power than I thought they would ).
It’s more of an OCD thing really. I just hate seeing stuff on standby - brought up by tight-arse parents I suppose.
If it can’t be done, fine. I’ll not be losing sleep over it, but I just find the process of sorting it out interesting and challenging too.
