Is there way to have the broadlink rm3 on a Vizio tv send a power command that only turns the TV off? I want it to turn it off when I leave but I have no concrete way of determining if it’s on or off because it’s not a smart tv.
Put an ESP in the USB port.
If it’s available then the TV is on.
Or you power the EAP from elsewhere and just use the USB power to sense if the TV is on via an voltage divider.
Is there a command that only turns it off?
Also a what?
No but if you know the TV is on, then send the command, if the TV is off, don’t
Ok what are talking about to plug into the TV’s USB port?
ESP8266 or ESP32, my preference would be to use ESP-Home
Seems like a waste of power I assume theirs a way to use off biased ir commands but idk how to manually add a command without a controller.
A typical TV uses about 200-300 w of mains voltage.
An ESP uses about 0.4 w of 5 volt.
So… Turn off the TV if you want to save energy.
I’m fairly sure the ESP consumes less than the TV does in idle.
If the TV has separate on/off commands then it’s possible, but most does not.
Oh that sucks
