Start Raspberry Pi with TV
I have an old TV without HDMI CEC so it won’t startup when I’m starting the Pi. I’m going to connect a Sonoff as a remote switch to turn everything off when I’m not home, but when I turn the power back on the TV is in standby and to start it I’ll have to use a remote.
Is there a way to make the Raspberry Pi send a signal to the TV and wake it up?
You sort of need to do this in reverse.
But yeah I would do some googling on the pi being a ir reciever / sender
There’s no way to make the Raspberry Pi send a button prompt or some kind of electric signal via the GPIO?
@hallonpaj sure, can do… but someone will probably has to write code (module) to make that happen…
@hallonpaj Yeah of course it could you can get a 3.3v relay and its a 2 wire job to GPIO
But what are you going to wire it to?
What you do is put an IR Led on a wire and your Pi is now a universal remote for any device in range via LIRC.
Its a LED + resistor and two wires.
Yeah a pi could with the right interface also do powerline comms but your TV can not so that would be a bit pointless
Took your advice and now it’s working perfectly. Big thanks for the help!
I should of mentioned these things, doh!
But basically a Pi with an IR LED
