Communication between Pis on different networks (self.raspberrypi)

submitted 8 months ago by illectrility to c/[email protected]

I'm sorry if this isn't the place to ask this, I also asked over at [email protected].

So what I want to do is this: Two RasPis are at different locations. They're on different networks but have internet access. Pressing a button on one of the Pis turns on an LED over at the other Pi via GPIO. How can I make the communication work? My first thought was Telegram bots as I'm familiar with those for notifications but you can't have Telegram bots communicate with each other, sadly. Is there a good (and secure) solution to this? Preferably using Python code and without continuous costs like server hosting, etc?

Thanks!

After you have set up the VPN (tailscale etc.), you could use pigpio.
