Control 433 MHz RF module on remote PI

[qrioniclabs]

Hi!

I have a PI with an Arduino attached, which has a 433 MHz RF module connected. How can I send the commands via that PI to the Arduino? The rpi_rf switch looks like it only works ony the local system, but I need to control the RF module on that (remote) PI.

Any help appreciated. Thanks!

Hi, All I’m new to home assistant. I have a generic RF 433 MHZ PIR motion sensor, I want to configure when it detect motion it will trigger light switch to turn on. I’ve gone through the forum and cookbook and couldn’t able get it work. Do anyone have experience with the same configuration? Thanks.

You would have to subscribe to a topic to receive commands, but that would be possible. The fact that your board is on a different Pi is not relevant for MQTT to work.
