Control 433 MHz RF module on remote PI


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!

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.
