I am currently trying to build multi-channel gateway using a Raspberry Pi 3. I know there is a couple solutions for single channel gateway, but i would like a multi-channel one.
I have seen the Rak831 et Rak2245 HAT for the Raspberry Pi and i find them really interesting.
But! I would like to keep the Raspbian OS because i have installed my MQTT broker on it plus a couple of other things and from what i’ve seen, if i want to use one of the Rak HAT, I will have to install the OS too and doing so, wiping everything on the Pi.
So! My question is : Is there another way to program the HAT using python or shell scripts and if yes, is it possible that someone provide me with examples? I have found nothing or almost nothing on the web and it would help me
Also, i am open to different ideas
