Hardware recommendations for RV setup

Hi all,

thinking about equipping our RV with an OpenHab system to automate and monitor some stuff. For our stationary home, I’ve been using a lot of AVM hardware + Shelly for switches, temp & humidity sensor connectivity, etc. This may not be an ideal option since on board electricity is 12 V and 24 V DC, with 230 V AC only available via converter and not preferred for extensions.

Any hardware suggestions? I’d need to hook up a bunch of temp sensors and switch a few 12 V consumers, e.g., for tank heating, and would ideally like to integrate the various level sensors etc.

With regard to the central “control unit”, I’d stick with a Raspi 4, which works well in our stationary setup, as well.

Any suggestions/experience reports would be much appreciated.

Thanks a lot in advance!

Best,

Sven

There’s Shellies you can operate on 24VDC, too.
Should wiring be an issue, consider ZigBee or ZWave, sensors operate on battery.

Tx. for the suggestions! Just checked - you are correct, it seems like the entire Shelly plus series support 12 and 24 V DC supply. Had just checked the Gen 3, which don’t, apparently. Shelly “Uni” also looks interesting. Does anyone have experience with such setups in RV, camper vans, mobile homes, exmos etc.?
