I had originally installed a SmartSunt 500a in my campervan and added the auxiliary starter battery voltage cable to the sunt. I recently added a Raspberry Pi 3 with the Venus OS v2.73 and love using the VRM portal.
My question is id like to add 2 temperature sensors to the system. One for my 12v refrigerator and one for inside the van to see the ambient temperature.
If anyone has done this in the past id love to hear which sensor you used and how you plug it into the raspberry pi.
Thanks
