I’ve got a Multiplus 45/5000 and Cerbo GX at the moment all temp sensors have been used, now I’m making a heated box for the batteries and would like to see the temp of those as well when I go on the VRM, I know the ruvvi Bluetooth temps work but one they are expensive and two I would prefer a hard connection so one is there a cheap alternative or could I wire the Multiplus T-Sense in the box only issue is that I won’t be able to connect it on to the neg terminal of the pylontech is there an issue with that not being connected?
