Hoping someone can help me figure out why temp sensor is showing open circuit.
I switched to a Cerbo unit 3 months ago as I wanted the extra temp sensor inputs, the Venus was working perfectly when I packed it away in it's box.
This week I have made up an 8s LFP 24V battery config with a 2.2 KVA Studer Inverter just for my 900W water pump as the house lights often dim when the pump starts up and it bugs the wife :-)
I thought I would make use of the Venus GX again so bought a SmartShunt and hooked everything up it's all working fine but... I have tried 3 different Victron temp sensors (the blue tag ones) and they all show 'open circuit' on both Temp 1 & 2 of the Venus? Thinking there might be a problem from the data already on the Venus from previous install I did a factory reset using the procedure in the manual with the latest swu firmware v3.41, that went okay but the temp sensor still shows as 'open circuit'. I have the red wire connected to Temp 1 (or Temp 2) and the black wire to GND, not sure what else to try it worked perfectly before with two sensors connected.
The temp sensor shows up in the remote console and VRM device list but no widget
Any help to diagnose much appreciated.
