I have a cerbo gx with two temp sensors with one selected for battery temp charging and the other for room temp. I then installed a smartshunt and discovered the SOC was not using the temps for accurate SOC. So i installed the correct temp sensor on the smartshunt. With this temp sensor installed…

The shunt i would expect would normally show the temperature in the battery widget if it is set as the system battery monitor, since it is related to battery data. It won’t affect SOC for lihtium but does affect temperature compensation charging and soc for lead based systems And setting alarms re…

Yesterday I went to the site and shut off the inverter for some ac wiring work, turned it back on and left. I didn’t spend and time on the smartshunt as I’m not sure what to check next. I wiggled a few connections on it only. This morning in the VRM portal I looked at the Device list and it showed t…
