Good morning Dacian,
Yes, this is a bit puzzling. I will go ahead and connect ADC2 or 3 to the +battery and further investigate to determine the root cause. The temperature should be close to ambient (~15C) and I have not connected the temp wire yet. So, I am not sure why there is a 31C temp indication.
My unit is installed on the boat and we are currently cruising Pacific North West with the hope that Canadian border opens up to the cruisers soon. So, I am not able to remove and return the unit at this time. However, I had planned to order another SBMS0 as spare to keep on the boat. I will go ahead and do that. As soon as I receive the spare, I will install and see if the problem is resolved. If so, then I will return the first unit at that time. Regarding spare unit, I have couple of questions:
- Do I need to have a Wifi module to have EXTIO5 and EXTIO6 available?
- How soon will a new SBMS0 be available? When the unit is available, will determine which address it needs to be sent to
