Heatpump board - Random temperature errors, reading -0.1

Started recently it appears. Just the temperature inputs.

@TrystanLea any ideas?

Hello @jbetech, Have you checked the connections? any chance water may have got into the sensor?

Click on this checkbox show missing data and then zoom right in on the graph.


Might be missing data.

Hello @TrystanLea

I will double check connections today.

One of the sensors is measuring outdoor air and will get wet.,… Need protecting?


Thanks for the suggestion. I checked and it is not missing data, actual data point at -0.1.

It should not need protecting if its the encapsulated waterproof type… I’ve got mine attached to the grill at the back of the heat pump which gets all the weather thrown at it.

I will do some fault finding. Thanks
