Issue with mysensors DHT sensor

Hi, a while ago I had a couple of mysensors DHT sensors working correctly with Home-Assistant, reporting both temperature and humidity just as they should have. However battery life was an issue so I put the project on hold.
I have now resurrected the project, I have a new install of HA version 0.105.4 and have reconnected the sensors, which are exactly the same. However the temperature is not being reported correctly. The humidity is working fine. Has anyone else come across this issue?
The humidity sensor looks like this
