Aeotec multisensor 6 temperature bonkers

All my Aeotec multisensor 6 have decided that if it’s cold outside(around below 0C) it’s 6555 - actually temperature..

If it was one I’d replace it but it’s all making me think it’s a driver issue.. But I have the factory z wave sensor driver..

Any suggestions?

No problem with my two sensors, using the Aeotec driver, available on Aeotec Group Channel,
