OpenZWave thermostat radiator issue

[renerene]

Since my last Domoticz update, I've been experiencing problems with updating and reading thermostat values on my Z-Wave radiators. This issue is particularly puzzling because I'm still using the OpenZWave USB method, which, despite being an older Z-Wave implementation, has been working fine until now. Because it is not supported anymore, you would not expect changes in old behaviour.

Temperature values coming in ok.
