Z-Wave Thermostats stopped reporting air temperature

Hi I’m using Hass.io installed in a VM with the new OpenZwave Beta. The stick is on a rapsberry pi in the optimal position in the house.

Since a reboot of the OpenZwave Beta, the sensor entity of my thermostat is not updating anymore:
ie: the climate.xxx-thermostat entity has the right current air temp in the json data but the sensor.xxx-thermostat-airtemp sensor has been stuck for multiple days.

Does anyone have an idea?
