ZWave CT101 thermostat not showing Operating State

[alfredosc8]

I'm running Domoticz V4.9701 on Linux and zwave is controlled by aeotec zstick.
The thermostat looks like working fine,I can control it as well as showing temperature and humidity but there are no devices showing the operating state, aka when it is on on heating or cooling or idle.
Looking the status I saw:
OpenZWave: Value_Added: Node: 21 (0x15), CommandClass: THERMOSTAT OPERATING STATE, Label: Operating State
and on logs
OpenZWave: Unhandled class: 0x42 (THERMOSTAT OPERATING STATE), NodeID: 21 (0x15), Index: 0, Instance: 1

How can I fix it.
I want to record when the heater is on or off.

Thanks
