openzwave fails to update domoticz setpoint

[Nomader]

i have installed the srt323 thermostat a few weeks ago. everything is ok except:
i have noticed that sometimes when the value is changed using the thermostat on the wall and specially when the value is changed rapidly (e.g: change to 20C leave for 1 second and change to 25C) the value although is changed correctly in the openzwave, domoticz fails to show the correct value. The only way to get domoticz to show the correct value is either:
1. shut down the server and start it again
2. change the value on the thermostat on the wall once again

i repeat, openzwave works and updates fine, even the log shows the update. it is just that domoticz fails to be updated

any suggestions?
