Homematic thermostat switches back to set value

Hi !
I have serveral homematic thermostats configured and they worked well… (ok during summer time you not really have attention to them , so date from which it started the weird behaviour is unkown)
e.g. the device is a HM-TC-IT-WM-W-EU.
the setup
thing:

Thing HM-TC-IT-WM-W-EU     MEQ0049842  "TH WZ_Komplett"

item

Number  TWZ_SOLL_TEMP   "Soll - Temperatur [%.1f °C]"    { channel="homematic:HM-TC-IT-WM-W-EU:ccu2:MEQ0049842:2#SET_TEMPERATURE" }

so its called in sitemap

Setpoint   item=TWZ_SOLL_TEMP   label="Soll-Temperatur"         icon="temperature"   step=0.5 minValue=4.5 maxValue=30.5

now to the log

2023-11-29 23:17:36.552 [INFO ] [openhab.event.ItemCommandEvent      ] - Item 'TWZ_SOLL_TEMP' received command 22.5
2023-11-29 23:17:36.552 [INFO ] [penhab.event.ItemStatePredictedEvent] - Item 'TWZ_SOLL_TEMP' predicted to become 22.5
2023-11-29 23:17:36.553 [INFO ] [openhab.event.ItemStateChangedEvent ] - Item 'TWZ_SOLL_TEMP' changed from 22 to 22.5
2023-11-29 23:17:52.635 [INFO ] [openhab.event.ItemStateChangedEvent ] - Item 'TWZ_SOLL_TEMP' changed from 22.5 to 22

As you can see i set temperature through the sitemap from 22 to 22.5 degrees… but 16 seconds later (this values differs …) the value is set back to 22 degrees which is set from the device (device isnt touched)

do you have any hint where it does come from ?

Ciao Gerd

I had some similar issue, where I didn’t know where the new Setpointtemperature came from.
I removed all the profiles in the CCU for that Thermostat, also for the Temperaturesensor and the Heatinggroup and since then it’s gone.

What you mean with remove profile ?
delete all items in CCU and reinstall them ?
