Room temperature is doubled from 15 sept

[Rodio]

Hi All,

Finally found some time to check a weird issue.
From 15 september my room temperature is doubled, so if the room is 20degrees the value give 40.
Funny part is if I set the room setpoint to 21, the room temperature will be 42.
As far as i know I don't have any blocky and/or LUA script connected to the OTGW.
I'm running the latest (stable) firmware of the OTGW (USB version) and always the latest version of Domoticz (currently 2.3702)
The OTGW is connected to a Remeha terra with an iSense.

Thanks
