Temperatures from Techem FHKV data II/III (fhkvdataiii) very off - normal?

[muhkuhgh]

Hello everyone,

I just bought a suitable USB Stick and after some complications I've got this set up and running tonight and my current HCAs are already being stored in mySQL database.

I find some readings very disturbing.. most of my rooms are like 20 °C and the water temperature for heating is below 70 °C in our house afaik.

Are your temperature values as worse and unusable as mine?

7 different devices.
118 °C .. seriously? :D I mean that would explain the already 1600 hca for this radiator this year..

Also: I guess it is not possible to get decimals for HCA as they are probably just using internal but not send out - right?
