POPP 010101 Radiator Thermostat Temperature Spikes

Configuration Z-Wave
1

Hi,

I’ve installed a POPP 010101 (danfoss) z-wave radiator thermostat (I also use danfoss Ally).

I’m getting a strange issue on the air temperature reading. Occasionally it will report an extreme temperature. It’s not a major issue but it’s really messing with the feng shui of my temperature graphs.

To me it looks like some weird issue parsing the number which I assume should be 18.44 C? Has anyone else seen it or something similar?

Do you know if the issue is recent?
I came to the forum for trying to find out why my energy meter went bananas the past two days, it has been working very well until the last upgrades of HA and Zwave JS - average consumption has been 45 kWh per day, yesterday HA logged a whopping 60,5 gWh - but if I check the sensor in zwave JS it looks absolutely normal with a total (some years of consumption) of around 22 mWh

I only installed this thermostat on the 13th January.

16th and 18th January I had the issue so far.

I don’t know if it can be of any help - resolved my spike issue which occured daily - the power meter was set to report every 2 minutes, after setting it to every 4 minutes I have not seen any spikes for the past week
