Hi,
Looks like I have noticed an issue in the Velbus integration of HomeAssistant.
When the temperature is dropping below zero I assume we have somewhere a incorrect translation.
If you look into the logs from the homeassitant you see that the temperatures are around 0°C, where I believe some of them are going below that and so showing the 127°C (where I believe it’s the high bit that is not being used for the - +)
Below is the log file only showing the temperatures (raw is lower in the topic)
