sensor.comfoairq_ventilation_total_energy_usage not working

[m67hoff]

I have noticed that the total energy consumption sensor is not really working. It always shows the same value. In my case 279 kWh (it jumps irregularly to completely 0).
I assume that this is a bug in the Comfoconnect LanC. But this is the only community where I can ask whether this is just me, if you also have this error and know a possible solution. (I know I could calculate the total energy in HA by integrating the actual power usage)

Thanks and greetings from Germany - Michael

I understand that the sensor is only full kWh. My ComfoAir use about 30W -> what would sum to 1kWh every 1.5 Days. But my "total consumption" stays at 279kWh now for Month. (See for graph whole Dec above) I noticed that this is the value also the ComfoConnect App shows. So does anyone has this working? Can we open a ticket at Zehnder?

BTW: Does your integration support the "Total consumption per year" (as in this screen shot - since this seems to increase)

This seems to be a Zhender issue as I have noticed the same behaviour in my ComfoAirQ. The "Power Consumption" "Total from start" is only increasing for 2 kWh/month since August 2024 onwards. Looking at "Total year-to-date" currently shows 3 kWh which seems correct for these three days of 2025 (incl come preheater consumption).

Yes seems so - I checked with a - he has the same bug (not using HA at all). So we can close this. And I try to find out if I can open a ticket a Zehnder.
