High energy consumption by the pump in the off state. #559

Open krzbor opened 5 hours ago

krzbor commented 5 hours ago

I have a "K" series heat pump. When reading the "_Power_Consumption" and "_Power_Production" parameters, I was getting incorrect values of -200. However, I found in the source code (unfortunately, this is not documented in the MQTT guide) the parameters "_Power_Consumption_Extra" and "_Power_Production_Extra," which return reasonable values.

I have a question, though—when the pump is turned off, it consumes about 40W according to this data, and when it’s on but not operating, it consumes about 70W. This higher value is probably due to the operation of the water circulation pump. However, I am surprised by such a high consumption in the off state. 40W amounts to 1kWh per day!

I compared the power consumption for October. In HA, it was significantly higher than on the heat pump. However, when I subtracted 1kWh for each day, the results matched.

Is the reported 40W consumption reasonable and realistic? Are the "*_Extra" parameters reported by the pump, or are they calculated in HeishaMon?

How you metered it? Is it just showed in pump?

I can confirm, my pump (H series) while idle consumes around same amount Screenshot_2024-10-19-21-42-25-87_c3a231c25ed346e59462e84656a70e50

And i was totally wrong, o forgot that i in 2 zone setup (which i have) zone pumps are always running and drived from pump.. here is updated graph after switch pump's off

My pump (K series) – off state: 41W. The value comes from "Aquarea Heat Power Consumed"; topic: "panasonic_heat_pump/extra/Heat_Power_Consumption_Extra". I find it hard to believe that the new series consumes 4 times more power than the old series.

Yes _extra topic is for new pumps K/L series, heishamon don't do any calculations, everything is fetched from pump. Also please pay attention that pump don't have any energy metering devices. All is done by calculating by pump itself.. so don't blindly trust. Second if consumption is real.. it could be from heating elements.. it could be compressor heater, it could be drain pipe heater.. and so on..

Maybe someone has measured the actual power consumption in the off state? If the pump doesn't have a power consumption meter, it must be calculating it somehow. It's interesting that the value shown on the pump's own graph is different from what is reported through MQTT.
