Utility meter strange behaviour

Configuration
1

Hi All,

I have a solar system (Huawei 2000L) and thanks to huawei_solar integration (https://github.com/Emilv2/huawei_solar) i can get data from it.

The huawei_solar integration give me the real time solar power and power meter grid power (exchange with the grid +/-) and the daily_yield (total FV energy producted)

i’m using “utility meter” and “integration - Riemann sum integral” for calculate daily energy daily energy autoconsumend.

strange behaviour is that the utility meter my_home_daily_energy_autoconsumption every day start correctly when FV switch on but it doesn’t have a gradual course, it starts with a jump… so the auto-consumed energy is higher than the FV production…

any idea?

Thank You!!

Can you please post your configuration for your integral sensor?

Thank you for you response…
this is my config:

sensor.sun2000l_4_6ktl is the sensor created by huawei_solar integration

Thanks

Try setting the method to left. Read the paragraph under that link as to why.

I have followed your advice. I let you know how it works

Thanks a lot

the jump is smaller than yesterday but it’s there…:frowning:

I had a look at the sensors available from this custom integration. You have:

“grid_exporterd_energy” [sic] and “total_yield”

I’m not 100% sure what these are but would this not work (written in correct template format of course, not the pseudo code below)?

my_home_power_consumption = total_yield - grid_exporterd_energy

If this is the value you need you can feed it directly to the utility meter for a daily value, no integration required.
