error in the load energy

[nebbiadigiorno]

hi, i noticed an error in the total power use by the house (se the screenshot).

this is the code for the card that i am using:

if you see the power use by the house it lacks 300 watt, that difference is displayed correctly in the other card. Both cards is using the same sensor.
Any ideas?

ps. i don't have a goodwe inverter but a zcs by zucchetti.

Hello. Since you don't have a sensor defined for essential_power the card is trying to calculate it for you based on the formula below

essential = load_power_L1 + load_power_L2 + load_power_L3

Which in your case is sensor.phase_a_power + sensor.phase_b_power + sensor.phase_c_power

What value do you get when you add these manually?

[nebbiadigiorno]

i get the value display in the card, that is the same from the grid and the load. In the ha forum you tell me not to use the essential sensor but to use the 3 phase sensors. The card should consider the solar production, what goes to the battery and what goes to the house.
This sensor is the same i am using in the other card, that display the value correctly

[slipx06]

Can you show us your sensor values for the Grid and Load from HA developer tools?

[nebbiadigiorno]

the grid and the load has the same sensor, and in the screenshots are the "fase a,b,c" in the central card. What you want to see from the developer tools?

[nebbiadigiorno]

[nebbiadigiorno]

this are the sensors provided by my inverter integration:

[slipx06]

Can you provide a link to the integration you are using in HA

[nebbiadigiorno]

yes, https://github.com/StephanJoubert/home_assistant_solarman

[slipx06]

What inverter definition are you using? This one does not have many sensors https://github.com/StephanJoubert/home_assistant_solarman/blob/main/custom_components/solarman/inverter_definitions/zcs_azzurro-ktl-v3.yaml

[nebbiadigiorno]

i am using the sofar_g3hyd.yaml

OK change your sensors (check the name) for the load to these and test:

load_power_L1: sensor.solarman_ActivePower_Load_R_EPS
load_power_L2: sensor.solarman_ActivePower_Load_S_EPS
load_power_L3: sensor.solarman_ActivePower_Load_T_EPS

and similarly change your grid sensors to these:

```
grid_ct_power_172: sensor.solarman_ActivePower_PCC_R
grid_ct_power_L2: sensor.solarman_ActivePower_PCC_S
grid_ct_power_L3: sensor.solarman_ActivePower_PCC_T

```
actually grid sensors should be

grid_ct_power_172: sensor.solarman_ActivePower_Output_R
grid_ct_power_L2: sensor.solarman_ActivePower_Output_S
grid_ct_power_L3: sensor.solarman_ActivePower_Output_T

[nebbiadigiorno]

nope the eps is not used in my system (the eps is the "ups" emergency system).
i used the active_power_load_sys in the essential power sensor and that does the trick

Ok. remember to set three_phase: false
