Does anyone use EMHASS and have a working control for huawei and luna2000 that they can share?
Hi,
the Modbus specs report the availability to read the Insulation Resistance, but I did not have this value in the HA integration. Is it not available or itâs a problem of mine?
Hello, this is my card yaml file but canât figure out how to have the actual house consumption and the correct value for the actual energy imported from the grid.
Any help?

Thanks for sharing, I added the lines into the configuration.yaml file but Iâm missing the sensor.house_power_consumption entity.
Using Huawei Solar integration Iâm having just 67 entities vs. 117 via Fusion Solar integration.
Iâm just having the followings:
its this one to build:
Note: change the âstatesâ's sensors according your built
{% set meter_power = states(âsensor.power_meter_active_powerâ) | float %}
{% set inverter_power = states(âsensor.inverter_active_powerâ) | float %}
{{ (inverter_power - meter_power ) | float(0) }}
it will show up a new one called âhouse_power_consumptionâ
- sensor:
- name: âHouse power Consumptionâ
unique_id: âhouse_power_consumptionâ
unit_of_measurement: âWâ
device_class: power
state_class: measurement
state: >
{% set meter_power = states(âsensor.power_meter_active_powerâ) | float %}
{% set inverter_power = states(âsensor.inverter_active_powerâ) | float %}
{{ (inverter_power - meter_power ) | float(0) }}
Thanks Pedro I think I did it correctly and restarted HA but still canât find that sensor.
EDIT: I see the entity now but it returns no figures:
Hereâs my config.yaml file:

unique_id: "house_power_consumption"

do you have this?

its wrong, switch
{% set meter_power = states('sensor.power_meter_active_power') | float %}
{% set inverter_power = states('sensor.inverter_active_power') | float %}
{{ (inverter_power - meter_power ) | float(0) }}
soo yours

{% set inverter_ptenza = states('sensor.inverter_potenza_attiva') | float %}
{{ (inverter_ptenza - meter_potenza ) | float(0) }}
Hey Pedro many many thanks.
Yes I got the sensor.house_power_consumption entity now and switched the config.yaml code as suggested but on the power flow plus card Iâm still getting this wrong value: grid is likely my home consumption
type: custom:power-flow-card
entities:
battery:
consumption: sensor.battery_day_discharge
production: sensor.battery_day_charge
battery_charge: sensor.battery_state_of_capacity
grid:
consumption: sensor.inverter_active_power
production: sensor.power_meter_active_power
solar: sensor.inverter_input_power
inverted_entities: battery, grid
EDIT: figured out it was a typo, many thanks @Pedro_Trancoso for supporting!
Much better but Iâm getting strange values now. House consumption is higher than energy taken from grid (battery is below the minimum SOC so not giving any energy and PV are not producing as itâs 10 pm)
I connect to my SUN2000-33KTL-A via ELFIN-EW11. The connection is successful, through the browser I made the settings according to the instructions. But when I set up Huawei solar integration, I get a message âFailed to connectâ almost immediately.
Is my inverter not compatible with this integration? Software version V200R002
MBUS Software Ver. V100R001C72SPC102.
Here is the log message:

Hey, I have passed the whole day on this. Getting crazy. Looking to grab live data from my 3 8ktl-m1 with 2 batteries to manage mypv elwa2.
I have done my possible to connect to modbus with ew11 It is currenty connected to main inverter on port rs485A1(2), and rs485B1(4). But canât seem to get this through. Any help would be greatly appreciated.

Standardisation of WLCRS (Huawei / iStore) Custom Sensors?
Apologies this was the only forum I could think of that would allow tagging both of you in (vs your own seperate GitHub Repos). Iâve been working on a number of derived / custom sensors (for use with SunSynk card for Huawei / iStore) from WLCRS ârawâ sensors and looking around you also have done the same.
Wondering if instead of there being multiple different developments of derived sensors, each with different names and/or unique_idâs for the same sensors, if it would make sense to pool efforts and have one standard set of custom sensors for WLCRS users?
In this way, it would allow all WLCRS end users to have a single and consistent set of sensors they can easily add to their HA, and in doing this be able to easily then leverage them for different visualisations/cards that people have developed.
Thoughts⌠?
Here my âprojectâ in Home Assistant
If you are interested i can send you the code
Iâm configuring several actions when my inverter Huawei M1 10 KTL is Off Grid (i have a Backup Box), and i need to identify the EXACT value for DEVICE STATUS when the inverter is OFF GRID
When itâs ON GRID, the value is âOn-gridâ, i suppose that for OFF GRID the value should be âOff-gridâ
Do you have a list of these kind of values ? Could you help me ?
Thanks a lot

The outputs of WLCRS for Huawei are all based upon the âModbus Register Definitionsâ as published by Huawei.
The âDevice Stateâ you mentioned is register # 32089, also 32000 - 32003
Look in at lines 10 - 41 of the Library that WLCRS uses to query this state, for the possible replies he caters for:
Interested if you can send me your card, as Iâm trying to work out what the dial is for on the bottom left ?

Struggling to get this Template Sensor right. Itâs reporting always the wrong value for my House consumption and i think it must have something to do with positive and negative values of battery_charge_discharge_power and power_meter_active_power because they both can have negative and positive values. So iâm not a math genie and iâm struggling to think clear about this maybe because i tried so much. I think it has something to do with substract or addition of the values and the order in which this should be calculated. So maybe somebody has a hint for me?
template:
- sensor:
- name: "House power Consumption"
unique_id: "house_power_consumption"
unit_of_measurement: "W"
device_class: power
state_class: measurement
state: >
{% set meter_power = states('sensor.power_meter_active_power') | float %}
{% set inverter_power = states('sensor.inverter_active_power_group') | float %}
{% set battery_power = states('sensor.battery_charge_discharge_power') | float %}
{{ (inverter_power - meter_power - battery_power) | float(0) }}
Edit:
Just thought about it and i think i have to take out the charging power of the Battery if it charges. Same is for the power from grid. I should only use the imported power from grid to calculate house consumtion. So there should only the positive values used for calculation and i can not figure out how to only use positive values of those two entities.
Iâve replied above
you are inserting the batery, and canât
- sensor:
- name: âHouse power Consumptionâ
unique_id: âhouse_power_consumptionâ
unit_of_measurement: âWâ
device_class: power
state_class: measurement
state: >
{% set meter_power = states(âsensor.power_meter_active_powerâ) | float %}
{% set inverter_power = states(âsensor.inverter_active_powerâ) | float %}
{{ (inverter_power - meter_power ) | float(0) }}
Hm, but shouldnt i?
I think if i only use Power of the battery and not from grid. Letâs say 400W, my home is consuming 400W. Not from grid and not from one of my inverters. So i thought i have to take the battery in this calculation alsoâŚ
I just want an entitiy for the power consumption of my house, not what im consuming from grid or solar etc. I want a total of all consumed energy and that includes power i take from the batterys or am i wrong?
