Integration Solar inverter huawei 2000L

yousaf465 · August 27, 2021, 4:14pm

Finally got it to work. Connected to Huawei 10KTL-M1 using Raspberry pi’s builtin wifi.

Supervisor
System
click change next to IP address
select Wlan0
Select wifi and scan for access points.
Connect to SUN2000-xxxxx (xxxxx being your Inverters’ serial number) password is “Changeme” if it wasn’t changed
add the following code to configuration.yaml file.
restart HA.
It will add a new sensor name " sensor.sun2000_10ktl_m1" or whichever the model of your inverter is.
follow @Emilv2 and @ligeza 's advice for further queries. because I don’t know next steps at this stage. @iz3man thanks for rpi4 advice. temporary solution but a solution non the less.

This is the code I used in configration.yaml file

sensor solar:
  - platform: huawei_solar
    host: '192.168.200.1'
    optimizers: false
    battery: false

can someone please help me to explain how to setup with LAN cable beacuse my RPi4 cant find the inverter wifi anymore.

But i can find it by my phone so it works .

But i got the dongle uppgraded to version 122 but cant get it to work .

Everyone seems to type different things in there config file ??

Can anybody typer their setting for LAN cable

tremebundo · August 28, 2021, 2:42pm

I have made it work.
My scenario is not the common one. I have not my HA instance running in a RPI. It is on a Intel miniPC away from the inverter.
So, I have used an old TPLink router with wifi to route and masquerade the traffic between the internal inverter AP to my local network.
I have followed this tutorial that I got from this thread:
https://skyboo.net/2021/07/how-to-connect-to-sun2000-from-dd-wrt/
I had some trouble adapting it to my settings, but I finally got it.

Thull3 · August 28, 2021, 3:51pm

My RPi4 cant see the Wi-Fi anymoore i have had it working before so now i want to have it working with LAN cable.

Now I get that there is already someone connected ??

Do I use Emil’s or modbus in config ??

tremebundo · August 28, 2021, 6:10pm

I have just started with Emil’s custom component. But I still have not made anything with the sensor values.
My plan is to make some automations based on the consumption and generation.
Also, I would like to use the new “Energy” feature in HA, but on my first attempt, I could not see the sensor in the config wizard. The HA docs state that Modbus should be valid, but I would like to support Emil’s work.

yousaf465 · August 29, 2021, 6:52am

did you try Guide: Connecting Pi with Home Assistant OS to wifi (or other networking changes)?
check with the following commands

curl -v 192.168.200.1

and check ping

ping 192.168.200.1

to kill the ping Ctrl + C

Thull3 · August 29, 2021, 7:07am

The wifi don’t show up in the rpi4 anymore … it’s located 2 meters from the inverter .

It don’t connect to it by WiFi …

I have now it connected by Lan and now get someone already connected

could not read register value, is an other device already connected?

I can ping the LAN ip with good reslut but still get the error message

**I Now managed to get into the inverter and changed the inverter wifi password and then it poped up in RPI4 again … so i am now connected **

yousaf465 · August 29, 2021, 9:11am

Your Ping and Curl -v response should be like this.

yousaf465 · August 29, 2021, 9:28am

Now I am trying to set up separate sensors.
I used the following code

template:
  - sensor:
    total_yield:
      friendly_name: "total yield"
      unit_of_measurement: 'kWh'
      icon_template: mdi:transmission-tower
      value_template: "{{ state_attr('sensor.sun2000_10ktl_m1', 'total_yield') }}"

but in log I got this error

Logger: homeassistant.config
Source: config.py:445
First occurred: 2:12:44 PM (1 occurrences)
Last logged: 2:12:44 PM

Invalid config for [template]: [total_yield] is an invalid option for [template]. Check: template->total_yield. (See /config/configuration.yaml, line 30).

what I am doing wrong here?

yousaf465 · August 29, 2021, 2:19pm

@ligeza How did you removed W.distinct legend. it is showing up in my graphs

Thull3 · August 29, 2021, 2:52pm

What attributes do you use at the new Energy tab

My Exported Energy shows unknown …

Can someone provide with a copy of your configuration file please ??

yousaf465 · August 29, 2021, 4:07pm

Here is my configuration.yaml there is some mistake with sensor template which I can’t understand, but rest is working fine. I am connected via RPi4

sensor solar:
  - platform: huawei_solar
    host: '192.168.200.1'
    optimizers: false
    battery: false
template:

      value_template: "{{ state_attr('sensor.sun2000_10ktl_m1', 'total_yield') }}"

Do anyone have this working ???
I only get unknown

ligeza · August 29, 2021, 6:22pm

       value_template: "{{ state_attr('sensor.sun2000_15ktl_m0', 'grid_exporterd_energy') }}"

change to

       value_template: "{{ state_attr('sensor.sun2000_15ktl_m0', 'grid_exported_energy') }}"

Thull3 · August 29, 2021, 6:38pm

Took me many times to read what the different was but super thanks

tremebundo · August 30, 2021, 6:03pm

Hi all,
I have configured and have access to the sensor created by Emil’s custom component and I created sensor templates for many attributes as @yousaf465 do.
But I could not use any of them for the new Energy feature in HA.
Anyone has been able to use that way?

yousaf465 · August 30, 2021, 6:26pm

for that, you will need to you need to check @ligeza’s video or this link Integration Solar inverter huawei 2000L - #589 by yousaf465

Evka2k · September 2, 2021, 7:53am

I added template sensor like this:

sensor:
  - platform: template
    sensors:
      pv_total_yield:
        friendly_name: "Total Yield"
        unit_of_measurement: "kWh"
        icon_template: mdi:solar-power
        value_template: "{{ state_attr('sensor.sun2000_8ktl_m0', 'total_yield') }}"

And this:

homeassistant:
  customize_glob:
    sensor.pv_total_yield:
      last_reset: '1970-01-01T00:00:00+00:00'
      device_class: energy
      state_class: measurement

energy_sun2000

yousaf465 · September 2, 2021, 9:51am

what I am doing wrong?

 pv_total_yield:
        friendly_name: "Total Yield"
        #entity_id: sensor.sun2000_10ktl_m1
        unit_of_measurement: 'kWh'
        icon_template: mdi:solar-power
        value_template: "{{ state_attr('sensor.sun2000_10ktl_m1', 'total_yield') }}"

and

      energy_used:
       friendly_name: "total energy used"
       unit_of_measurement: 'kWh'
       value_template: >
         {{ '%0.2f' | format(states('sensor.total_yield') | float - 
                            states('sensor.grid_exporterd_energy') | float +
