Integration Solar inverter huawei 2000L

[jorgejs]

Goodnight

First of all, thanks to @Emilv2 for the great script he has made and to everyone who has contributed to this forum thread. It works perfectly for me and everything is great in home assistant.

The only problem I have is that some attributes are not clear to me and I would like to know which attributes correspond to those shown in the following image (from the Huawei solar fusion application).

On the other hand, I would like to know if it is possible to configure home assisant to perform it as a service and have several entities (instead of a service with attributes). In other words, to be able to have the values ​​that are in the attributes independently.

Thank you very much again. THANK YOU, THANK YOU and THANK YOU.

• 1 is input power
• 2 is the state of the device
  - 3 and 4 are unfortunately not accessible as far as I know. I don’t have this meter but others have tried and could not get it. Same thing for 5, 6, 8 and 9.
• 7 is daily yield

Separate sensors is a good idea and should be done to make it officially into HA.

EDIT: Seems like I remembered wrong about the power meter values.

[ligeza (Rafał)]

1. input_power
2. value of sensor.sun2000…
3. power_meter_active_power
4. it’s counted (value of sensor.sun2000 - power_meter_active_power)
5. it’s counted (7 - 6)
6. grid_exporterd_energy
7. daily_yield
8. grid_accumulated_energy
9. it’s counted

Integration Solar inverter huawei 2000L

Hello first thank you very much for the contribution, it is fantastic. I need to know if this information can be extracted (in the image numbers 1, 2, 3). If possible, how should I do it or what are the parameters that I have to read [IMG_20210117_191319] Thanks a lot

[jorgejs]

Thank you very much for the answer.

Would it be possible to put these values ​​as independent sensors?

[ligeza (Rafał)]

You can use template sensor. I think it is better option then independent sensors because I can chose which sensors I want, instead of having over 50 sensors.

- platform: template
  sensors:
    m_grid_exporterd_energy:
      friendly_name: "Prąd oddany do sieci"
      unit_of_measurement: 'kWh'
      icon_template: mdi:transmission-tower
      value_template: "{{ state_attr('sensor.sun2000_8ktl_m0', 'grid_exporterd_energy') }}"

[Thull3]

Cant you post your hole list of configuration.yaml of the huawei settings ??

Please that have been much appriciated

Hello,

I want to integrate a Huawei SUN2000 inverter - 5KTL-M1, using HA on an Rpy3.
Rpi is connected to the router via LAN. Router and Rpy IP is 192.168.16.xxx
The inverter is connected to the router via wifi dongle. (without battery and optimizer)

I read the previous posts, and I can’t make this integration. That’s what I’ve done so far:

I found out the address of the inverter, I checked it:

>>> import huawei_solar
>>> inverter = huawei_solar.HuaweiSolar ('192.168.200.1')
>>> inverter.get ("model_name")
Result (value = 'SUN2000-5KTL-M1', unit = None)

I created the folder and put the necessary files in it, and wrote in configuration.yaml:

sensor:
   - platform: huawei_solar
     host: '192.168.200.1'

ping seems to be a problem …
74 packets transmitted, 0 packets received, 100% packet loss

Then with nmcli wifi device, SUN2000-HVxxxxxx appeared but with a weak signal (15) - is that the problem ???

I do not know what to do anymore…

Thanks in advance for your help!

[ligeza (Rafał)]

Do you see any errors in HA logs? I see that connection from python works, so is rpi connected to inverter internal wifi (you can’t connect this integration to smart dongle)? Did you try move rpi closer to inverter to test it with better wifi signal?

@ligeza

so is rpi connected to inverter internal wifi (you can’t connect this integration to smart dongle)

Rpy is not connected via dongle, I think it is connected via wifi (nmcli shows Sun2000 …). Maybe I don’t know how to connect Rpy to the inverter’s internal wifi …

I will try to bring Rpy closer to the inverter.

It is problem with connecting to inverter, can you ping 192.168.200.1 from rpi?

[MirceaD (Familia Domsa)]

No, can not ping, as I said:

I don’t know why.

Is it still working? Was it from rpi? Can you show network configuration from rpi? On rpi you shoul have 2 IP, one from home network (LAN) and one from Inverter (wifi)

[MirceaD (Familia Domsa)]

It shows me a single eternet connection.

I think I have to do like here: (post LGHD)

Integration Solar inverter huawei 2000L

I didn’t setup WiFi upon installation of the Pi so use the method in which I connect a USB stick named “CONFIG” with directory network and a file named “my-network” with below code. (I’m on the road now so not able to give you the exact code, but below my best recollection) [connection] id=my-network uuid=72111c67-4a5d-4d5c-925e-f8ee26efb3c3 type=802-11-wireless [802-11-wireless] mode=infrastructure ssid= SUN2000-HV1990005631 # Uncomment below if your SSID is not broadcasted #hidden=true [80…

if I do this, Rpy stays connected to the router on the LAN and connected to the inverter on Wifi ???

… I’m sorry for my stupid question, but I’m newbie… and thank’s for your answer…

[MirceaD (Familia Domsa)]

@ligeza

It is from my laptop, near the inverter

[MirceaD (Familia Domsa)]

@ligeza

[ligeza (Rafał)]

No connection to inverter, I don’t have rpi, so I can’t help you configure wifi.

[Emilv2]

Yes, as I understand it if you do this you will stay connected to the router via LAN and connected to the inverter via Wifi. If it works you should see an ip address behind IPv4 addresses from wlan0 in the System information.
