Huawei Solar sensor

This code is a custom component to read the data from Huawei inverters

Install

Available with HACS (Home Assistant Community Store)

This is a custom component. Custom components are not installed by default in your Home Assistant installation. HACS is an Home Assistant store integration from which this integration can be easily installed and updated. By using HACS you will also make sure that any new versions are installed by default and as simple as the installation itself. Currently this custom component is not in the HACS repositories, in the HACS documentation you can find how to add a custom repository.

Manual

Copy the custom_components folder into your HA configuration folder (if you already have the custom_components folder, copy the huawei_solar folder into it).

Then configure the sensors by setting up the huawei_solar platform in configuration.yaml.

Options

Name	Type	Requirement	Description
host	string	Required	hostname or ip address
optimizers	boolean	Optional	Set to true if you have optimizers and want to see information about them.
battery	boolean	Optional	Set to true if you have a battery and want to see information about it.
slave	int	Optional	Set the slave unit, set slave = 1 when using the dongle.
port	int	Optional	Set the inverter ModBus TCP port

Example:

sensor:
  - platform: huawei_solar   
    host: '192.168.0.123'
    optimizers: true
    battery: true
    slave: 1
    port: 6607

Troubleshooting

If you are using the SDongle to communicate with your inverter, make sure the following conditions are met

• Dongle Firmware must be at least at version SPC123 (You can ask the support to update yours remotely, provide your dongle SN. Alternatively obtain the firmware file from support and install it through the App by connecting to the Dongle management Wi-Fi (available for 3 minutes after startup).)
• In the Dongle settings (Settings/Communication settings/Dongle Configuration, log in as installer to the inverter), make sure to set Modbus-TCP to Enable(unrestricted) or set an allowed IP if using restricted mode
• According to the Modbus TCP Guide, the inverter needs at least version SPC139
• set slave: 1 as described above
• Make sure no other client is accessing the Modbus TCP interface

If it is still not working after that, restart the inverter and try again.

Breaking Changes

1.0.0

• Sensors names now include the serial number. If you have existing templates/lovelace/automations you should update those to the new name or use the UI to change the name back to the old name.
• the daily_yield, total_yield, storage_charge_discharge_power, storage_total_charge and storage_total_discharge are now separate sensors instead of attributes.
