Huawei Solar Sensors

This integration splits out the various values that are fetched from your Huawei Solar inverter into separate HomeAssistant sensors. These are properly configured to allow immediate integration into the HA Energy view.

Installation

1. Install this integration with HACS, or copy the contents of this repository into the custom_components/huawei_solar directory
2. Restart HA
3. Go to Configuration -> Integrations and click the + Add Integration button
4. Select Huawei Solar from the list
5. Enter the IP address of your inverter (192.168.200.1 if you are connected to its WiFi AP). Select if you have a battery and/or optimizers. The slave id is typically 0.

Inverter polling frequency

The integration will poll the inverter for new values every 30 seconds. If you wish to receive fresh inverter data less (or more) frequently, you can disable the automatic refresh in the integration's system options (Enable polling for updates) and create your own automation with your desired polling frequency.

FAQ - Troubleshooting

Q: Why do I get the error "Connection succeeded, but failed to read from inverter." while setting up this integration?

A: While the integration was able to setup the initial connection to the Huawei Inverter, it did not respond to any queries in time. This is either caused by using an invalid slave ID (typically 0 or 1, try both or ask your installer if unsure), or because an other device established a connection with the inverter, causing the integration to lose it's connection

Q: Will the FusionSolar App still work when using this integration?

A: The inverter will still send it's data to the Huawei cloud, and you will still be able to see live statistics from your installation in the FusionSolar App. However, if you (or your installer) need to use the 'Device commissioning' feature of the app, you will need to disable this integration. Only one of them can be connected to the inverter at any one time.

Q: I can't get this integration to work. What am I doing wrong?

A: First make sure that 'Modbus TCP' access is enabled in the settings of your inverter. Next, check if the port is correct. Some inverters use port 6607 instead of 502 (this can change for you after a firmware update!). If that doesn't work for you, and you intend to write an issue, make sure you have the relevant logs included. For this integration, you can enable all relevant logs by including the following lines in your configuration.yaml:

logger:
  logs:
    pymodbus: debug # only include this if you're having connectivity issues
    huawei_solar: debug
    homeassistant.components.huawei_solar: debug

By providing logs directly when creating the issue, you will likely get help much faster.
