SolaX cloud for Home assistant Based on version 2 of the API

SolaX Cloud Integration for Home Assistant (Based on API V2)

This Home Assistant integration fetches data from the SolaX Cloud using the official API V2, as described in the 1.2 API documentation. It was initially developed as an improvement over the API V1 integration from lowprice, from which it was forked. However, several significant changes have been made that a new repository was a logic choice.

Features:

  • The sensors are fully configured with measurement types, making them compatible with Home Assistant’s energy monitoring features.
  • Icons indicate the status of a device.
  • Difference witht the original version, is the use of a RESTful API.

Requirements:

  • Inverter Serial Number: Can be found on the Solax Cloud. The serial number of the communication dongle is needed.
  • Token ID: Generate here

Installation:

  1. Edit the secrets.yaml file (refer to secrets.yaml.sample for reference).
  2. Create a rest directory in the configuration directory (config/).
  3. Update the configuration file (refer to configuration.yaml.sample).

Additional Notes:

  • The SolaX Cloud site displays the total energy yield of the entire site, while the API fetches data directly from the inverter. This can lead to differences in the reported totals, especially if a new inverter was installed or there were issues during the initial setup.
  • For the most accurate and reliable energy data, it is recommended to pull information directly from the energy meter. The energy meter provides certified and precise readings, ensuring you get the correct data. Using the inverter's data might lead to discrepancies in total yield values.
