FoxESS and Home Assistant integration 🏡 ☀

⚙️ Installation & ♻️ Update

Use hacs.io to manage the installation and update process. Right now this integration is part of HACS by default - no more neeed to add it by custom repositories 🥳

⌨️ Manual installation

Copy content of custom_components folder into your HA /config/custom_components folder

💾 Configuration

Edit your home-assistan /configuration.yaml and add:

sensor:
  - platform: foxess
    username: foxesscloud_username
    password: foxesscloud_password
    deviceID: foxesscloud_inverter_id

Auxiliary notes:

• foxesscloud_inverter_id in UUID that can be found on the foxesscloud in the url path on the Inverter Details page. ⚠️ Please make sure that this is exact value from inverter details page address between = and & character:
• Multi-inverter support - if you have more than one FoxESS device in your installation, you can leverage the optional name field in you config, if you want see an example check out here
