SAJ eSolar Sensor Component

This is a Custom Component for Home-Assistant (https://home-assistant.io) reads and displays sensor values from the SAJ eSolar Portal private API.

NOTE: This component is built upon a none public API and can change/break at any time. The component is built with 2 device to test with used in the Netherlands and Malaysia. Please go to the Supported devides part to see if your device is supported

Installation

HACS - Recommended

• Have HACS installed, this will allow you to easily manage and track updates.
• Search for 'SAJ eSolar'.
• Click Install below the found integration.
• Configure using the configuration instructions below.
• Restart Home-Assistant.

Manual

• Copy directory custom_components/saj_esolar to your <config dir>/custom_components directory.
• Configure with config below.
• Restart Home-Assistant.

Note when updating from v1.0.0.4

- resources are renamed in de configuration, replace old ones. applies when updating v1.0.0.4 -> 1.0.0.5
