Grott Home Assistant Custom Component (grott)

Custom component (installable via HACS) for registering sensors associated with Growatt inverters that are being published via Grott. See prerequisites for more information.

NOTE - While it is probably possible to run both this Integration and the growatt_server_api integration at the same time, it is not advised. I recommend disabling the previous integration to avoid clashes.

Installation

Before installing the Integration, please ensure you have followed all steps in the prerequisites section i.e. you have a working Grott -> MQTT setup.

This integration can be installed via HACS for Home Assistant

1. Install HACS (Follow all the way through to the 'Configuration' page)
2. In HACS install this integration:
   1. Click 'HACS' on the left menu
   2. Click 'Integrations'
   3. Click the three dots in the top-right corner
   4. Click 'Custom repositories'
   5. In the 'Repository' field enter: https://github.com/muppet3000/homeassistant-grott
   6. In the 'Category' field select 'Integration'
   7. Click 'Add'
   8. Once the repository is added click on Grott
   9. On the next page select 'Download' in the bottom-right corner
   10. Choose the latest released version and click 'DOWNLOAD'
   11. Click the 'HACS' button in the menu and restart Home Assistant when prompted
3. Once the plugin is installed via HACS configure it just like a normal Home Assistant Integration i.e. from Settings -> Devices & Settings -> Add Integration -> Search for Grott

or (if you don't want to use HACS)

1. Download the latest release to your custom_components folder inside the Home Assistant configuration directory and unpack it

Implementation

On initial release this plugin works in read-only mode and pulls data from an MQTT server that has been pushed to by Grott (more information/how to configure this here)

The future plan will be to grow this project so that it allows configuration of inverters via Grott also.
