Growatt API client

This Python script logs in to server.growatt.com and retrieves data on solar panels.

Usage

Create a new GrowattApi instance, log in, retrieve a list of plants and request details of these plants. An example can be found in growatt/__main__.py, and can be run using python -m growatt.

API

Currently this package uses an API that I reverse engineered the API from the Growatt mobile app. This is more of an internal API that can be changed by Growatt if they want.

There is also an API specification for a more standard API, but that is currently not used by this package.

Getting started

Run the following commands to set up a new virtualenv and run the growatt API example:

git clone https://github.com/Sjord/growatt_api_client
cd growatt_api_client
python3 -m venv venv                    # create a new virtual environment in the directory 'venv'
. venv/bin/activate                     # activate this environment
./setup.py install                      # install all dependencies
python -m growatt 'username' 'password' # retrieve data for today

After setting up like this, you can just run the python from the virtualenv each time you want to run it:

venv/bin/python -m growatt 'username' 'password'

If you want to create your own client, start from growatt/__main__.py. Copy it and change it to your liking, and then run it like this:

venv/bin/python myscript.py 'username' 'password'
