A Python library to interact with the API behind the myVAILLANT app ((and branded versions of it, such as the MiGo app from Saunier Duval). Needs at least Python 3.10.
Warning
If you're using sensoAPP or the multiMATIC app, this library won't work for you. Try the pymultiMATIC library instead and check Vaillant's website for more information.
This integration is not affiliated with Vaillant, the developers take no responsibility for anything that happens to your devices because of this library.

pip install myPyllant..or use Docker, if you just want to use it as a CLI tool:
docker run -ti ghcr.io/signalkraft/mypyllant:latest python3 -m myPyllant.export user password brand --country countrypython3 -m myPyllant.export user password brand --country country
# See python3 -m myPyllant.export -h for more options and a list of countriesThe --data argument exports historical data of the devices in your system.
Without this keyword, information about your system will be exported as JSON.
python3 -m myPyllant.report user password brand --country country
# Wrote 2023 report to energy_data_2023_ArothermPlus_XYZ.csv
# Wrote 2023 report to energy_data_2023_HydraulicStation_XYZ.csvWrites a report for each heat generator, by default for the current year. You can provide --year to select
a different year.

I'm happy to accept PRs, if you run the pre-commit checks and test your changes:
git clone https://github.com/signalkraft/myPyllant.git
cd myPyllant
python3 -m venv .venv
source .venv/bin/activate
pip install -r dev-requirements.txt
pip install -e .
pre-commit install
pytestThe myVAILLANT app uses Keycloak and OIDC for authentication, with a realm for each country and brand. There is a script to check which countries are supported:
python3 -m myPyllant.tests.find_countriesCopy the resulting dictionary into src/myPyllant/const.py
Because the myVAILLANT API isn't documented, you can help the development of this library by contributing test data:
python3 -m myPyllant.tests.generate_test_data -h
python3 -m myPyllant.tests.generate_test_data username password brand --country country..or use Docker:
docker run -v $(pwd)/test_data:/build/src/myPyllant/tests/json -ti ghcr.io/signalkraft/mypyllant:latest python3 -m myPyllant.tests.generate_test_data username password brand --country countryWith docker, the results will be put into test_data/.
You can then either create a PR with the created folder, or zip it and attach it to an issue.
- Auth is loosely based on ioBroker.vaillant
- Most API endpoints are reverse-engineered from the myVaillant app, using mitmproxy
