Thermia Online API

A Python API for Thermia heat pumps using https://online.thermia.se

Confirmed Thermia models that API supports:

It is hard for me to keep track of all models that I have added feature support for in the past, so, to understand if your model is supported, please try running the example file and see if it works. If it does not, please submit a bug report.

Regarding unsupported models

I am willing to do my best to support them, but as there turns out to be many different Thermia models and configurations, it is hard for me to implement all functionalities and test them thoroughly. Thus, I have created a debug() function that runs when example.py is executed and creates a debug.txt file which has data about your heat pump and all its supported features. If you want to submit a bug or feature request, please include the debug file as it will make my development much easier.

Note: I have done my best to remove the sensitive parts from debugging, but I do not guarantee that no sensitive data is printed to the debug file. I have no intention of using it maliciously, but if you post the file publicly on GitHub, please make sure you remove anything you feel might be suspicious of sharing.

How to use api:

See example.py file for examples.

To execute the example file, first run pip install -r requirements.txt to install the required dependencies, then run python3 example.py to execute the example file. You will be prompted to enter your username and password, and then the example file will run. If do not want to manually enter your credentials every time, you can edit the credentials.py file and add your credentials there.
