Fellnr has described a method for treadmill calibration:

- But it uses a high speed camera and the Kinovea software.
- It works but both hardware and software are a bit difficult to handle.
We have already another treadmill speed sensor based on Raspberry Pi:
- It should not be too difficult to update the instruction for Home Assistant.
- A speed sensor is quiet a basic sensor. We only need to measure the distance the treadmill belt moves in a certain time period and calculate the speed.
- If we replace the Fellnr calibration with the Raspberry Pi instruction we have more contemporary solution. The Pi instruction uses a hunt sensor with a infrared light and an infrared receiver:
- Is this not a better approach than a high speed video camera & Kinovea to create a DIY treadmill speed sensor?
This is a lot to digest for physiologists like we are. But if a fellnr among the Home Assistant developers is looking for a YouTube video demo, this one is available, and it is a great new challenging project for Home Assistant developers to develop a treadmill calibration method. But until a passionate Fellnr among the Home Assistant developers realizes this project we suppose that we stay with the original instruction by fellnr. It is an instruction also medical doctors can use to receive ther MD. and write a paper about it. The Home Assistant instruction is more suitable for final year engineering students of the Swiss Federal Institute of Technology in Zurich to do it fun an in their spare time.
