Which is the most accurate treadmill sensor & how to connect it to Home Assistant?

Last Updated on November 10, 2023 by pg@petergamma.org

We do not know that for sure. But the North Pole Engineering Runn Treadmill Sensor is one of the most accurate treadmill sensors. Also fellnr tested the NPE Runn:

his conclusion:

«So, is it worth it? Well, the sensor is fairly cheap, listing at $99 at the time of writing, and it’s almost certainly vastly more accurate than your treadmill display, and more accurate than the accelerometer in your running watch. It’s more accurate than a standard Footpod, and while Stryd is remarkably accurate outdoors, Stryd tends to struggle on a Treadmill due to the speed variations.

Runn is also a convenient approach, and if you took the time to calibrate your treadmill, you could add the calibration factor into most running watches.

The Runn also measures incline, though I’m not sure what software would support that measurement. I’d love to have incline data from my treadmill runs, but it may require a custom Connect IQ data field.»

NPE Runn and Home Assistant

If you want to have your NPE Runn data in Home Assistant we can use Balena Health. Treadmill speed sensors use the foot pod protocol. We can modify Balena Health for foot pods. Then we can connect Balena Health to Balena Home Assitant over the Balena Cloud. But to test if this works is something for people with advanced coding skills.
