English translation of our conversation with Apple Watch & Stryd Foot Pod expert DailyNerdAlert (see YouTube comments):
Peter Gamma:
I need as accurate data as possible on distance, speed, steps per minute and stride length to practice walking meditation indoors on a treadmill. When I attach a foot pod to a Garmin watch, I have all this data calculated by the foot pod in Garmin Connect. Can I access this data with an Apple Watch with Stryd? And can I manually calibrate a Stryd paired to an Apple Watch? What I like about the Apple watch is that I can sync measurement data from Apple Health to Home Assistant via the Health Auto Export iPhone app. Is the mentioned Stryd data exported to the Apple Health app? That would be great, because Garmin watches make it difficult to get this data.
DNA – DailyNerdAlert:
Hello Peter – you can also calibrate the Foodpod manually on the Apple Watch. Stryd only transmits the values: weight, activity energy, heart rate, distance, training and training distance. Regardless of the device, you can find all the data in the Stryd power center… are you already using a Garmin watch?
Peter Gamma:
Yes, I have several Garmin watches. At the moment I mainly use a Fenix 6 because it provides the breathing rate. But that is inaccurate. So I’m looking for a way to get the sensor data into a database. It is possible to sync data via Strava in Home Assistant. The breathing values, for example, would first have to be read out of the .fit file, and that is complicated. The Stryd data doesn’t seem to look much better than the breath values either. Of the parameters I mentioned – distance, speed, steps per minute and stride length is available as just the distance or training distance as you say. Do you know how to synchronize the other parameters like speed, steps per minute and stride length in InfluxDB or Home Assistant for example?
DNA – DailyNerdAlert:
You have the option of downloading the FIT files directly from the Stryd Power Center – there you have all the data.
Peter Gamma:
Yes, the .fit file option is already available for Garmin watches. But to put them in a readable format we need a Python tool by computer scientist Max Candocia. And then we have a new .csv file again. For me personally, InfluxDB is interesting. You can stream in different sensors and the timestamps are in sync. So far, only the Apple Watch can do this with the Health Auto Export iPhone app. But that only seems to work to a very limited extent with Stryd data.
