But if Home Assistant expects data in real-time, how can data from Garmin Connect, Polar Flow, and Fitbit Dashboard be streamed into Home Assistant? These platforms are not real-time devices, and there are integrations for these platforms availabe in Home assistant???.
I can’t speak for the other integrations but I used the Fitbit integration for a while. The data was timestamped by home assistant as the sensors updated. e.g home assistant would poll the step count from the Fitbit cloud periodically and when the data was retuned the value would be assigned the current time.

Thanks for the answer, this is great .
It would be interesting to have data from Fitbit, Garmin and Polar all synced into Home Assistant, and to start some data analysis there. Which is the most accurate activity tracker?
According to this paper, the Polar OH1 sensor:
with an accuracy which is near to an ECG device. It should be possible to stream in the Polar OH1 sensor in in real-time over the Polar Sensor Logger app, with has MQTT support, and use it as a reference device.
Enric Sala, Software Engineer and PhD in applied Data Science, according ot his GITHUB a diligent Software Engineer:
developed the InfuxDB client for Matlab to stream house sensors into Matlab. I guess he started his work before Home Assistant was there.
My personally, I would be happy to have the sensor data from Fitbit, Garmin and Polar streamed into Home Assitant to start with a data analysis. Unfortunately, Polar import does currently not work:
Polar was specially interesting, since it allowed to import all activity data from a Polar watch into Home Assistant. With the Garmin watches, we can only have the wellness parameters.
It would be highly desirable, when someone managed to make the Pola Home Assistant integration run again.

The “Activity Data from Strava directly into Home Assistant” project seems to be running :
