 # Overview of tested Bluetooth LE sensors
 
 ## HRS: Heartrate Service
+
 * Decathlon|Geonaute|Kalenji Dual HRM Belt
 * moofit heart rate monitor
 * Polar H7
+* Polar H10
 * Polar OH1
   Has updatable firmware that requires a user account at polar.com
 * Wahoo Tickr (Model: WFBTHR02)
+* Mi Band 3, Amazfit Band 5, Amazfit Bip. These devices are manufactured by Huami, and other Huami devices will very likely work. Theoretically, this sensor must be enabled, but testing reveals that it works even without enabling. For details on how to enable see [Gadgetbridge wiki](https://codeberg.org/Freeyourgadget/Gadgetbridge/wiki/Huami-Heartrate-measurement#bluetooth-heart-rate-sensor)
+* Amazfit Neo. But first you have to enable "Discoverable" and "Activity heart rate sharing" in the official Zepp app. (after pairing with OpenTracks you can disable them again)
 
 ## CSCP: Cycling Cadence and Speed Service
+
 Please note that the according to the specification these sensors _may_ provide speed as well as cadence.
 However, often only one value is provided.
 
 ### Speed
+
+* Garmin Speed Sensor 2
+  * Has updatable firmware that requires an account for garmin.com
+  * This sensor reports speed data as cadence.
+    A workaround is in place.
+  * This sensor sometimes counts backwards (unknown software version).
+    A workaround is in place.

+## Cycling Power Measurement
+
+We only support _Instantaneous Power_.
+
+_WARNING_: we only support physically movements with valid GPS coordinates.
+Using a device indoors (no GPS available) will only show the current power values, but won't store anything.
+Also the distance is not computed.

-2. and also segment markers.
-   These are marked by PAUSE / RESUME TrackPoints.

-While exporting PAUSE/RESUME are not used to create these segments and these are partly recreated when imported.
-However, the timestamp of PAUSE/RESUME is not exported and can therefore not be restored.

+note right of Track
+A track is an ordered collection of one or more segments (i.e., continuous parts of distance covered).
+Segments may be started by a user (i.e., start a track recording, continue a paused track, or resume a track) as well as stopped by the user (i.e., pausing or stopping a recording).
+Also segments may started automatically while recording (i.e., distance to previous location was to large).
+Note that this finishes the previous segment.
+
+Segment data is stored as TrackPoints (Type.SEGMENT_START_MANUAL, Type.SEGMENT_START_AUTOMATIC, or Type.SEGMENT_END_MANUAL).
+Trackpoints with Type.SEGMENT_START_AUTOMATIC also mark the end of the previous segment.
+All TrackPoints of Type.TRACKPOINT belong to the segment started by the prior TrackPoint with Type.SEGMENT_START_(MANUAL|AUTOMATIC).
+Trackpoints of Type.SEGMENT_START_MANUAL or Type.SEGMENT_END_MANUAL do not contain location data or sensor data.
+
+Tracks recorded prior to OpenTracks version 3.15.0, do neither begin with a Type.SEGMENT_START_MANUAL nor end with a Type.SEGMENT_END_MANUAL.
