@teddycricket said in sleep tracking not working after most recent update: A soft restart returned the heart rate. As you did, I’ve always soft reset the watch to restore the functionality of the OHR sensor; however, yesterday I’ve tried to restore the sensor by switching on and than off the “Power Saving” mode: it worked! In this way you do not have to synchronise the watch before the reset to keep the latest data, obviously in case of you do not keep your watch constantly connected to the phone via Bluetooth.

@thanasis Yes, Suunto Smart for all the activities. I was afraid to ‘activate’ the battery drain using it, but no problems with current firmware

@OutdoorMan i’m to lazy to keep pressing snooze each 10 minutes Anyway, there are other uses. I use it to remember me to take my medication, sometimes I know I will only be home in an hour. When that happens I dismiss the alarm. I don’t want to snooze each 10 minutes for one hour…

@Audaxjoe correct; you can “force stop” the app (SA) and it helps. Btw. I had this problem for a while, but it disappeared around two weeks ago. Maybe, the new version of SA solved it

@Jan-Krejčí it should not be a problem. I use Race 2 on the outside of my jacket when biking and XC skiing. I guess biking is not cold enough (around O C), but I XC skied in -20 C without any problems. Previously, I used S9B and skied at close to -30 C on a few occasions with no issues. I think the specs talk about -20 C or even -25 C. When it is colder we should stay at home .

@Valentin-Schulz You could wait for an update that should be soon but this should not be happening. I would try a hard reset but that seems to be what has happened. Try a hard reset and if still an issue it might be faulty hardware and will be replaced.

@vinc14 no, only in suunto app.

@vinc14 you can lock the watch during the activity - go to Control panel (or hold the bottom button) - Button lock. Do the same to unlock.

Last night my watch also stopped measuring heart rate in the middle of the night. I bought the watch only 6 days ago. A soft restart returned the heart rate. I have software 2.48.16

@mikajahkola Perhaps you could record this as treadmill running which allows calibration once you’ve stopped recording on the watch. After you’ve calibrated it, it should become more accurate.

They’ve just given me the problem and the solution: apparently, the watch has to be in contact with the skin. If you wear it over clothing, the wrist-raise gesture doesn’t work.

I use the Race 2 with Wahoo HR strap and it works with no issues. The strap connects to my bike computer and the watch when I ride, or just to the watch when I XC ski.

After a few weeks of testing, the issue started to occur again. The OHR sensor turns off without warning and does not turn back on until the watch is removed from the wrist or a forced restart is performed. [image: 1766748113856-img_5821.jpeg]

I’m still not sure it makes total sense, but anyway both Shimano Di2 and Shimano E-Bike systems (STEPS) were updated to support all bike/e-bike activities

I had a problem with repeatedly connecting and disconnecting my Garmin chest strap, but all I had to do was turn off encryption on it.

@sky-runner Thank you for your response. I couldn’t react since I can’t log in on my phone. I was away a few days. I didn’t use snap to route. I was just following my route and decided to go different. I just ignored my watch and didn’t change a thing. Battery mode was performance mode. Hopefully I’ll do another run the next days. But these are busy days
