        Hi, I’ve the same issue. I’ve a Suunto Race. Everything is perfect except the heart rate measurement.
        Not reliable at all.
        I’ve already resetted the factory setings without any improvement.
        For instance, last training : 1st hour was perfect around 130 bpm, then the last 3 hours were at 180 bpm which is not possible! same pace rate.
        I need help
        Thanks
        Yann

          @YannH Suunto OHR does not work well for me either running or SkiMo. I use a belt. OHR varies for individuals. Even my Apple Watch does not work well for running intervals.

          For sleeping 24/7 day use the OHR is great for me.

            @YannH If you notice your BPM reading getting funky, what you can do is stop running for 1 minute, usually your HR goes much lower and “external noises” (like the bumps from running) are non existent, which allows the HR sensor to lock again on the correct beat.

            Also, pay attention to the watch placement for optimal HR :

            • Place the watch on the “meatier” parts of your wrist (ideally at least one cm before your wirst bone)
            • wear it tight enough so that there is no movement
            • Make sure you are warm on your wrist, with gloves and stuff, because the cold weather makes your blood vessels constrict on the limb extremities where its not needed, thus make it much harder to read

              The HR recording on my RaceS stopped yesterday. I didn’t get any sleep score this morning but kind of thought it was just an oddity and didn’t notice the lack of green light but I noticed after my yoga session that there was no HR data and then noticed I was also missing HR data all day.

              Checking back in the app, it looks like HR stopped being recorded after I partially charged the watch from 14% to 74% yesterday about 10am. My run yesterday was was fine because I use a belt but the rest of the data is missing.

              I rebooted the watch and HR is back but I noticed the watch face, while the correct style, had reset its complications and highlight colour. I just thought it worth mentioning that in case it was an indication of a corrupt config file or something.

              I am on the latest firmware and I’ve not had this issue before.

                I have to reboot from time to time. first the HR starts getting more and more inaccurately. Then it hangs on a fixed value for a time or jumps between to values - 129 an 68 for example in a yoga session last week. after rebooting the watch, it works fine again for a time (3 days to 3 weeks)

                    @watwatch I think it is usable for everyday tracking…

                    If you wanna have a review for this, watch dc rainmaker… He was very positive about this.

                      @watwatch This is my exact use case. I only rely on the OHR for everyday life/sleep/activity. For any sort of timed activity I always use a HR strap. Used this way the Race S works pretty well for me.

                          I’m having issues with the heart rate sensor. It drops out randomly for no obvious reason.

                          The first picture is on a gravelbike, but on flat asphalt road. Second picture is real gravel road and actually in the flat part, i was doing concrete roads.

                            @brechtvb I’d really recommend an external HR device for any sport such as running or cycling, especially gravel bike or mountain bike. The well respected Reviewer DC Rainmaker basically finds watch OHR never performs well when there’s a lot of movement/vibration. Coospo do some pretty cheap but decent belts and armband OHR sensors (although with optical you won’t be able to use ZoneSense) or there’s the well known manufacturers such as Suunto’s own belt, Wahoo, Polar and Garmin.

                            Wrist based OHR is fine for everyday and good enough for aerobics, spin classes or rowing machine but for anything more it’s worth the external sensor 🙂

                              @far-blue Below the picture of a bike ride (asphalt, nearly no gravel) with a garmin forerunner 55 (the el-cheapo).

                              The drops in heart rate are perfectly explainable to the speed drops. All dots together: a today 150 euro garmin outclasses a 350 euro Suunto in measuring heart rate.

                              i have plenty more with (nearly) zero heart rate error.

                                @brechtvb I’m glad you feel you can rely on it for your activities 🙂

                                However, the internet is littered with posts, comments and reviews from thousands of people who can’t, regardless of whether it’s a $100 amazfit or a $1000 Fenix. The wrist is pretty much the worst possible place to try and take an optical HR reading.

                                  @far-blued I’m really unhappy with the optical heart race on My Suunto Race S, the data is inconsistency even though I follow all the wearing tip from the manufacturer. I have not get the similar issue with other optical watch brand.
                                  It is very annoying when going out for a run then suddenly there is no heart rate signal on watch or it jump extremely high.

                                    @far-blue I sold the forerunner because I sint want to deal with so many devices, obviously.

                                      There is a new update: 2.40.38
                                      who knows this solves a thing.

                                        @brechtvb For me the update solved nothing, perhaps made the OHR situation worse, i.e. fewer reasonable readings (not exercising).

                                            @erik_ibk I have the same problem and these are vital things to work so I’m really disappointed this issue has been constant for weeks and nothing is being done, even if MANY people are having the same issues. I think I might return the watch since these issues have been here the whole time I have had this. So disappointing.

                                            I can’t just be restarting this all the time and I can’t know when it is not going to measure the sleep. So it’s not helping to restart to get that sleep data back. How is it possible that there has been promised update but it’s been WEEKS? this would have never happened with Garmin. So I guess I have to return this then?
