Suunto Smart Heart Rate Belt keeps losing connection to the watch
-
This evening it happened with my race s and polar oh1+
Heartrate band disconnected, didn’t reconnect and the buildin heartrate sensor didn’t take over.
My stryd stayed connected though.
I will report to suunto support.

It isn’t supposed to be taking over.

@2b2bff but it seems it does. At least on the Suunto Run. I saved today’s run to report tomorrow.
2 issues happened. Max heart rate much higher than registered on the HR chart and in the end I did a pause and the connection to the Suunto Chest Straps was lost when I restarted a few seconds later.
The maximum HR registered by the chest strap was 154bpm but somehow on the Max HR in the intervals summary many values of 170bpm (these are wrong) appears. Also it can be seen that the HR chart doesn’t end. It was the pause. Unfortunately Suunto seems unable to solve this issue that affects all watches and makes all data contaminated by wrong measures or lack of them.

Sorry to hear about all the problems people have. Have Suunto acknowledged there is a problem and working on a fix or has they already “posted” the fix but it still remains?
-
@Henrik-Nilsson they gave me a predefined answer with the usual stuff… It’s strange how a bug of this magnitude does makes them more proactive to solve it.
-
@Nelson-Diogo I agree. Hopefully they are aware and working on it. It seems wierd selling products that are supposed to be used together and they arent =).

@JaakkoK
I have recently experinced tha same issue with a smart belt bought in february. Lately short disconnections occurred, which had never happened before. Lastly, on Sunday after a couple of short dicinnections, the belt and the watch never reconnected for the rest of the workout. After the end of the session, i restarted another one and the watch saw the sensor without issues. Nevertheless, Given that in 10 years i have replaced several sensors because faulty or dead, i attribute this to the sensor, not the watch. Fiven that i bought it on amazon, i returned it and bought a new one, so let’s see.
The suunto smart sensor is not exactly a piece of reliable engineering, actually is quite crap, as i said i replaced several of them, i guess some 5 or 6 since 2015 -
@sindavide I’m also almost sure the the issue I have it’s a faulty Suunto Chest Strap. The Suunto Run is behaving awesomely for me in any other respect.

I don’t have a Suunto chest strap.
I think the problem with mine is a combination of my stryd and a polar oh1+ (although I think the heart rate sensor is irrelevant)
The stryd causes some odd behavior when I do warmup exercises at my athletics club. While doing planks, my watch buzzes due to some signal from my stryd (is my assumption, the buzz is real, the cause is assuming) and after that my watch loses connection to my heart rate sensor.
Last couple of weeks we didn’t do that kind of exercises and I had no problem with disconnecting heart rate sensor.
I suspect the problem is in the watch firmware. It either cannot handle certain signals from my stryd or it cannot deal with disconnecting sensors.

Same problem here, Suunto Smart Sensor connected to a Race 2. Worked flawlessly for seven months until last Sunday when suddenly the sensor connection dropped after starting the run. First idea was of course the battery, inserted a new one, problem remained. Chest strap is always washed after training, bought a new one anyway, problem remained.
I measured the resistance of the brand new strap and the older one; new one has approx. 1.38 kOhms (2x700 ohms), older one has 2.85 kOhms (2x1.43 kOhms), but up to now I heard that the straps should be good if they are below 8-10 kOhms.
Warm reset of the watch did not help, re-pairing the sensor did not help as well. I have no idea why that happens; the last firmware update of the Race 2 was beginning of April, and the watch performed without any hiccup afterwards.
I did a factory reset last night, will try again this evening whether that helped. Also bought a Polar H10 as backup solution… so that sensor problem cost me more than 100 EUR up to now (btw, 39 EUR for a replacement strap is much more expensive than Polar, they sell replacement straps for 25 EUR).
Suunto wants to sell the Race 2 as a training device for runners - training without a reliable HR detection is no option, though. I do not want to use OHR as well, it’s usually quite a few beats off if I am not just sitting at a desk.
Any other ideas except for “the suunto smart sensor is not exactly a piece of reliable engineering, actually is quite crap”?
