Suunto and Assioma PRO RS-2

Thank you. Well, I just wanted to have some information about how good they work with the Suunto watches.

Are there any flaws one needs to know before “investing” that amount of money.

I remember back in the days, the Suunto watches could only receive power frome one pedal, even when you use a dual side power meter. Is this still the case after the recent updates?

Just things like this. Thank you.

@Stoke80 I have DUO version. No problem with pairing. You can only see total power, not separate L/R.
But I suspect that Suunto counts the time from automatic pauses into the average power even so it shouldn’t. I never got same values from Wahoo and Suunto if I have some auto pauses during ride. If I reduce the average power from Wahoo by a proportional amount taking into account the pauses, I get the same power, or a maximum difference of 1W. Normalized power is always same. So don’t be afraid, you can use it without problem!

@HonzaS said in Suunto and Assioma PRO RS-2:

ver got same values from Wah

Thank you vm for your answer. It’s exactly those things I was looking for.

@Stoke80 You’re welcome. Tomorrow, I’ll ride to cottage and back. 40+40km without pause. I’ll let you know, if I got same average power. I’m curious about that.

I have Assioma duo and Race 2. No issues, really. There are minor differences between what SA displays and what my Garmin bike computer does, but generally, nothing to worry about. Algorithms differ between companies and after a while you should be able to figure out what differences are there and this works.

@Stoke80 @honzas avg power on Suunto will be higher than bike computers, I use karoo third gen, the reason is Suunto computes avg power leaving out zeros ( e.g. While coasting), good thing is they also give power with zeros. If you’re interested in L/R balance from Assiomas, then you’d have to use a bike computer. But as far as Suunto watch, Assiomas send the real power avg taking into consideration both sides and giving that computed to the watch, watch will only pair to one pedal, usually left one but that’s enough as soon as pedals are in Duo mode in Assiomas app.

@herlas Yes, Suunto shows both average powers, with and without zeros and in Wahoo settings, you can set if you want average power with zeros or without. I have set this to without zeros and I got SMALLER average power without zeros from Suunto than on Wahoo. Never got higher values from Suunto. On last ride, the difference was 3,6%. It’s clear, that algorithm will differ Suunto vs. Wahoo, but I think, this difference is high and this is the reason, that I’m not sure, if Suunto really doesn’t count auto pauses to the average power…
With connecting to device which doesn’t support dual sided wattmeter, Assiomas should send the instantaneous power at a given time and it should be the sum of both pedals.

EDIT: On ride with “longer” snack pause, the difference was 5,1%.

EDIT2: So no, the difference is not because of auto pause🫤.

@herlas

Thank you for those insights. Does the watch really still only connect to one pedal? I hoped that has been solved with one of the updates, which made the watches able to connect to more than one sensor of the same type. Or is there a difference between the Suunto Run and the other watches due to the different software?

Many thanks as well to the others for their answers.

Now I just have to decide whether I want to afford the pedals or not.

Since I’m more of an ambitious recreational athlete, I don’t really need it. On the other hand, I am a friend of technical gadgets. That’s why it appeals to me.

@Stoke80 I have Assioma DUO paired with V1. The watch connect to one pedal, but the readings are from the both pedals.

@Stoke80 one pedal will be enough, when Assiomas are working as Duo, they’ll be presented as one power source only. So it’s not an issue. Zwift works the same way, it can only read one pedal but it’s enabled to leverage the data sent by Assiomas and show you L/R balance.
