Suunto and Concept 2 indoor rowing

Oh yea, and another thing, when switching between PM5 workouts, the distance always reflects the last distance from the PM5,
Example, warm up row in “just row” shows distance for that, then switching to intervals, there is a new distance, then cool down row in “Just row” will be the last logged distance that then gets sent to the mobile app.
A solution could be to have a dedicated distance variable on the watch app that continuously adds the distances during the whole workout for later sending.

@peringmar I assume you’re not active during the rest portion of intervals? When I do interval workouts, during rest periods I continue to take light strokes at low power. Screenshot from intervals.icu
I consider a session as having continuous movement without stopping so if I were to do several 100m sprints and racking the handle in between, I’d record them as distinct sessions.
I’m similar with cycling and running. If I do intervals in cycling, I keep spinning during recoveries at low power, etc.

Think you miss interpreted what I wrote, so I hope this clarifies it.-
I too keep rowing at a slower pace in the rest sessions of intervals, but the issue that I posted was that when the rest session is activated when doing intervals on the PM5 (the interval mode) the last measured power and stroke rate keeps getting logged on the watch until the next interval starts. So no rest session power/stroke rate gets logged until the next interval starts.

A proposed solution for the distance was the following. Example:
10 minute warmup in “Just row” (2500m) gets written to variable “distance” on the watch.
Switch to intervals on PM5, the intervals (4000m), variable “distance” gets updated to 6500m
Exit intervals, cooldown in “Just row” (1000m)
final variable “distance” 75000m gets sent to mobile app, instead of just 1000m like its currently.

From my screenshot, where the continues lines lie at like 440 Watts during the rest mode instead of the actual power

Good work, guy. But really, there’s no need for a connection like this. The PM5 needs to be connected to a smartphone to plan and upload races. What we need is a connection from C2 to Suunto to actually use the load values in CTL/ATL, etc.

Ah, thanks for clarifying. I’m rowing on a WaterRower/SmartRow combination, and while I’ve done quite a bit of Concept2 rowing, I never used their interval mode. On the PM5, can you program to go from one work intensity to a second work differing intensity without a “rest” interval?

A connection from the C2 logbook to import into Suunto seems not within the scope of what is possible with a SuuntoPlus app, but rather, that ability would need to come from a collaboration of Concept2/Suunto themselves. If Suunto wishes to do that, then perhaps they can also talk to SmartRow so sessions from the SR logbook could also auto-upload to Suunto? http://www.smartrow.fit/
This setup would be for people not currently using the PM5 bluetooth connection to send data elsewhere like ErgData or EXR, etc.
People on alternate rowers like the RP3 or the SmartRow system I use may one day benefit from the work here if it extends beyond the Concept2. I have two data connections from my power meter, so one can go to my SmartRow app and another could go to a connection like this. Perhaps eventually C2 will update the PM5 to allow dual bluetooth signals as many cycling power meters have.

Hello, @Martin-Lillepuu .
Curious if ErgSync has been tested with non C2 rowers, such as WaterRower with the Bluetooth option installed on its computer. As I’ve (sort of) resolved the issue surrounding Varia radar units with the Race2, ErgSync + WaterRower is next on my list—but if anyone has any input before I head into things, I’m interested in your experience(s).

I believe you’re referring to the “commodule” that attaches onto the WaterRower S4 monitor.
https://www.waterrower.com/wr_us/waterrower-com-module.html
The other upgrade option for WaterRower is to get SmartRow, which is a replacement pulley that also sends metrics by bluetooth.
https://www.waterrower.com/wr_us/smartrow.htmlThe S4 / commodule gets metrics by measuring paddle rotations. Compared to the Concept2, this is quite a bit more “optimistic” in its pace. For example, a 2:00/500m pace might be something like 1:48/500m with the S4.
SmartRow is a power meter that measures the force you put on the drive, and uses the same power-to-pace conversion as the Concept2.
Neither method transmits exactly like the Concept2 though. In theory, this should all be covered by “bluetooth FTMS (FiTness Machine Service)” protocol, but in practice, apps like EXR needs to do different things to accommodate each method.
I use SmartRow and have not yet attempted to try to connect it to Suunto, as my current flow is to simply get the TSS load estimate from intervals.icu then edit my Suunto session report to change the TSS there to manual and replace it’s (lower) TSS with the result from intervals. I can try that in the near future, but that won’t be useful if you’re a ComModule person.
Edit: Today 11 April 2026, I attempted to connect SmartRow to Suunto and it failed to be found. Again, I wasn’t expecting this to work as the developer has only specified Concept2 at this time.

Yes, the ComModul is what I, at present, have on my rower. Well, technically, as the battery needs charging, and I’ve lost the cable. New one should be in later this week.
Good to know, though, that SmartRow is not (yet) connecting to ErgSync; saves me a few hundred that I’d rather not spend in the hopes it would work. Thanks for taking one for the team, @raven.
