Chris, perhaps you can confirm, but I think we have to take Polar's word literally when the release notes say "Support for Kéo Power Bluetooth® Smart"; in particular, I don't think the 1.1.70 firmware (or possibly the current Flow web site) truly supports third-party power meters. For this morning's commute, I tried a PowerTap PowerCal: https://flow.polar.com/...ng/analysis/29346478
The watch did ask me if I wanted to update training pages, and when I agreed, it added power data to one of the pages. However, the Flow web site doesn't show any power data on the graphs. It does, however, list an average and max power in the summary. (The average is at least 100 W too high, FWIW, and I'm certainly not generating a maximum power of 2 kW. I'm not that hardcore when commuting, but this could be mostly an issue with the PowerCal which is notoriously spiky.) Other than those two numbers, nothing. I didn't look at the watch during the ride, but I'll try and glance at it on the way home this afternoon to see what real time data is there.
Bottom line, I think that power support, at least for third-party meters, isn't fully baked yet. Not a huge deal for me since I'm really waiting for Viiiva support (both my road and tri bikes have Quarqs) which wasn't advertised until a later release anyway (but is coming soon I hope).
