Pairing sensors (example heart rate) / avatar stops = why?


Could you make it possible to add/pair your heart rate monitor without that your avatar suddenly stops? A few days ago, I entered an event and after 20 to 30 seconds (out of the pens) I noticed I had not connected my heart rate monitor. Went to the pairing screen and then your avatar looses all of its watt input and comes to a complete stop within a few seconds. Lost obvious connection with the bunch.

So … could you please make pairing your heart rate/cadence sensor available without your avatar has to stop?

Kind regards

Or they can just fix the bug where your Power,HR and Cadence does not show while in the pen. If that worked you would have seen that your HR is not showing and you could repair everything.

So back to your question = Why?
My thinking is that they did that because people would switch trainers mid ride to get ahead in races. They would switch for smart trainers to Z power for the climbs and then back.

Yes that reason would make sence. Perhaps they can modify it that only when you pair a new power meter/other source power meter, your avatar stops.

Bringing up the Zpower, brings also up another issue I have with Zwift. I always ride with 100% resistance, and I expierence this as a handicap with those 20%-40% riders when inclines suddenly drops (example 2nd corner on the FWD KOM). When riding 100%, your power always drops, something the 20-40% rides do not have (so they have an advantage). Or am I mistaken?

There should be events (definitly the Fondo’s), where everyone rides at a certain resistance (read 100%). #Plain leveling field.

If you are running at 100% then you should be ready to change gears quickly like in real life. That is the idea of 100% to get closer to real life. The opposite is true for people running at 20% if there is a sudden incline they don’t feel it and need to change gears to up the power.

If that happen than we also need to limit the gears people use. Running a 56 48 chain ring vs a triple 40 30 22 is very different.

When an ANT+ dongle goes into pairing mode is loops through all the available channels (1 to 8) looking for devices and assigning channels. I do not think it is technically possible to only re-pair one channel. See page 9 of this doc

This is why a weak battery in a HRM can cause a drop out in your power source - because if the dongle goes into pairing mode it may drop and re-pair the trainer as well. Sometimes it is quick to re-pair, and not noticed because of 3 second power averaging. Other times it takes a while and you’ll see a drop in power. Some dongles pair quicker than others. And as you pointed out, entering the device pairing screen is like slamming on the brakes.


Hi, thanks for the explination!
So better double check it before then!
