I reported this bug around 6 months ago and still no word on a fix!
When using the Quarq Dzero power meter as the power source when I stopped pedaling the watts would stay at whatever they were before I stopped pedaling. I noticed this on a downhill when I jumped to 500w to get my speed up and then coasted down the hill at 0 rpm. The game thought I was doing 500w the whole way!! This is 100% repeatable as I later tested.
If i let my Kickr control the power then there is no problem.
What the hell is going on?
In the Zwift riders group on facebook I was told " we’re actually in the process of figuring out which BLE devices are still doing this, as we’ve already addressed the issue on a number of speed sensors and some power meters. Can you please open a support ticket for us, so we can get your logs? We’ll get your device added to our database to be addressed as well. Thanks!"
I took a break from Zwift for a while and low and behold 6 months later the bug is still there. The original ticket I created 6 months ago is still open so presumably it is still being investigated? what is going on? I replied on my ticket almost 2 weeks ago and haven’t received any kind of reply. Don’t really like being totally ignored when this is a service i’m paying for!
