Hi,
recently, I have been having issues with my JetBlack Volt trainer. ERG mode is fine, but sim mode is not working correctly. Power readings seem ok (though slightly delayed), but the resistance is all over the place and does not relate to the current gradient in the game at all. Sometimes, the resistance is increased incredibly when going downhill, sometimes after riding on a flat for some time. Takes a lot of the fun out of races and any riding that is not an erg workout.
The logfile is full of the lines below. I am using the Zwift Play controllers with the current firmware. Volt firmware is the most recent one too.

Other software can control the trainer just fine, this only happens on Zwift.
