Limited options <sigh>
If the sensor drop-outs are causing Zwift to be unusable…
As far as I can make-out, the Aleno estimates a lot of the usual data while using a manual resistance set up. I would change the power Aleno estimates and sends to Zwift via Bluetooth, with a separate ANT+ set up, basically using the trainer as a ‘classic’, allowing Zwift to do the power estimation (zPower) but giving Zwift actual cadence and heart-rate data…
The only caveat I can envisage may be the Zwift power-curve for the trainer, I’m not sure if there is a specific component to choose from.
Get you an ANT+ dongle for the Mac along with ANT+ speed/cadence/heart-rate sensors.
When not using Zwift the original Bluetooth component within the trainer can be used.
The ANT+ set up can be transferred to another computer and trainer should you decide to update in the future.
Unfortunately the trainer is going to move around due to its weight, that is, lack of it.
Not much help, I know
