Tacx Vortex Smart - can I connect to power meter?

Hello,

I have got one quick question - I use tacx vortex smart trainer but I also have (external) power meter.
Is it possible to use my power meter instead of tacx's power (it is 20 wats lower than my power meter readings)?

When I want to connect my device (power meter) is it not found on the list of devices.
I tried Rouvy and it works fine - it connets and reads data from power meter.

Thanks for any answers and suggestions
Slight smile
