I tried using Zwift with a non-supported mag trainer. Even with cadence and speed sensors, I couldn't move fast enough to get away from runners no matter how fast I pedaled.
A few months ago I bought a used Kurt Kinetic fluid trainer (wish I'd splurged for the Rock and Roll!), and spent $50 for their iNride sensor. It has a known power curve and the sensor provides a power output that lets me ride at speed in Zwift. Granted, it doesn't provide resistance changes to terrain, which is why I call it my "HalfSmart" trainer... I paid $90 for the used trainer, $50 for the ANT+ sensor. A few bucks for an ANT+ USB dongle, a 15 foot USB extension puts the ANT+ dongle at the trainer for the best possible signal quality. I use a laptop presently for Zwift, then HDMI cable to my 50" TV. And my phone on the bike for the Companion app.
