The XOSS speed/cadence induction sensor works fine. It has mounts for either the crank arm or hub. I've used it both ways. Data pretty well matched my older Wahoo wired-together speed/cadence sensors with magnets.

The only fiddly part is the battery swap trick for switching the XOSS between speed and cadence modes. It's easier to grasp the trick by checking YouTube videos.

I'm guessing other induction type speed/cadence sensors switch modes the same way -- remove and replace the battery. But the XOSS battery cover makes it a bit fiddly. They probably save a little weight over the magnet type sensors.

I recently paid $10 for a new/old stock Wahoo Bike Pack just for the wired together speed/cadence magnet sensor unit. It's a 2012 era doodad that preceded Wahoo computers. It includes a protective case for an iPhone 3/4 series that adds ANT+ capabilities, and a handlebar/stem mount. I use the adapter and iPhone only on the indoor trainer. The iPhone battery won't last a full 50-60 mile ride, but indoors I can run an external USB battery for marathon sessions. Not worth the original MSRP of around $150, but worth $10 for the sensors, if you don't mind the old style sensors that used magnets on the rear wheel spoke and another on the crank arm, using zip ties to hold 'em on.
