ANT+ Cadence Sensor (Magnet Type) With Static Device ID

I need a ANT+ cadence sensor with a fixed ID. It needs to be persistent through power cycles, i.e through battery removal and replacement. It should be a magnet-sensing type, using a reed switch.

It seems common practice to randomize the ID at power-up. Probably so the manufacturer doesn't have to individually program each device on the manufacturing line. Makes sense but doesn't work for my project.

Any experience with this? Do you have a cadence sensor with ID which doesn't need to be re-learned after battery replacement? Thanks!

Never heard of this before and I've never had to re-pair my Wahoo cadence sensor when I replaced the battery.

Good to know. Are you using the Wahoo in ANT+ or BLE mode?

Edited my original post: It should be a magnet-sensing type, using a reed relay.

I haven't had to re-pair my Bontrager DuoTrap cadence/speed sensor. My Wahoo Tickr, which is paired to my phone with BT has a unique BT identifier (I actually have two, because I had lost one temporarily, and it has a different identifier).

I have no idea if it uses a reed relay or not.

A reed switch requires a magnet to trip it. You can hear the "pling" when a magnet comes within range. All of my ANT+ sensors (Wahoo, Cateye, and Garmin ) have a unique address to pair to.
