I've had this once or twice, but in my Edge 810. Bad calibration, then disappears. Have to turn off power meter detection and then back on again, find the unit then Calibrate again.
4iiii app is garbage, don't bother. -
I had this, and ended up having to send back to 4iiii for a replacement unit. They did me a decent discount as it wasn't too far out of warranty

Anyone had an issue with a 4iiii single crank powermeter not being able to calibrate? I can connect to the device on my wahoo, but the numbers it gives are way lower than reality (by c200w). The 4iiii app won't connect. When I try to calibrate it comes up with a failure message. Change of battery hasn't made a difference. No crash damage or water ingress as far as I know/can tell
