Im trying to pair an Srm Pc7 with an Ant+ Sigma speed sensor but I couldnt find it.
I tried to pair by searching for it with the Pc7 first, then I tried with the software; they even ask for the serial number and I tried to put it in automatic but Im not sure how exactly it works..?

Thanks in advance for any help!

Have you tried a fresh battery in the speed sensor? Also, what about magnet alignment? My suggestion would be to replace the battery then 'wake' up the sensor by passing a magnet over the specified area then try to pair the sensor.

i've used pc7/pc8 with various speed sensors, as long as the sensor uses the 'spd' profile it should work, and the ant directory suggest your sensor should be ok

have you put the pc7 in the correct mode? it needs to be set for ant+ speed sensor (speed sensor pairing display shows 'plus', not 'suunto'), the srm pc7 manual shows the process

Did you select the Pairing mode to "Plus" when you tried to pair it? This will enable the ANT+ pairing.

I tried years ago and couldn't make it work.
I still have that Sigma speed sensor here.
Please let me know if you're able to make it work!

if the sigma isn't working, i've used the vdo z-sender with pc7 https://www.thisisant.com/directory/ant ... r-z-sender not sure these are still available

the garmin hub mounted ones work fine with pc8, shoud be ok with pc7 too https://www.thisisant.com/directory/bike-speed-sensor1/ they are widely available
