810 not pairing with cadence and speed sensors.

I have been trying to get my 810 to pair with a pair of Garmin speed and cadence sensors. I have followed the instructions in the manual, but I get device not found.
The sensors do blink green for about 5 seconds after turning the pedals.
Garmin support do not seem to be able to solve the issue. Is there any one who has had this problem and been able to resolve it.

The sensors sleep when they have not turned for while - the green lights indicate they are awake. You need to search for them on the device whilst you are turning the sensors (you can spin them in your fingers if that is easier).
That said, I presume Garmin support would already have suggested that! If the lights are blinking and the device is still not picking them up, you may have a bigger problem...
Also, have you got sensors on another bike too?(which your garmin normally pairs to) If so it may be Trying to pair to those instead. I had to set up a new bike profile on the Garmin with the new sensors.
When i first had my 520, i had awful issues pairing, i thought it was sensor batteries or even the sensors (speed or cadence) what seems to have fixed it, is f/w updates, might be worth checking you ve got the latest? 5.10
HR was never a problem.
make sure batteries are ok too, i had to swap out the one on the cadence sensor from new, as its v+ was v low

I could not do it after I had set up the 810, using Garmin instructions failed.
I had to reset the 810 and during the setup phase it came to the search option, pairing at this point worked. I then went on to setup the 810,
