I have a C-8 that is working well with many assorted devices. I paired an Aqara vibration sensor over a year ago with the Oh La LABS driver no problems.
I just bought two more Aqara vibration sensors via Amazon. One paired easily with the Oh La driver. The second one refuses to pair. I have tried dozens of times with various resets and sequences. I get to "Found a Zigbee device - initializing", "Finishing up, please wait ...", and then the "Having trouble pairing" notice.
It all sounds like a defective device. Anything else to try before I send it back? It feels like a personal defeat.
Here's what I had to do for Aqara contact sensors:
Aqara Door and Window Sensor
Pairing:
1. Reset by pressing button (on one of the sensor's short ends) for 3 seconds -- you should get 3 blue LED flashes.
2. In Hubitat, pair by selecting "Devices", "Add Device", "Find by device type", "Contact Sensor", "Generic/Other", "Generic Zigbee Contact Sensor", "Add", "Start Zigbee Pairing", THEN press the sensor's button quickly every 2-3 seconds until "Found a Zigbee device, initializing ..." appears (at which point, stop pressing the sensor's button).
So maybe combine my suggestions:
Remove the battery from the sensor for at least 10 seconds, then re-insert the battery;
Start pairing the sensor while within inches of the hub [maybe try picking the "Aqara Acceleration Sensor"]; and
Press the reset button quickly every 2-3 seconds until "Found a Zigbee device, initializing ..." appears (at which point, stop pressing the sensor's button) [I'm assuming your sensor HAS a reset button]
I think the key is pushing the reset button every two or three seconds during the pairing process. I vaguely recall doing that with the first sensor two years ago.
