Bring the device next to the hub and retry
Check hub firmware version
Replace the battery before pairing

Step-by-step fix

Remove the device from any previous hub

Reset the device to factory state

Put the hub in add-device mode and pair within one metre

Move the device gradually to its final position

If it drops at distance, add a mains-powered Zigbee router between hub and device
