I have no issues with them.
Have you reset them first?
Hold the reset button in until the LED flashes 3 times quickly (around 10 seconds) and let go of the reset button.
Then try pairing them again. Best to do this next to the hub.
You could try opening 2 hub windows.
In the first one go to
Settings -> Zigbee Details -> Zigbee Logging.
In the other window try pairing a device.
You should see the device details in the logging window.
If no device has been defined go into Devices -> Add virtual device and then manually input the device information and save.
See if this works and the device records events OK.
Actually in my experience, the best way to complete the pairing process is after you see the LED flash 3 times quickly (and "Initializing" shows up in the Habitat Hub browser window), continue to short-press the reset button every second or so.
The reason for this is that Xiaomi devices seem to go "asleep" immediately after the initial pairing, because when paired with a Xiaomi hub, the hub has all the info it needs, while on the other hand, Hubitat Hub still needs more information to complete the pairing process. Continuing to short-press the reset button will prompt the sensor to remain active.
