Turns out that Aqara is now shipping a new generation of sensors, likely based on the Zigbee 3.0 specification. See the announcement end of last year: New Aqara T1-series Zigbee 3.0 devices finally available - Lounge - Hubitat
Which can be recognized by the Zigbee Z logo printed on the side / back of the device.
Like with this Aqara water leakage sensor: Homey v5.0.0 (Stable Release) - #191 by TedTolboom
If your inclusion of a sensor results in it to be added as a Generic Zigbee device, please send me a note with the details.
