I don’t have one but, to support wxt9861’s statement, the zigbee2mqtt documentation for this device indicates three parameters it can report (and none of them is temperature):
@nu1mlock I have the original Conbee stick. My water sensors show the temperature as an attribute of the binary sensor in HA. Looks like this in Developer Tools - States:
So the leak sensor has a temperature sensor in it that the xiaomi hub doesn’t expose or how is deconz able to get this info? What other hidden features do xiaomi sensors have that aren’t available via their hub?
Sorry for the late reply everyone. It seems that the temperature reading that Phoscon reports hasn’t changed since I connected it, so I think we can safely dismiss the temperature reading from the water sensor.
