Tuya Water Leak Sensors - unknown in HA

Hi folks,

Zigbee-Water-Immersion-Sensor-Smart-Life-Leakage-Sensor-Water-Linkage-Alarm-App-Remote-Monitoring-Water-Leak.jpg_

I have 4 of these Tuya water leak sensors. If I connect via the Tuya app, they all work perfect and integrate with HA, detect water and do their job.

However, if I connect directly via Zigbee2MQTT they, all but one, say unknown as their status. Deleted, rebooted, restated, reset WiFi etc all to no avail.

Any ideas? This has stumped me!
