Hi,
I’m trying to pair the ThirdReality Smart Soil Moisture Sensor (3RSM0147Z) with deCONZ/Phoscon on Home Assistant. I’m running deCONZ version 2.32.5 with a ConBee II stick.
The sensor does join the Zigbee network - I can see it in the deCONZ network map as an End Device on battery. The Cluster Info shows the correct clusters: Temperature measurement (0402), Relative humidity measurement (0405), Soil Moisture measurement (0408) and Power Configuration (0001).
However, the Manufacturer and Model Identifier both show as “unknown” in deCONZ. Because of this, deCONZ cannot match the device to its DDF (Device Description File), even though support for the 3RSM0147Z was added in deCONZ v2.29.3.
The sensor never appears in Phoscon or in Home Assistant.
I tested two brand new sensors and both have the same issue.
See 
Please assist.
Cheers,
Jaap
