I am attempting to pair a new Third Reality Smart Soil Moisture Sensor Gen2 with Home Assistant using ZHA. The device refuses to complete the interview or show up in the ZHA UI. To troubleshoot, I hooked up a USB-to-UART adapter to the serial debugging lines (TX/RX) on the sensor board running at 200,000 baud to see what the hardware is doing during the pairing window.
Logs are here.
