In the serial monitor, I see: "RF95 init done" and "DS2482-100 not detected" because I haven't connected the Soil Leaf interface yet.

Hi,

If the DS2482-100 chip is installed it should be detected even if Soil Leaf interface isn't connected.

In your Config_Options you have defined the use of both TH_SENSOR0 and TH_SENSOR1 with a sensor STH31 type, that is ok, but both can't be on the same I2C address (0x44)
This info is stated on the code right above the config settings for TH_SENSOR1

Code:

// -------------------------------------------------------------------------------------- // Define type of Temperature / Humidity sensor used as Sensor 1 // IMPORTANT - If two I2C sensors (SHT31 or SHT2X) are used, each one must have its own I2C address // --------------------------------------------------------------------------------------
