Hi Jim,

On the software package for the WD Pro4 Weather Display, there is folder called pinout, there you can find an image with the pinout for the T/H sensor.

Regarding the supported sensors, please give a look at the software user configurable options:

Code:

// --- Define type of Local TH sensor
#define INSIDE_TH_SENSOR     9      // 0= BME280, 1= HTU21D, 2= SHT21, 3= SHT31, 9= Use Main Station TH sensor

Preferably use the 3.3V versions. For the WD, I would recommend the SHT31, quality/price is the best.
