Hi, zitoune

Please check the user config options in the TX software.

For the SH21 it should be:

Code:

// -------  Define type of Temperature Humidity for Sensor 0 and Sensor 1 --------------
#define TH_Sensor0  0      // 0 for SHT2x sensor, 1 for HTU21 sensor, 9 for Not Used
#define TH_Sensor1  9      // 0 for SHT1x sensor, 1 for DHT22 sensor, 9 for Not Used

For the DHT22 it should be:

Code:

// -------  Define type of Temperature Humidity for Sensor 0 and Sensor 1 --------------
#define TH_Sensor0  9      // 0 for SHT2x sensor, 1 for HTU21 sensor, 9 for Not Used
#define TH_Sensor1  1      // 0 for SHT1x sensor, 1 for DHT22 sensor, 9 for Not Used

You also can keep both connected:

Code:

// -------  Define type of Temperature Humidity for Sensor 0 and Sensor 1 --------------
#define TH_Sensor0  0      // 0 for SHT2x sensor, 1 for HTU21 sensor, 9 for Not Used
#define TH_Sensor1  1      // 0 for SHT1x sensor, 1 for DHT22 sensor, 9 for Not Used

You should also check/define in the RX user config options which one will be your main temperature / humidity sensor.

Code:

#define MainOutTH_Sensor 0   // 0 for sensor type SHT21 or HTU21D, 1 for sensor type SHT1x or DHT22
