Hi Graham

From what I read, I'm sure you are in the right direction and both units are working. Your "gotchas" just lead you to know more about how the system works

At this stage I will be using the SHT22, it's currently connected just for testing.

For this sensor, please make this changes:

Config_TX.h

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

Config_RX.h

Code:

// ---- Lets define the source or type of our main outside sensors
// ---- If you have all the sensors connected to only one TX board, always select Unit 0 as source
// ---- Define the source of your main Temperature / Humidity sensor
#define TH_OutUnit       0   // 0 for Temp/Hum sensor connected to TX_Unit 0, 1 for Temp/Hum sensor connected to TX_Unit 1
// --- Define your main outside Temperature / Humidity Sensor
#define MainOutTH_Sensor 0   // 0 for sensor type SHT21 or HTU21D, 1 for sensor type SHT1x or DHT22

I had only configured ID0 and ID5 at this stage. I could probably mock these up just for testing.

When you said that the TX Led is blinking more or less at 20 sec intervals, I thought something like that.

At this point, you can continue testing your RX and TX units, even without the wind sensor and rain gauge attached to the TX unit.
At least activate ID0, ID2 and ID3, and the RX unit will happily pass the initialization phase, without having to run it in test mode.
