Thanks Werk. I moved away the RX, tried a different room as well, and also removed the RX antenna as suggested. When I reboot the board, I still see 000 for more than 2 min.
I will let it run during the night and will see.

What about the temperature sensor? Could it be it to prevent the TX to work properly?

Thanks.

The inside temperature sensor is read only after the initialization process, so for now we should focus in discover why the RX unit is not receiving data from the three main sensors.

Next things to check / try:

Check if you have defined the correct board version in the RX software

// ---- Define your RX board, main version number
#define Board_Version 6 // 6 for all RX boards v6.xx, 5 for all RX boards v5.xx, 4 for all RX boards v4.xx

I think your RX board is a v4.xx or a v5.xx

Try to run the RX unit in test mode.

// --------------------------------------------------------------------------------------
// Test Mode : Never run a live system in test mode
// --------------------------------------------------------------------------------------
#define TestMode false // false or true

Do you see any data from the outside sensors on the LCD display?

Continue running the RX unit in test mode, and on the TX software enable sending just one type of sensor at a time...

// --------------------------------------------------------------------------------------
// Define which data this unit will send. 0 = Not send this data, 1= Send this data
// --------------------------------------------------------------------------------------
#define ID0 1 // Temp/Hum Data
#define ID1 0 // Not Used
#define ID2 0 // Wind data
#define ID3 0 // Rain data
#define ID4 0 // UV / SolRad data
#define ID5 0 // Hardware Status - System Temp, Battery Voltage etc
#define ID7 0 // Send Soil & Leaf Temperature Data
#define ID9 0 // Send Soil & Leaf Moisture / Wetness Data

Repeat procedure for Wind, and Rain, one at the time. Is the TX led on the TX unit blinking for each type of sensor?
Could you please post your Config_RX.ino and Config.TX.ino files?

Another important thing. If you are using the Inspeed E-Vane, the JP2 jumper on the TX board should be keep open.
