Blynk, NRF24l01 and esp handling multiple sensors

On serial to wemos, I can read the sensors correctly

This surprises me.
Have you edited the Settings.h file of the Edgent example? If not, then you will have a conflict here:

@bogdancoroi

#define D3 0 // SI

because GPIO0 is used as the BOARD_BUTTON_PIN for Edgent.

Troubleshooting Edgent Dynamic Provisioning Problems

There seems to quite a bit of confusion about how the dynamic provisioning process works in the Edgent sketch examples, and how to re-provision a device with new WiFi credentials. Many people omit to configure the board type correctly in the sketch, and this also causes problems. Here’s a guide to how the process works, and the things to watch out for… Overview You start by creating a template, preferably in the web console (https://blynk.cloud/) This gives you the BLYNK_TEMPLATE_ID and BLYNK…

In addition, I don’t understand how your Wemos is meant to distinguish between temperature and humidity readings coming from your RX2 board. The board is pushing these readings out one after another at half second intervals, and your Wemos is looking for them at 1.5 and 2 second intervals, but there is no synchronisation (and no way to establish synchronisation) between the RX2 and Wemos boards.

I’d suggest that you change this part of your sketch…

@bogdancoroi

void myTimer(){
  radio.read(&temp1, sizeof(temp1));
  Blynk.virtualWrite(1, temp1);
  Serial.println(temp1);
}
void myTimer1(){
  radio.read(&temp2, sizeof(temp2));
  Blynk.virtualWrite(2, temp2);
  Serial.println(temp2);
}
void myTimer2(){
  radio.read(&humidity2, sizeof(humidity2));
  Blynk.virtualWrite(3, humidity2);
  Serial.println(humidity2);
}

to this…

void myTimer(){
  radio.read(&temp1, sizeof(temp1));
  Blynk.virtualWrite(1, temp1);
 Serial.print("temp1 = ");
 Serial.println(temp1);
}
void myTimer1(){
  radio.read(&temp2, sizeof(temp2));
  Blynk.virtualWrite(2, temp2);
  Serial.print("temp2 = ");
  Serial.println(temp2);
}
void myTimer2(){
  radio.read(&humidity2, sizeof(humidity2));
  Blynk.virtualWrite(3, humidity2);
  Serial.print("humidity2 = ");
  Serial.println(humidity2);
}

so you can better understand the data that is appearing in the Wemos serial monitor.

I would suspect that you will need to send one string of data from your TX2 device which includes both temperature and humidity, then parse the results to give you the separate values.
