Here's the output of the following commands:

'v' - send current version
'w' - send current weather sensor values
'p' - send current weather sensor values (pretty printed)
't' - send sensor read durations
'c' - send sensor configuration settings

{"version":"1.12"}

{"MLX90614":{"init":false}}

{
"MLX90614": {
"init": false
}
}

Using an I2C scanner I can see that the sensor is connected:

Was able to find a MLX90614 sketch for a Wemos and the sensor works !!! However I cannot make it work with the weatherradio.ino code

Hm. strange. The only problem I remember was having a wire clock set too high. But the wire clock is only changed if the OLED module is activated in weather radio.

Check the configuration of OLED_WIRE_CLOCK_SPEED in config.h. I noticed that it should not be higher than 100kHz:
#define OLED_WIRE_CLOCK_SPEED 100000L // set to 100kHz if using in combination with MLX90614

I do not use an OLED, I've commented that entire section out.

From all the tests I've done, my board and sensor are working using some simple code like the one I've posted earlier, however with the weatherradio.ino it clearly does not work. One think to mention is that it is the only sensor connected.

That’s awkward, there must be something special in your setup. What board do you use?
I think the only way is to add debugging messages into the mlx code of weather radio, especially around mlx.begin(). Maybe out of a strange reason this part never gets reached.

I have the WeMos D1 Mini V3.1 (a real one and not a clone).
 

As I mentioned previously, the sensor and board works well with a simple code for the MLX

It's FIXED !!!

The code needs to be changed from:

in fact, just done another test and the line "return (error == 0);" can be commented out completely.
But it's quite slow to update the temperature I must say.

Many thanks for your feedback. I resolved it slightly different. The main bug was that the status was never updated once the initialization was successful:
/**    mlx.begin() always returns true, hence we need to check the I2C adress */
bool isMLX90614Present() {
  Wire.beginTransmission(MLX90614_I2CADDR);
  byte error = Wire.endTransmission();
  mlx.begin();
  mlxData.status = (error == 0);
  return (mlxData.status);
}
 
void updateMLX() {
 if (mlxData.status || (mlxData.status = isMLX90614Present())) {
   mlxData.ambient_t = mlx.readAmbientTempC();
   mlxData.object_t  = mlx.readObjectTempC();
 }
}

Could you please check if this works for you?

thanks for the update, that however breaks everything. Nothing comes out from the W/V/T etc commands..
correction:
I had selected the wrong baud, hence nothing came out.

However, it's back to the original issue:
Weather Radio V 1.12
{"MLX90614":{"init":false}}
{}
null
