int requestedLevel = message.getInt();

It works like a charm now Thank you

@AcidUK Perhaps I'm an earlier generation of monkey then you are, because I can't get it to work properly Could you please tell me what steps did you take to get this working? I've changed MyMessage.cpp to this:

/*
int16_t MyMessage::getInt() const {
	if (miGetPayloadType() == P_INT16) { 
		return iValue;
	} else if (miGetPayloadType() == P_STRING) {
		return atoi(data);
	} else {
		return 0;
	}
}
*/

int16_t MyMessage::getInt() const {
    if (miGetPayloadType() == P_INT16) { 
        return iValue;
    } else if (miGetPayloadType() == P_STRING) {
        // Null terminate string according to message length to prevent reading old bytes from data
        char* ca;
        ca = (char *) data;
        ca += miGetLength();
        *ca = '\0';
        
        return atoi(data);
    } else {
        return 0;
    }
}

Then I reflashed gateway and sensor and the result is the same as before:

read: 0-0-2 s=0,c=0,t=3,pt=0,l=2,sg=0:35
351mableLED
Changing level to 100, from 0

Am I missing something besides my programming skills ?

I'm getting the same behavior with latest dev (as of 27.12.2015). I'm using ESP8266 mqtt client gateway.
