Reporting wifi signal strength Topic is solved

[djdehaan]

I am trying to report from an Arduino ESP8266 using MySensors (2.0.0) to Domoticz (3.4834) the wifi strength. So this is what I added to the sketch:

Code: Select all

MyMessage Msg_DB(Sensor_DB, V_VAR1);

Code: Select all

present(Sensor_DB,S_CUSTOM, "Wifi dB");  //wifi db

Code: Select all

void Sync_DB() {
  int i = WiFi.RSSI();
  send(Msg_DB.set(i));
}

The Sync routine is called every minute, but never appears as a device in Domoticz. It does appear in the hardware section as one of the children of the MySensors gateway. But it seems like it never gets any data.

I also tried using: V_LEVEL and S_SOUND, but also no device did appear.

Can anyone help me how to solve this?

The entire Sketch (the includes are in the main sketch).

Code: Select all

const byte Sensor_HEART = 1;
const byte Sensor_Relais[] = {2,3,4,5,6,7,8};  // 7 totaal
const byte Sensor_VIN = 9;
const byte Sensor_VBATT = 10;
const byte Sensor_VOUT = 11;
const byte Sensor_PWR = 15;

//const byte Sensor_TEMPHUM = 16;
const byte Sensor_ESP = 20;
const byte Sensor_DB = 19;


MyMessage Msg_HEART(Sensor_HEART, V_STATUS);
MyMessage Msg_Relais[7];
MyMessage Msg_VIN_V(Sensor_VIN,V_VOLTAGE);
MyMessage Msg_VIN_A(Sensor_VIN,V_CURRENT);

MyMessage Msg_DB(Sensor_DB, V_VAR1);

//MyMessage Msg_TEMP(Sensor_TEMPHUM, V_TEMP);
//MyMessage Msg_HUM(Sensor_TEMPHUM, V_HUM);





void setupMySensor() {
  for (byte i=0;i<7;i++) {
    Msg_Relais[i].sensor = Sensor_Relais[i];
    Msg_Relais[i].type = V_STATUS;
  }
}

V_VAR are variables only used internally, for instance when you made a metering sketch, you can store/retrieve the last counter value

You want to use the V_TEXT

[djdehaan]

Thanks Gizmocuz. It works now with V_TEXT en also with V_LEVEL and S_SOUND.

Also I found out that if you want to send a String from Arduino, you have to convert it to a chararray first, otherwise it will come through as a number.
The Sync_ESP is my original post did not work, but this does:

Code: Select all

void Sync_ESP(String s) {
  byte b = s.length()+1;
  char c[b+1];
  s.toCharArray(c,b);
  send(Msg_ESP.set(c)); //"WV1_c7_db-55"
  myLog+=s;
}

And finally, a great help indeed in understanding what happens, is the MYScontroller tool:

A must have for anyone playing around with MySensors.
