Yes, I have capacitor on both radio.

I am still trying to make it work. I uploaded on my temp/humidity sensor the code of the relay actuator (sketch:47534). I just updated this line to set the ID=10:

gw.begin(incomingMessage, 10, true); //Set ID=10 instead of AUTO

On the serial window of the temp/humidity everything looks fine:

read: 0-0-10 s=0,c=1,t=3,pt=2,l=2:18
send: 10-10-0-0 s=0,c=1,t=3,pt=2,l=2,st=ok:18

But on my node (gateway) I still have error

send: 0-0-255-10 s=0,c=1,t=3,pt=2,l=2,st=fail:18
Error sending message

The code is now as below:

  // Alway process incoming messages whenever possible
  gw.process(); //Read radio message, and display in serial window
  
  //Create a test messge to send to node
  MyMessage msg;
  boolean ok = false;
  msg.sender = 0;
  msg.destination = 10;
  msg.sensor = 0; //To be set later
  msg.type = S_LIGHT;
  //mSetRequestAck(msg,0); //No ack
  //mSetAck(msg,false);
  //mSetCommand(msg,S_LIGHT);
  msg.set(18);
  ok = gw.send(msg, true);
    if (!ok) {
      //errBlink(1);
      Serial.println("Error sending message");
    }
    else  
      Serial.println("Success !!!!");
  delay(5000);

Hello,
Thanx to your help, it is now a few months I have a temp/humidity MySensor with the data updated in my eedomus domotic box.
Now the next challenge is to make a relay actuator. I did not buy the hardware yet, thus I wish to validate the transfer of the message from the box->gateway->sensor.

• I have made the first step getting the command (O=Off, 1=On) from my eedomux box to my gateway node.
• Now I am trying to send the message from gateway (ID=0) to my existing temp/humidity sensor node (ID=10). I have written the following code:

void loop() 
{
  // Alway process incoming messages whenever possible
  gw.process(); //Read radio message, and display in serial window

 //Create a test messge to send to node
  MyMessage msg;
  boolean ok = false;
  msg.sender = 0; //0=gateway ID
  msg.destination = 10; //node ID
  msg.sensor = 2; //To be set later: CHILD_ID_HUM 0/CHILD_ID_TEMP 1
  msg.type = 1; //set=This message is sent from or to a sensor when a sensor value should be updated
  mSetRequestAck(msg,0); //What is the difference with the one after ?
  mSetAck(msg,false); //For now no ack, later it would be better to get one
  mSetCommand(msg,S_LIGHT);
  msg.set(1);
  ok = gw.send(msg);
    if (!ok) {
//      //errBlink(1);
      Serial.println("Error sending message");

For now the gw.send returns not OK.
Am I doing right by creating the message manually or is there a better way to do ?
What is wrong that the message is not sent ?

Thank you, that seems to perfectly answer my need.
However I have one question: I will use the MyGateway::begin which takes void (*inDataCallback)(char ) parameter which seems less convenient to use than the void (_msgCallback)(const MyMessage &) parameter of the MySensor::begin.
Why is it like this ? Would it be not more convenient to have a callback with a MyMessage ?

Hello,

Here is the status on my project to connect my eedomus controller to MySensors:
I am limited to make HTTP request to update some virtual state on my eedomus box.
I build an Arduino (mega) with an Ethernet shield to validate I can update a virtual state on eedomus.
I built a MySensor serial gateway with a temp/humidity sensor. Using hard-coded sensor's ID, I managed to get temp/humidity on the gateway.
I am now stuck to make both working together.
I have my sketch gateway: MySensorsGateway (http://www.mysensors.org/build/serial_gateway) using the library MyGateway and I have the library Ethernet.
In MySensorsGateway, I can use Ethernet library but I cannot access the message received.
In MyGateway library, I can view/display the message received but I cannot use Ethernet library.
I would like to access received message in MySensorsGateway in order to forward them by HTTP requests to my eedomus controller.
Can you point me in the right direction ? Some sample code would be great.

Hello,

I asked for support eedomus team and in eedomus forum but got no reply at all.

eedomus box has an USB port. I wonder, if I build a serial gateway (http://www.mysensors.org/build/serial_gateway) and connect the USB port to my eedomus box, is there any chance my box will recognize it ?

I think I have no possibility to build a plug-in for eedomus as Connected Objects does not provide any kind of API to extend the features of their box.

Hello,
I just discover MySensors. It seems eedomus is not currently supported. Is there a chance I could integrate my eedomus controller with MySensors ?
Any hint/advice on how to proceed would be warmly welcomed.
