Relay_Actuator add second relay?

[Cliff Karlsson]

I have just got the 110v-230v AC to Mysensors PCB board working but I want to add another raley to PIN 5, how do I do that?

     Serial.println(message.getBool());
   } 
}

But first of all I dont know what do do with the button, I want to be able to control one of the relays with the button. Second is this part at the end:

void receive(const MyMessage &message) {
  // We only expect one type of message from controller. But we better check anyway.
  if (message.isAck()) {
     Serial.println("This is an ack from gateway");
  }

  if (message.type == V_LIGHT) {
     // Change relay state
     state = message.getBool();
     digitalWrite(RELAY_PIN, state?RELAY_ON:RELAY_OFF);
     // Store state in eeprom
     saveState(CHILD_ID, state);
    
     // Write some debug info
     Serial.print("Incoming change for sensor:");
     Serial.print(message.sensor);
     Serial.print(", New status: ");
     Serial.println(message.getBool());
   } 

How would I adapt that to the usage of two relays?

@Michel--
Many Kudos.
i tried your code modified for my single relay and button pushes successfully trigger the relay! I'm also reading status correctly in Vera.

I am having some trouble controlling the relay from Vera. It appears as if the msgs from Vera aren't a) being received by the node, b ) not interpreting the node

I'm new to programming and not too sure of where to look.
Any Suggestions?

I wanted to clarify that i got it working.

I was browsing through the MySensors API and came across the Processing incomming messages section.

What I interpreted out of the explanation there is that a node acting as a relay actuator NEEDS to be configured as a repeater node in order to run the code needed to interpret incoming messages.

I kept removing the parameters in gw.begin() to make the node a non repeater because i have such a short range between my gateway and the node. Once i updated my sketch to configure the node as a repeater... BOOM! we're up and running!

I did notice when configuring this node in Vera, that i needed to cycle the sensor 3 times to be fully operational. My steps were as follows:

1. Delete node and light objects from vera. then Reload Vera.
2. Run inclusion on gateway
3. turn on node
4. power cycle node to auto configure light object in vera to display on/off buttons and get sketch name and node details.
5. power cycle node one more time. this seemed to get the sensor and Vera to sync up and report state properly back to UI5. after this everything was working wicked smooth.

Now i need to work on adding in my DIY soil sensor in.

I hope my resolution may help any other newbies in the world of this wonderful MySensors journey!

Cheers

@rchamp

Calling gw.process in the loop and not sleeping should be sufficient for a relay. It shouldn't have to be configured as a repeater.

[rchamp]

@martinhjelmare

thank you. i corrected my code to not enable as a repeater
