Local sensor (no radio)

[shabba]

I have a RPi 2 controller connected to a uno that has the radio (serial GW). I also have a arduino mega that controls all my heating zones in the house (11). Right now the mega is just spewing out debug on the serial port but I would love to connect it to the RPi and integrate it into my mysensors network. Is there any libraries for doing this or has anyone done similar? I don't want to add a radio to the mega as it is sitting right beside the controller.

Thanks!

Depending on how curious you are, and how advanced a setup you want, You could make a mockup that emulates the serialport protocol, it should be pretty easy to do. Or you could make a nodered flow, that picks up data from your mega, and remaps it to mysensor protocol, and then inject that into the data stream in to you controller of choice.

Yeah - I guess I was hoping someone else had pioneered it
It is interesting though. I'll try and send the wife and kids away for a week!

You should have a look at the "gateway-refactoring" branch. Over there it is possible to create a node without radio.

A serially attached gateway motion sensor would look like this:

// Enable debug prints to serial monitor
#define MY_DEBUG 

// Enable serial gateway
#define MY_GATEWAY_SERIAL

#include <MySensor.h>  

#define CHILD_ID 1  
MyMessage msg(CHILD_ID, V_TRIPPED);

void setup()  
{ 
  sendSketchInfo("Motion Sensor", "1.0");
  pinMode(DIGITAL_INPUT_SENSOR, INPUT);     
  present(CHILD_ID, S_MOTION);
}

void loop()  
{ 
  boolean tripped = digitalRead(DIGITAL_INPUT_SENSOR) == HIGH; 
  send(msg.set(tripped?"1":"0"));  // Send tripped value to gw 
  sleep(INTERRUPT,CHANGE, SLEEP_TIME);
}

And what or how do you register this sensor in domoticz?

Sorry, haven't used Domoticz myself.
