Thanks for this cool project, wishing all a good 2018!

Hi Tekka,

Happy 2017! Thanks for the update, can you upload a 8Mhz precompiled bootloader? (and update boards.txt)

I'm curious is there a changelog since last version?

Hi all,

First of all my compliments for this fantastic framework, I'm new here and I was trying to improve the wheel many times but using "mysensors" feels like the right way to do things (tm).

I like to connect different things to my domotica system, this time I'm trying to create a 433Mhz sender. I know there are some examples but they don't seem to fit my needs.

What I like to do is create a general 433Mhz sender based on the NewRemoteTransmitter library, the parameters to the sendUnit function should come from the controller (mind the 24byte limit, parameters should include: address,unit and payload all encoded in a single VAR1 payload)

I have some questions, perhaps one of you can help me?

• Is VAR1 for the payload a good choice?
• What is the best way to tranport a multi value payload? (address,unit,payload)
• 433Mhz also supports DIM levels, ranged from 0 to 15, is there an easy method to scale this from 0 to 100?

Many questions for a new user I know, hope to see some feedback

current example code

// 433Mhz transmitter for mysensors.org

#include <MySensor.h>
#include <SPI.h>
#include <NewRemoteTransmitter.h>

#define SN "RF433Sender"
#define SV "1.0.2"
#define TRANSMITTER_PIN 8
#define RF433_CHILD_ID 1

MySensor gw;
MyMessage msg(RF433_CHILD_ID, V_VAR1);

void setup()
{
  // Attach method for incoming messages
  gw.begin(incomingMessage, AUTO, true);

  // Send the sketch version information to the gateway and Controller
  gw.sendSketchInfo(SN, SV);

  // Register all sensors to gw (they will be created as child devices)
  gw.present(RF433_CHILD_ID, S_IR);
}

void loop()
{
  gw.process();
}

void incomingMessage(const MyMessage &message) {
  if (message.type == V_VAR1 ) {
    unsigned long address = 231337; // TODO hardcoded
    int unit = 0; // TODO hardcoded
    bool payload = message.getBool();

    /*
    Serial.println(address);
    Serial.println(unit);
    Serial.println(payload);
    */

    NewRemoteTransmitter transmitter(address, TRANSMITTER_PIN, 260, 3);
    transmitter.sendUnit(unit, payload ? 1 : 0);
  }
}

great to hear! Please let me test
