IR Record and Playback module

[BartE]

On special request i've created a IR (InfraRed remote) record and playback sensor.
This is based on the example IR sensor but now one can record a IR - signal from an remote and let your controller send the IR code on request. http://www.mysensors.org/build/ir

Up to 10 codes can be recorded and playback

Please note this plugin relies on a message type which is not yet available in the MySensors core (a pull request has been made)
This Arduino library https://github.com/z3t0/Arduino-IRremote/releases is used for decoding and encoding:

/**

 * between your home built sensors/actuators and HA controller of choice.
 * The sensors forms a self healing radio network with optional repeaters. Each
 * repeater and gateway builds a routing tables in EEPROM which keeps track of the
 * network topology allowing messages to be routed to nodes.

 * IRrecord: record and play back IR signals as a minimal 
 * An IR detector/demodulator must be connected to the input RECV_PIN.
 * An IR LED must be connected to the output PWM pin 3.
 * A button must be connected to the input BUTTON_PIN; this is the

@BartE

You are the king!

It's a bit late here now so I'll merge this things tomorrow.

[blacey]

@BartE, awesome! Your sketch should work perfectly with the IR Blaster. Perhaps you would be a good beta tester - where are you located?

[BartE]

@blacey this i've though about that too. (the IR-led i've tested with has a poor broadcast range)
I'm living in the Netherlands

[BartE]

Adding some Vera screenshots

[pete1450]

@BartE As I'm already using a sensor that I just control with light switch buttons in vera, I'd like to not have to add a IR receiver to the current board. Does this have the ability to let me just add the hex codes I already have?

Either way this is awesome.

[BartE]

@pete1450 i've added your feature request in version 1.1 of my plug in sketch You can add up to 240 RC HEX commands, from line 111, if you use an Arduino with enough memory. 40 will do with an Arduino UNO

I will update the Vera code as well in git
With Vera this luup code controlls the extra presets:
luup.call_action("urn:schemas-arduino-cc:serviceId:ArduinoIr1", "SendIrCode", {Index=15}, <device number>)
