@Sparkman, hero member I get it now. Thank you!

@Spakrman alright, say I have one of those Epson projector http://www.remotecentral.com/cgi-bin/codes/epson/lcd_projector_no_touchdisc/
how does one go about sending say POWER command

0000 0071 0000 0002 0000 00AA 0000 0040 0000 0040 0000 0015 0000 0015 0000 0015 0000 0015 0000 0015 0000 0040 0000 0040 0000 0015 0000 0040 0000 0015 0000 0040 0000 0015 0000 0040 0000 0015 0000 0015 0000 0015 0000 0015 0000 0015 0000 0040 0000 0015 0000 0015 0000 003F 0000 0040 0000 0040 0000 003F 0000 0040 0000 0015 0000 0040 0000 0040 0000 0015 0000 0611 0000 0055 0000 0E40

within the Arduino code

irsend.send(???, 0x????????, ??);

what did I miss please help me understand.

I am trying to find a list of infra-red codes that you use to send IR commands.
For example the following:

irsend.send(NEC, 0x1EE17887, 32);

Is there a list of all known brands and commands?

@Dheeraj maybe you can fix the example here for lazy eyes/asses like me. I just copied and paste and didn't notice the missing "s" Thank you so much for the quick support and the great plugin.

@Dheeraj is the light sensor supported? I am getting

20:32:05.069 [pimatic] warn: no plugin found for device "Light1" of class "MySensorLight"!

when starting pimatic with

{
      "id": "Light1",
      "name": "Lighti1",
      "class": "MySensorLight",
      "nodeid": 11,
      "sensorid": 0
    }

yet I am able to see the sensor in pimatic's logs

<- I_LOG_MESSAGE 0;0;3;0;9;read: 11-11-0 s=0,c=1,t=23,pt=2,l=2:39

I didn't search enough, http://forum.mysensors.org/topic/753/static-node-id-and-other-unanswered-questions

@Dheeraj, I have been looking all day for how to configure static node id , meanwhile I heard of mysensors last night so pardon me if I didn't find the doc that explain it. Can you point me in the right direction?
