Hi there,
I'm trying to make a gateway on my pi and since the begining i'm stuck!
Using this: git clone https://github.com/mysensors/MySensors.git
i get: fatal: unable to access 'https://github.com/mysensors/MySensors.git/': Could not resolve host: github.com
I tried with sudo too! am i the only one getting this?
I see, i need to search for help on another forum ...
Many thanks to TimO who helped me a lot.
Wow ! this is what i was looking for ... Could anyone please share with us some Openhab settings for this wonderful Arduino sketch?
How can we assign in OH buttons to correspond to the physical buttons on the breadboard ?
Looking for any answer.
Thanks all!
Hey guys, i found the solution here array-relay-button-actuator but now the OH part comes 'couse this is different solution. How can i add CHILD_ ID's in this case to create more buttons in OH? i mean how to make difference between the two relays in OH?
Can somebody please help me? This is what i was looking for.
Thanks 
@TimO i solved following your tutorial here with dmesg and checking for what usb name rpi have for the gateway. Still not did those steps for a permanent usb but its on going.
Thanks!
Guys, i tried this sketch above and now it can be uploaded but its not working well.
The system reacts like this: the first button ( old one) turns the led on / off on the breadboard but its not refreshing the OH button on the webpage and i get some i get some WARN on the server like this:

I don't understand why i get so many things on the server pressing once on and once off!
The second button is completely dead, it doesn't do anything on the breadboard or on the web.
I think the Arduino sketch has some bugs somewhere even it can be compiled. Maybe something inside is wrong or maybe this is not the right way to multiply relays and buttons.
Please see bellow my OH settings.

Any suggestion will be kindly appreciated.
Thanks!
PS: I forgot to say that i added in the Arduino sketch the address of the node point:
#define NODE_ID 101
Thank you for sharing this code.
I modified your code only for a CT sensor which is connected to A0. The CT is connected to a 40 Watts lamp and this is what i get on Arduino serial monitor:
sensor started, id 4
send: 4-4-0-0 s=255,c=0,t=17,pt=0,l=5,st=ok:1.4.1
send: 4-4-0-0 s=255,c=3,t=6,pt=1,l=1,st=ok:0
send: 4-4-0-0 s=255,c=3,t=11,pt=0,l=18,st=ok:Energy Meter x 3v2
send: 4-4-0-0 s=255,c=3,t=12,pt=0,l=3,st=ok:1.2
send: 4-4-0-0 s=0,c=0,t=13,pt=0,l=0,st=ok:
send: 4-4-0-0 s=0,c=1,t=24,pt=7,l=5,st=ok:0.1
what is the last value (0.1)? Amps? if i turn off the lamp the i get 0.0!
In your sketch i see you calculate the real power, power factor, Vrms (volts?) and Irms (Amps?)
float apparentPower = emon1.apparentPower; //extract Apparent Power into variable
float powerFactor = emon1.powerFactor; //extract Power Factor into Variable
float supplyVoltage = emon1.Vrms; //extract Vrms into Variable
float Irms = emon1.Irms; //extract Irms into Variable
why is displaying in the serial monitor only one value which i assume is Irms?
I would like to calculate only the power and to export this to openhab but.....i dont know how 
@TheoL thanks man, I'll try it right now, thanks again.
@TimO still doesnt want to compile
this is the last error:
sketch_sep10b.ino:81:3: error: expected unqualified-id before 'if'
Error compiling.
Thanks!
Wow! thanks for your time to fill this sketch! appreciate that.
I tried your sketch and after cleaning some small mistakes i got these errors and i don't know how to lose them.
this is how the sketch looks:

sketch_sep09a.ino:85:1: error: expected declaration before '}' token

About the OH rules i made them like this:
rule "Light"
when
Item lightBar02 received command
then
if(receivedCommand == ON) {
sendCommand(Arduino, "101;1;1;0;2;1\n")
}
if(receivedCommand == OFF) {
sendCommand(Arduino, "101;1;1;0;2;0\n")
}
end
what do you think? do i still need to modify something?
Thank you a lot!
