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 :scream:

@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.

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'

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:

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!:pray:

Hi! Can somebody please help here? I got stuck with my openhab server on my raspberry!
By now I was starting the server by:

Sudo /opt/openhab/start.sh

But I wanted more, to make it auto start on reboot so in case of power failure to auto start when the power is back. Therefore I followed some tutorials found on the www and I got it done, now the server starts alone but I cannot do anything from web page or from my phone. I also can't see the temp and humidity on the web or phone!
The question is how to stop this server? I tried different commands found on the internet but non of them can stop this invincible server I have lunched :)
I tried to stop it, remove, delete... Nothing works!
Is there any way to remove everything from my raspberry pi and to start it all over again with all the installation as for windows ? Format the partition, install the noobs again and so on?
Thanks.

Hi TimO,
I want to make a permanent USB setting for my Radberry and I follow your tutorial here.
In my etc/udev/rules.d I have two documents: 40-scratch.rules and 99-input.rules and I don't know where to make the needed modifications as you show in this tutorial.
The file you point to make the modifications has another name and I can't figure where to add the vendor, product and serial no for my arduino. Shall I make a new file called 99-usb-serial.rules and to write in it the ATTRS{idVendor} and the rest of them according to my dmesg as you say here above or to do that in one of the two files I have?
Thanks!

Hello? TimO? :) are you there?

Hi,
Can anyone help? I'm trying to move my server from my laptop to my raspberry pi 2 and I'm having problems.
I changed the port in the items file with

"String Arduino "Arduino" { serial="/dev/ttyUSB0@115200" }"

And now the server receive the commands from my laptop or from my phone but it not sends the info to the node point and it not receive info from the node point too.
If I start the server from my laptop with start.bat it works but when I start the server from my pi with
Sudo /opt/openhab/start.sh it acts as I said above!
Can anyone please help me understand what I'm missing?

Thanks!

Oh TimO i thought i'll never see you again here :) thanks for the answer.
I'm using the RelayWithButtonActuator example on which i added the humidity and temperature part and its working well. I choose this example because in this way i can get in real time the light status in Openhab even the light is turned ON / OFF from physical button on the breadboard or from the Openhab button.
The Openhab rules are already made with the V_LIGHT command not the V_TRIPPED.

I cant figure out what to add in the Arduino sketch to add more relays and more buttons and to make it work in the setup or loop functions. Than, on the Openhab rules i tried to copy the only light rule i have right now and to change some of the numbers in the

sendCommand(Arduino, "101;1;1;0;2;1\n") 

but its not working :(

If i'll get at least 5 buttons and 5 relays working in this way it would be perfect.

Looking for any answer.

@hek thanks for the answer. At least now i know i'm not alone :). Anyhow as far as i've seen by now only @TimO was the only one who answered me and gave me some info. It is possible that non of the heros, admins or other kind of this forum members to have a suggestion for me?
Sorry if i was aggressive again!

Good help :)

People i see that this post was seen by more than 2k times but nobody is answering! How is this possible? Nobody knows how to do it or everybody enjoy watching a noob asking for help? Common people at least off topic let's say hi each other!

@maglo18 I saw some words in your pictures that looks familiar like faza or analizator :)
Can you share your latest Arduino sketch or if you have a complete tutorial about this project would be helpful.
Thanks!

@gigaguy i was asking for help building a new and simple system using one ct sensor to get 3 values in openhab: instant power in watts, energy consumption up to date in kWh and the total energy consumption starting with the app upload in kWh. I don't want to see volts or amps!
The problem is that I don't know how to combine the emoncms example with mysensors and than to create rules in openhab!
As you have already a energy monitoring in your house you just need to find a way to combine all together in one app like openhab.

Here nobody too? Please help!
