How so?
I've tried running the command you've supplied, but it doesn't work... Do I have to install mosquitto?
I didn't see it anywhere in the guide.
Everything is working at the moment, you think it can pose a problem later?

@Tigroenot
That fixed it indeed XD
Thanks for helping me out

I got the previous problem out of the way for now...
Now onto the next one.

I started a node and now I can clearly see data being sent and received on my serial log and ssh. (See picture)

So I tried adding the gateway to domoticz using following settings:

Yet if I check hardware setup I can see no nodes being presented.

Are there settings or steps I missed?
Greetings

Hello
The past two days I've been trying to setup the gateway on my RPi 2 with domoticz.
Here's what I did.
I installed domoticz onto my raspi, then I tried the install the gateway.

git clone https://github.com/mysensors/MySensors.git
cd MySensors

Afterwards I did the following

./configure --my-gateway=mqtt --my-controller-ip-address=127.0.0.1 --my-mqtt-publish-topic-prefix=mysensors-out --my-mqtt-subscribe-topic-prefix=mysensors-in --my-mqtt-client-id=mygateway1

make

sudo ./bin/mysgw -d

Then it seems to start normally onto the point where it refuses to connect to anything.
Does anyone have a clue what's going wrong?
I can't seem to figure it out. I've tried it several times over, and always go similar results.
I was using GertSanders's connector for the RPi Hub and I've tried it with normal wiring too.
As far as I can see it shouldn't be a wiring problem...

EDIT:
!UPDATE!
I think I just fixed it. I reconfigured it to include the IRQ Pin and now it's just listening for throughput

pi@raspberrypi:~/MySensors $  sudo ./bin/mysgw -d
mysgw: Starting gateway...

@GertSanders
Then I'll temporaraly switch over to a serial gateway.
Thanks again for the info!

@GertSanders
So I just succesfully updated the code to library 2.0.0
Yet, now nothing shows up in domoticz. Do I also need to update something to the raspberry pi 2 (which is acting as the gateway).
Since the serial gateway is stating to be succesfully sending information.

@GertSanders
Oh right! Guessed I missed that while copying and pasting everything.
I just remarked there was a v2.0 while writing the sketch... Might rewrite it while I'm busy

@GertSanders
Okay
So after editing your code to work on the slightly older mysensors library I still have installed, all seems to work!
Thanks a lot for your help!

@GertSanders Thank you!

So, you are basically sending a light intensity value between 0 and 100 to domoticz.
I'm going to leave the battery part out because my sensor is installed near a power outlet, and I can just use power from an adapter.
I'm testing it now, and reporting back with my results!

Hello

Since I'm a student and the holidays have begun, I finally have time to convert my purchases online into a domotic system.
I succesfully set up my raspi 2 with domoticz and started working on my very first sensor.
Now in the "build section" at light, there are true light sensors used, but I only needed an estimated value on which I can base actions.
So my idea was to use an LDR and some calculations to convert the analog input to a luxish value.
Now... I've edited the "light" sketch from the build section to send the value I calculated, but when I look in domoticz, at "Hardware setup", it seems like this child is sending no values. (screenshot below).
And when I go to "setup devices", this sensor doesn't even show up. (screenshot below)

Can anyone check my code and say what I've done wrong. I'll also add a picture of my breadboard in a moment. Don't know whether that'll be clear though.
