I found the problem ...
due to a defective sensor (light meter) the arduino could not initialize correctly.
I think that is why it was calling back setup()

thank you for the link

18743 MCO:PIM:NODE REG=1	Registration response received, registration status 1
18746 MCO:BGN:STP	Callback setup()

What is Registration status 1?
Does Callback setup() reinitialize the node?

Arduino Mega Node not working anymore
I have an arduino mega used for automated irrigation after a year of service the node is not responding anymore.
The node runs on mysensor 2.1.1

I alread updated to MySensors 2.0

This is the update code:

I managed to find an addons directory in /usr/share/openhab2/addons, but I can´t find a way to copy the .jar file there, as I get permission denied both through WinSCP in sudo mode and terminal ssh. The folder has permission 0775.

That is the correct directory if you installed OH2 via .deb. Seems like you are using a user in WinSCP that is not allowed to write to the directory above. To circumvent this:

1. Copy the binding jar to /tmp.
2. Login via ssh and execute:

sudo cp /tmp/org.openhab.binding.mysensors-2.0.0-SNAPSHOT.jar /usr/share/openhab2/addons/

and

sudo chmod openhab.openhab /usr/share/openhab2/addons/org.openhab.binding.mysensors-2.0.0-SNAPSHOT.jar

OH2 is started/stopped/restarted with

service openhab2 start/stop/restart

To log into the karaf console do:

ssh openhab@localhost -p 8101

Password is: habopen

Follow the guide/wiki from:

In the console enter feature:install openhab-transport-serial

I have installed openhab with the openhabian image. I could start the mysensors gateway too.
I followed the github-openhab2 installation instructions.
To this point

In the console enter feature:install openhab-transport-serial

I read a lot of posts on this thread but on get this error:

openhab> install openhab-transport-serial
Bundle IDs:
Error executing command: Error installing bundles:
	Unable to install bundle openhab-transport-serial

the chmod line posted above doesn't work neither. chmod does not accept openhab.openhab

I dont have any clue how to install the binding for openhab2 ... why isn't that possible from paperui

sudo apt-get install g++

then I could do "make"

ok thanks
i'll try

Make command doesn't work on openhabian image.

I installed openhab with the openhabian image and it works.
I did the following ...

What's wrong?

@m1rk0
In Line 95 is the following expression:
if (Irms < 0.3) Irms = 0;

Irms is RMS current. The expression sets all current smaller than 0.3 as 0.
You can delete this line for smaller values.
I suggest to use a SCT-013-005 instead of a SCT-013-030.

I optimized my code with the help of Surge.
I added a KWH reading on a restart of the node.
Now it's Version 1.3
