Beginner totally lost during installation of serial gateway

[Julian Kröhl]

Hello guys,

I'm totally lost during the installation process and I really hope you can guide me the way.

Honestly, I read several installation guides and several tutorials but none of them seem to work - maybe I'm doing something very "common" stuff wrong, because I'm not a Linux guy.

I first followed the instructions to build 2 Arduinos with nRF radio chips.
One will be my gateway, one will be my "sensor" guy.

The gateway is attached via USB-cable directly to my Raspi, hosting Openhab2.
The communication between Sensor-Arduino and Gateway seem to work, at least I get stable output from the Arduino-Com-Console.

What I want to do now is to "introduce" my Gateway to openhab2 - and I'm completely lost now :(
I tried the guide "https://forum.mysensors.org/topic/1194/tutorial-openhab-with-serial-gateway", added the item to my sitemap and it states "-", so no data available.
I tried to check the logs of openhab2 but they seem to be not updated for one month (even after several restarts) - my other items I control with Openhab2 are working (Z-Wave-Stick controlled).

So the first step I fail at is
"Start up openHAB with "/opt/openhab/start.sh". You should see something like:
2015-04-02 20:05:30.731 [INFO ] [runtime.busevents ] - Arduino state updated to 0;0;3;0;14;Gateway startup complete."

What do I have to do exactly after I connected the Arduino gateway via USB?

BR,
kreisch

@julian-kröhl oh, you have found a really old thread. :smile:
I suggest you to go with the binding or with the MQTT gateway.

@timo
Thanks, I will go on with the mqtt bridge but to be honest, the Entry for a beginner is huge - and I am from it sector, so no complete noob, only regarding to Linux ;)

@julian-kröhl Firstly, are you familiar with OpenHab? If not, I'd suggest you pick a different controller, like Domoticz. OpenHab is much more advanced and more difficult to set-up for a beginner. Secondly, you have to do it step by step:

1. Setup a controller
2. Connect the GW to the controller and make sure the controller is recognising it. - this is the step you have to concentrate right now.
3. Only now start your sensor and make sure the sensor is talking to the GW.

Follow this one and aks questions back: https://forum.mysensors.org/topic/6694/openhab-2-2-mysensors-serial-gateway-how-to-install.

This is the one I have used and more or less it works. I have intermitent disconnections, but I am not fully sure if it is due to a bad radio link...

After following the full tutorial of the link above, I noticed I was not being able to connect. I would suggest you skip the part about downloading MySensors.git. This will install an alternative driver that I found not needed.

It is important to give OpenHab access permissions to the binding:

cd /usr/share/openhab2/addons/
sudo wget http://www.oberfoell.com/openhab2/org.openhab.binding.mysensors-2.2.0-SNAPSHOT.jar
sudo chown openhab:openhab org.openhab.binding.mysensors-2.2.0-SNAPSHOT.jar

And to the USB connection:

sudo usermod -a -G dialout openhab
sudo usermod -a -G tty openhab

In my configuration, I have a thing named "gw1" (this name you can change to whatever you like) defined for the gateway:

Bridge mysensors:bridge-ser:gw1 [ serialPort="/dev/ttyUSB0", sendDelay=200, startupCheckEnabled=false, networkSanCheckEnabled=false ] {
  // define things connected to that bridge here
 
}

As you can see, I am using directly ttyUSB0 to communicate to the serial gateway. You can check the right port by using the Arduino IDE in the Raspberry Pi and the serial monitor.

No need to have a 2nd arduino connected through usb. Just attach a nrf chip directly to your pi
