openHAB binding

Pavel Hrudka

Hi.
I just added your binding and I am very happy for it because I have spent quite some time to figure out, how do I integrate mySensors in to Openhab.

My setup
RPI2
did apt-get update && apt-get upgrade
OpenHab (openHAB runtime has been started (v1.8.1))
I have NRF24L01+ connected directly to RPI using SPI.
I am running PiGatewaySerial service and Iam able to see communication when i do

sudo cat /dev/ttyMySensorsGateway

for example

7;255;3;0;15;0
7;255;0;0;17;1.5.4
7;255;3;0;6;0
7;255;3;0;11;Humidity
7;255;3;0;12;1.0
7;0;0;0;7;
7;1;0;0;6;

My problem is that openHab is unable to access /dev/ttyMySensorsGateway
I see error in my logs

2016-03-11 23:30:11.288 [ERROR] [.o.b.m.internal.gateway.Serial] - Unable to find Serial port '/dev/ttyMySensorsGateway'

I found @BastienVH post and modified /etc/init.d/openhab JAVA_ARGS_DEFAULT section and added at the end of defintion

 -Dgnu.io.rxtx.SerialPorts=/dev/ttyMySensorsGateway"

and restarted service

Sadly, there was no change.
Please can you help?

Thank you.

I use RP2 with internal serial connected directly to ATmega328 chip. So it is also a unconventional serial. And for that to work I had to put the line " -Dgnu.io.rxtx.SerialPorts=/dev/ttyMySensorsGateway" on my start.sh file, before the line that has ".jar"

Hope it helps

@Pavel-Hrudka

On my last post I miss lid you, copping your own line, but actually to use raspberry internal serial you have to add to Openhab's start.sh "-Dgnu.io.rxtx.SerialPorts=/dev/ttyAMA0 " before the line with the ".jar" because the serial got to start before you run the biddings.

Hope it helps.

Pavel Hrudka

Hi thank you.
I solved my issue, but when I wanted to update my post, the thread was locked.

Here in this post its said that I should create link to virtual port like this

sudo ln -s /dev/ttyMySensorsGateway /dev/ttyUSB20

Pointing OpenHab binding to this port solved my problem.

I did try to add command line parameter to /init.d script for OpenHab but that did not work.

Cheers.

Hi I am new to openHAB how do you configure a relay node? I do see the node in the logs but the relay don't what to switch on or off. I have my temp and humidity sensors working already.

18:38:50.450 [INFO ] [.b.m.internal.MySensorsBinding:257  ] - New MySensor sensor found (Dimmable device of some kind): node-id=95, sensor-id=0 with type S_DIMMER

Hi,

Quick question, trying to integrate the mysprinkler project into openhab.

getting stuck using V_VAR1-3 i need to somehow export out a runtime variable to the remote ardunio... any idea how i can get the V_VAR1-3 to output something that is not binary? i.e a runtime of 5 min for sprinklers...

i have the triggering working, just can't configure the runtime.

any help appreciated.. will do a guide if it get it working :)

I recently moved my OpenHab install from a Raspberry PI 2 to a Raspberry Pi 3 from wheezy to jessie and now the biding is not working. Everything was working perfectly with the previous install now i keep getting the following message, serial port exist and it works. I suspect it has do to with the change from wheezy to jessie but nothing i tries is working.

From https://github.com/openhab/openhab/wiki/Serial-Binding

If you are using non standard serial ports you have to adapt start.sh to have the serial port included. the java command line should then include the following parameters:

-Dgnu.io.rxtx.SerialPorts=/dev/ttyAMA0

whereas ttyAMA0 is the path to your serial port. Please be aware to change all scripts you might use for startup (debug, automatic start in linux,...)

@ted said:

-Dgnu.io.rxtx.SerialPorts=/dev/ttyAMA0

I tried that but it did not work - this is how part of the /etc/init.d/openhab looks - any other ideas - i did not needed this with the RPi2 and wheezy

@Harry-Gomez
What if you modify start.sh and start openhab from console? I'm not a linux expert; could it be that the usb driver was initiated after /etc/init.d is processed ?

Harry Gomez

@ted

Thank worked with change to openhab.sh - I had to put -Dgnu.io.rxtx.SerialPorts=/dev/ttyUSB0 at the begining to be able to work. I'm not sure why it would workthere and not on the /etc/init.d/openhab. Also there is not start.sh when you install using apt-get it is named opendhab.sh

Thanks!!

Hi what is the syntax for a relay in openhab using this binding?

This in what I get in the log but the light do not switch on or off.

2016-03-27 20:37:00.068 [INFO ] [runtime.busevents             ] - LightSwitch_GF_Study received command ON

This is the syntax that I am use and it is not working. Also try V_LIGHT without any luck.

Switch LightSwitch_GF_Study	"Study Light  [%s]"				<light> 	(GF_Study)			{mysensors="41;1;V_BINARY"}

andredts

@Francois

Hi, I use {mysensors="12;0;V_STATUS"}. Remember to give your node a ID, because OH does not give one.

bkl

Hi @Francois

The syntax look OK.

This is what i have working.

Switch  Relay_10_0              "Relay 1"                       <none>                                  {mysensors="10;0;V_STATUS"}

Try and turn on debug log for mysensors

Add this to logback.xml

<logger name="org.openhab.binding.mysensors" level="DEBUG" />

Francois

Hi @bkl

Are you using the standard relay sketch with this binding or did you change anything in the sketch as I just don't get my relay to work.

Here is my log with the above string in my logback.xml.

Note2: If you are using non standard serial ports you have to adapt start.sh to have the serial port included. the java command line should then include the following parameters:

-Dgnu.io.rxtx.SerialPorts=/dev/ttyAMA0
whereas ttyAMA0 is the path to your serial port. Please be aware to change all scripts you might use for startup (debug, automatic start in linux,...)

So my question (linux newbie) is what is the best way to attach my Arduino nano to rpi, so that it always find it on reboot or if it is unplugged/replugged.

Is this correct and will this work with the binding?
/etc/udev/rules.d/99-usb-serial.rules"

Hi
I use RASPBIAN JESSIE.
Command minicom -b 115200 -o -D /dev/ttyUSB0 show traffic from serial gateway.
I write -Dgnu.io.rxtx.SerialPorts=/dev/ttyUSB0 to /usr/share/openhab/bin/openhab.sh and /etc/init.d/openhab but still 'Unable to find Serial port '/dev/ttyUSB0''.
Please help me

@Harry-Gomez
That's all well done. does not work. It may be necessary to install any more bindings or the Java packages?

Harry Gomez

@zeblong

Do you have the serial package installed --> org.openhab.io.transport.serial-1.8.2.jar?

Did you add openhab to dialout group -> sudo usermod -a -G dialout openhab

What is the error on you logs?
