Hi, I´m using the MultiRelayButton 0.9b sketch, that I found here in the forum:

If you like I can try RelayWithButtonActuator Example, but I like the other better because it works when the server is down, no aka from server to make the state change.

@andredts
It was a bug in the code. If you download the new jar then it should be fixed.

@bkl
Thanks, I will give it a try and return to you with feedback.

@bkl
Working beautifully. I have three relay and three switches on the arduino, and no matter how fast I press them I got no miss command. Thanks

I got one bug, but I think it is Openhab's, when I changed the item file with Openhab running and the switch in the user interface got inverted ON-OFF and OFF-ON.

Hi,

Today I was testing Motion and Door sensors. Motion worked as expected, but the door sensor only works if it's set in OH as a "switch" item(on and off feedback), if you set it as a "contact"(open/closed) item you get the log: " No item configured for "5;1;V_TRIPPED". I have used the example sketch for the sensor

@andredts I also notice this with the door sensors. Normal the item must be contact and not switch.

@andredts
Thanks for the feedback, this is now fixed.

@bkl
Thank you for your great work. Happy to help with what I can.

Already tested and fully abandoned rules for setting up OpenHab with Mysensors.

Next I will try a analogic read, based on the dust sensor.

@andredts
Using this bidding for 15 days, with 3 relay, a Micro Sensebender, Humidity, Motion and Water level (base on dust sensor). And everything is working great.

Thanks again.

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

andredts

@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!!
