Serial Gateway connection to Openhab

[TimO]

Well, I thought your base is my tutorial: http://forum.mysensors.org/topic/1194/tutorial-openhab-with-serial-gateway

The advantage of OpenHAB is, you're very free and are able to do things you like to do. The disadvantage is, you currently have to "program" your rules.

It would help to know your OpenHAB configurations, sketches and so on, because I'm using my own OpenHAB (and MySensors) configuration/installation, that certainly is not the best configuration für everyone.
(But it works the way I want it to work ;-))

You only asked for (and got) pieces of the puzzle, you have to put it together by yourself or ask for the complete solution, as you did in another thread. :D

@TimO
I see, so if are not a programmer and you don't know how to make your own sketches (arduino, rules) you don't have any chance to make your own project .... i thought, being open source and asking for help in a community where you can find a lot of guys who have idea about the subject, maybe you can make it easier without spending hours and hours just to come back to the same place you started , moreover without a solution.
Anyhow, thanks a lot, with the help you gave i am almost there but i think i still need to wait maybe a half year till i'll see my project on :(

Hi,
Can anyone help? I'm trying to move my server from my laptop to my raspberry pi 2 and I'm having problems.
I changed the port in the items file with

"String Arduino "Arduino" { serial="/dev/ttyUSB0@115200" }"

And now the server receive the commands from my laptop or from my phone but it not sends the info to the node point and it not receive info from the node point too.
If I start the server from my laptop with start.bat it works but when I start the server from my pi with
Sudo /opt/openhab/start.sh it acts as I said above!
Can anyone please help me understand what I'm missing?

Thanks!

[TimO]

Try to connect with a terminal software like miniterm to /dev/ttyUSB0 and check if data from the serial gateway is received.

miniterm.py -b 115200 -p /dev/ttyUSB0

You may have to install miniterm first.

@TimO i solved following your tutorial here with dmesg and checking for what usb name rpi have for the gateway. Still not did those steps for a permanent usb but its on going.
Thanks!

@TimO Hi TimO! This is Fay from codebender.cc Thank you for using codebender! I just wanted to let you know that one of the sketches you are using in this comment has been deleted and so it is not available for users to view it. Let me know if you have any question. :)

[TimO]

@Fay-Candiliari : Thank you very much for the hint!

Hi @hek Likewise! :)

I'm having trouble with test.rules when two switches change its values really quickly one after the other. I can do that in a couple of tries via the web UI or the android UI. This is the output that looks odd:

2016-01-05 19:39:54.405 [INFO ] [runtime.busevents             ] - relay01 received command ON

Light Item: relay02 Light: ON
Light Item: relay02 Light: ON

As you can see, it starts fine but at the end it is talking about the same relay twice and I end up with just one relay on. It actually looks like an openhab issue but I'm not sure.

Any help is appreciated.

I am having the same issue. When I start my sensor, it sends a lot of information seemingly at once. The rule gets confused and runs the rule multiple times on one serial command (rather than each individually).

Notice below the "Arduino" item is getting updates frequently. Below that is my output in the rule to handle the update. Notice it prints multiple 105;0;0;0;7; in place of the other inputs (105;255;3;0;15; for example)

@knoid
Found out that you can use locks in the rules to prevent uncertainty with the "Arduino" variable caused from multiple instances of the rule running simultaneously.
Example:

import java.util.concurrent.locks.ReentrantLock

var java.util.concurrent.locks.ReentrantLock lock  = new java.util.concurrent.locks.ReentrantLock()

    rule "Arduino sends to Openhab"
    when
        Item Arduino received update
    then
        lock.lock()
        try {
            // do stuff (e.g. create and start a timer ...)
        } finally{
           lock.unlock()
        }
    end

Cool! Thanks for sharing!

I know... it's an old thread. And i know openHAB2 is there. But it's still Alpha and i am beginner. Maybe not a good idea ;)

Somehow my sensors will not bind. I downloaded and installed all fresh.
When i start openHAB with sudo it loads normal but nodes never connected to openHAB :(

EDIT:
I just made a new install combined the infos from these instructions and that worked for me:
https://github.com/openhab/openhab/wiki/Linux-and-OS-X#apt-get

Thx for your answer Tim0 and sorry for posting in wrong thread

[TimO]

Hey @edsteve !

This thread mainly covers the serial connection via the serial binding and by using rules.

You are using the binding for OH1, so I suggest to start a new thread or trigger @bkl. :-)
