Serial Gateway connection to Openhab

jemish

At this link: http://www.mysensors.org/build/serial_gateway I got the arduino sketch,
but I want to know, this sketch is for main arduino that is connected to the raspberry pi via serial communication and other side it is connected to the nRF24L01.

If it is true than, I want to know which code is required at node side where I can ON or OFF LED and LIGHTS or DIMMER.

jemish

Hey.....please can anyone reply me?......please......

@jemish This is to basic to earn an answer. I suggest you start reading at http://www.mysensors.org .

hi,
I have a question, that how can I get feedback from our switchboard that is at our wall.

If I am on the light by pressing the switch at switchboard.

If in case I get the 5v from switchboard and give it to the Arduino, than how can I update state of switch in openhab.

jemish

Hay, can any one try that.........feedback from switchboard

TimO

I would try to use something like this on the sensor connected to the switchboard:

http://www.mysensors.org/build/binary

This will send V_TRIPPED per default.

In the rules files you have to bring everything togehter:

if V_TRIPPED from sensor_id_xyz received
then update status of light switch

If you know what I mean.

Hi all,
I wrote some rules for serial gateway to openhab, temp, hum, switch, dimmer and some internal commands are working without a problem. I don't have too much time to develop this for other devices.
I'm not a java programmer so if I made some mistakes feel free to comment.
The goal is to write a rules that will be easily expanded to other devices.
I create a has map table where I define mappings ID to item name and inversely.

hi all,

does anyone have an arduino code for l154 nice work here above?
i need an example only for arduino (dont have a rpi) on which i can connect a few relays and a few sensors like dht11 and a light sensor.
Someone please a little help here with a arduino code or some links on where we can find something to work with this openhab configuration?
thanks in advance.

ewgor

one more question:
to make the connection with openhab should i change this "String Arduino "Arduino" { serial="/dev/ttyUSB0@115200" }" to "String Arduino "Arduino" { serial="COM4" }" couse my arduino is connecting on com4?
thanks!

Use something like:

String Arduino "Arduino" { serial="COM4@115200" }

thank you for answer TimO, i assume this 115200 is the baud rate, isn't it? on testing different arduino codes, i had to modify it to 9600 because otherwise it wouldn't work...
can you please share with us any arduino code for a few relays and some sensors? or to suggest us some links where we can find something useful?
i need an example only for an arduino (mega) connected directly through usb to my laptop.
thanks again, i will try this "String Arduino "Arduino" { serial="COM4@115200" }" when i'll have an arduino code as an example.

TimO

Yes, you're right, 115000 is the baudrate.

Have you seen my tutorial?

http://forum.mysensors.org/topic/1194/tutorial-openhab-with-serial-gateway
tutorial-openhab-with-serial-gateway

ewgor

I saw your tutorial but in there you speak about tests made on a system with Linux like a rpi and I'm working only for tests from my laptop with windows 7 and arduino mega! Later when I will have something working I'll purchase a rpi for a permanent installation but for the moment I need just the arduino code to match with this openhab configuration.
Any idea?
Thanks again.

TimO

I'm using the standard serial gateway: http://www.mysensors.org/build/serial_gateway
(For the mega you have to change CE/CSN Pin, just search the forum)

The OpenHAB part of my tutorial will work on Windows 7 too, there's no difference in the OpenHAB configuration except the COM4 port you already mentioned.

The arduino code you're searching is the MySensors standard stuff, there is no need to change that to make it work with OpenHAB.

ewgor

@TimO i am trying to make this serial communication work following your tutorial. i don understand why it has to be so difficult for some of us who have small ideas about arduino i mean is not like today a bought it and i don't know a thing about it!
cause was not working with my existing openhab i deleted all and i followed your link here https://openhab.ci.cloudbees.com/job/openHAB/ and i got this"distribution-1.7.0-SNAPSHOT-addons.zip" and this "distribution-1.7.0-SNAPSHOT-runtime.zip".
now, do i need all addons or a few of them? if i need a few, which one? its not clear ...
regarding arduino, i got all libraries from here http://www.mysensors.org/download/ and extrated into the libraries folder of arduino.
when i compile the example sketch SerialGateway, it is compiling and i even can upload it but, starting the server with start.bat or start.sh and having the com4 modified and all items, rules and map according to your instruction, it doesnt work, i get this error "Error opening serial port 'COM4'.
i dont know what to do! and i don't understand how to see the temp and humid. real values when you have uploaded a standard serial gateway and you don't have any commands in the arduino code about dht or other type of sensor! is this code only for test? just to see that you have the communication working and on the web it will appear just some values?
its becoming really frustrating trying days and nights to make it work,, reading a lot of comments where other guys made it and you don't!
can u please help? where i'm wrong? i'm using this time an arduino uno but this doesn't matter, i changet the string with baudrate115200, 9600, without it and nothing! i cant make the serial communication work!

@TimO hi here too,

do i need ther DHT library?

@ewgor Hi!

Using OpenHAB (1.X) with MySensors is a long and at the beginning frustrating process as OpenHAB itself don't support MySensors out of the box. I hope I'm able to change that with OpenHAB 2.0.

OpenHAB 1.7.0 is stable. You don't have to use the snapshot release. But that won't solve your problems.
You just need the serial binding from the addons. Copy "org.openhab.binding.serial-1.7.0-SNAPSHOT.jar" to "OPENHAB-HOME/addons". But I suppose you already did that, because of the error "Error opening serial port 'COM4'.
https://github.com/openhab/openhab/wiki/Serial-Binding according to this "COM4@115200" should work fine. I've not tested it with windows yes. This is your main problem. Don't try to go further, nothing will work. Are you able to open the serial monitor in the Arduino Development Environment? With the correct baudrate you should see something like "Gateway startup complete".
You're Arduino Development Environment can't find the libraries. I've extracted all libraries to "C:\Users\myUser\Documents\Arduino\libraries". It now looks like:


Adafruit_BMP085
BH1750
Bounce2
...
DHT
...
MySensors
...

The DHT library is part of the file you downloaded.

ewgor

@TimO thanks for reply,

first shot was with Openhab 1.7.0 from here http://www.openhab.org/downloads.html and than i followed your link from here https://openhab.ci.cloudbees.com/job/openHAB/ and tried with the SNAPSHOT 1.8.0 version, both of them works and i can test different examples from here with my laptop and 2 smartphones.
every time i try a server, i have 2 folders with as follows: 1 folder is the original addons folder wich is empty and another one as a copy like addons1 in which i extracted all addons. Before starting the server i copy the needed addon (.jar file) in the original folder named addons, in my case the serial.jar.
if the server is not started i can compile the SerialGateway code and i can upload it too into my arduino. The problem si that when i open the serial monitor of arduino IDE i get some strange chars like: \Ú or LÊ or Lœ and this is happening every time i open the serial monitor. I think is a baudrate problem but i cant see where in the SerialGateway sketch i can change this baudrate or should i change it directly in the library? By the way, can you please tell me, why its not working with different baudrates?
i have all libraries from here http://www.mysensors.org/download/ copied and pasted directly in my arduino libraries folder which in my case is in D/kit/arduino/libraries. For DHT i have DHT library / DHT tester! Do i need other library? i Know i tested a sketch for DHT11 and an LCD and it worked.

However, if i have the server started on my laptop its impossible to compile the SerialGateway sketch and i receive this error posted above. I even can't upload the sketch if i close the server, i need to restart my PC....

Maybe it would be a beeter sollution to use Mqtt because i have a wiznet w5100 and a ENC28J60 ethernet module but the problem is (i asked somewhere here on the forum) that i cannot use or test Mosquitto broker, and so i cannot test a Mqtt connection. I downloaded the broker from the original page for my system, i have it installed on windows but i cannot access any of the .exe files because of some missing dll. After days of searching and a lot of struggling i got the dll's but didn't start because of some unexpected error! I know this is the subject of another topic but i didn't get a reply there so i ask here...
If i cannot test a server on my machine how to purchase a RPI and moreover i never had a RPI so you can imagine how many problems i will face. Anyhow, this is my intention, to buy a RPI and to have a permanent installation.
Don't know what to do .... :(((

Ok, I think we're getting closer.
So, If you see strange chars in the serial monitor the baud rate of the serial monitor isn't right. Just change the baud rate in the serial monitor, it's a dropdown at the bottom right. If you set it to 115200 baud it should work (Gateway startup complete).

The 115.200 is a fixed baud rate MySensors uses. It is faster than 9600 and the serial communication could be the bottleneck. In the MySensors library it is defined in MySensors.h. You may change that, but that won't help.

I suppose you have a blocking issue, since both Arduino IDE and OpenHAB try to use the COM port. Try to make sure only one application at a time is running and using the port. At least OpenHAB should throw an error that the COM port is blocked. I'm not sure how Windows handles blocking.

If you see "Gateway startup complete" in the Arduino IDE / serial monitor, close the Arduino IDE (and the serial monitor) and fire up OpenHAB with debugging enabled (start_debug.bat). Post everything the serial binding throws out here.

Can't help you with MQTT because I haven't used it yet.

ewgor

I changed the baud rate to 115200 and now it says "0;0;3;0;9;check wires" on both Arduino (Uno and Mega). I think i saw a topic here somewhere, do i need to change some pins in the SerialGateway sketch?

TimO

Check the connections between NRF24L01+ and Arduino Uno.

In case of the Arduino Mega you have to change the sketch (CE/CSN Pin), just search the forum for an example.

ewgor

I dont have any NRF24L01 in myhouse! what is this device? do i have to buy one to see this SerialGateway working between my PC and my Arduino board?
For my Mega ive searched on the the forum but i dont understand how to change the CE/CSN pin ...
I asked on some other topic but no answer.

tbowmo

@ewgor

Have you read this page ?

and this one.

NRF24L01 is the essentially the heart of the mysensors system, it's the radio which it's build uppon.

ewgor

@tbowmo yes i did, only is just i didnt understand that the NRF24L01 is a must! I already ordered a piece and in a few days i'll be able to test either the Serial Gateway or the Ethernet Gateway....

ewgor

This post is deleted!

i solved the problem with DHT, now i need to know how to configure Openhab in order to see the the gateway. I changed the COM in items already.
In order to test your sketch that one with DHT and 2 realys what should i do? do i need 2 arduinos: one as a gateway and 2nd as a node point? how many nRF modules do i need?
Now i have nRF24L01 but i dont know how to make it work with OpenHAB
In addons i have org.openhab.binding.serial-1.7.0.jar
Any help please?
Thanks.

ewgor

Anyone, any idea how to test the serial gateway? At this point on the serial monitor i get 0;0;3;0;14;Gateway startup complete. How to test it with Openhab? PLS HELP
For gateway im using a UNO and i try to have my mega as a node point. If i use Arduino Mega as a gateway its ok, i couldnt find any connection scheme for the node point (mega or uno). Right now i see on the serial monitor of the node point check wires and on the gateway startup complete! Where is the problem? how to connect the node point with my relays and what should i see on the serial monitor? Again somebody pls help me understand how to test it with Openhab?

TimO

For the Arduino Mega you have to change the connections. Check out this thread:

http://forum.mysensors.org/topic/249/arduino-mega-sensor-shield-2

When the "node point" starts up fine you should see a lot of messages coming on the serial monitor of the gateway. Then the communication between both nodes is working.

ewgor

@TimO with your help again i managed to find the right pins on my mega and now with my dht11 connected i get the temp and hum values constantly. On the server side when i start the bat file or sh file i get the values on the node serial monitor but nothing apears on the localhost.
there are any changes that needs to be done in the items, rules or the sitemap?
thanks for replay.

ewgor

today, trying to make it work i discovered that if i start the Openhab server i get the DHT11 values on the server and i can access the serial monitor of the node point but when i switch the arduino IDE to the serial gateway com4 i get this errors on the arduino IDE and i cannot acces the serial monitor:

help

TimO

The access to the serial port is exclusive, stop OpenHAB to access the serial port of The gateway with the arduino IDE.

ewgor

@TimO i saw that I can access the gateway and see what node point transmit but as you say without having the server start.
How do I see temp and hum on the local host? And what do I need to do to switch the two LEDs from local host?
As always, thanks for sharing a little part of your experience

TimO

Use something like this in the rules file:

For a button (always sends on when activated):

rule "Licht Flur EG"
        when
                Item corridorLight01 received update
        then
                sendCommand(Arduino, "102;1;1;0;2;1\n")

For a switch use something like

rule "Küche"
        when
                Item kitchenLight01 received command
        then
                if(receivedCommand==ON) {
                        sendCommand(Arduino, "102;1;1;0;2;1\n")
                }
                if(receivedCommand==OFF) {
                        sendCommand(Arduino, "102;1;1;0;2;0\n")
                }

end

ewgor

So TimO you say your example above (arduinos sketches for the serial gateway and the 2nd one for temp, hum and two switches + openhab items, rules and sitemap) is not working? i just followed and nothing happen ... still strugling. Now you give me this example which has nothing to do with your example. If i want to use it i need to modify all files and i dont know how!
Can anyone help me??

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.

ewgor

@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

ewgor

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.

ewgor

@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!

Fay Candiliari

@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:

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.

aaron832

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)

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

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.
