Serial Gateway connection to 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. :-D

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,

cant test this version because i get this error regarding DHT:

i have downloaded all needed libraries from here http://www.mysensors.org/download/ but cant compile!
do i need ther DHT library?
thanks!

@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 .... :(((

TimO

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.

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?

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.

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.

@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....
