Serial Gateway connection to Openhab

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.

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. :D

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!
