Serial Gateway connection to Openhab

[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.

@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....

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.

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:

On the serial monitor of the node point i receive this:

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!

[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!
