Serial Gateway connection to Openhab

[Matt Perry]

Thank you for this great information. I have been setting up Openhab for the past month, and I've been trying different types of nodes using Moteino (Arduino clone) and RFM69 radios. I have also started building some scripts for Openhab to help streamline the receipt of serial messages. All of this is due to the great information I have found here and in other places on the forums.

The one issue that has me frustrated is when I reboot OpenHab (I am currently using a headless raspberry pi). In order to get the sensors to work I have to unplug and re-plug in my gateway, and then run around the house and cycle power off and on to all my other nodes. Sometimes this works, and sometimes this doesn't work. Is there a reliable way to restart the serial gateway via software?

I just did some more troubleshooting and noticed that when I fully reboot the entire raspberry pi, that it comes up correctly. However, sometimes I just want to exit and reboot openhab while I'm doing development.

Once I find out how to make this part more reliable, the whole system will be working great! Thank you again for all of your very knowledgeable advice!

@Matt-Perry
I don't need to restart the serial gateway when I restart OpenHab.

Do you use a static or auto node ids? I'm using static node ids. Maybe that is the reason you have to restart everything?

When restarting OpenHab it outputs something like: "Removing stale Lockfile on "/dev/ttyACM0 .." and that's it.

[Matt Perry]

@TimO

I am giving the nodes static IDs. Here is an example of how I initialize an IR receiver/transmitter that I'm testing...

#include <MySensor.h>
#include <SPI.h>
#include <IRLib.h>

int RECV_PIN = 8;

#define CHILD_1  3  // childId
#define NODE_ID 101

IRsend irsend;
IRrecv irrecv(RECV_PIN);
IRdecode decoder;
//decode_results results;
unsigned int Buffer[RAWBUF];
MySensor gw;
MyMessage msg(CHILD_1, V_VAR1);
 
void setup()  
{   
  irrecv.enableIRIn(); // Start the ir receiver
  decoder.UseExtnBuf(Buffer);
  //gw.begin(incomingMessage);
  gw.begin(incomingMessage, NODE_ID, true);
  // Send the sketch version information to the gateway and Controller
  gw.sendSketchInfo("IR Sensor", "1.0");
 
 // Register a sensors to gw. Use binary light for test purposes.
 gw.present(CHILD_1, S_LIGHT);
}

Again, if I fully reboot my raspberry pi, it works (I am running Openhab as a startup script). But, if I want to troubleshoot a little bit, and "kill" the Openhab process and then call "start.sh" on the command line, the serial gateway does't reinitialize. Maybe I'm missing a step somewhere?

If this problem only relates to me, I don't want to waste too much forum space. I could very possibly have something set up wrong on my end and I'll figure it out!

Thanks!

[TimO]

What did the OpenHab debug messages say?

Did you check the permissions? Which user starts OpenHab with the startup script and which user do you use when you call "start.sh". Maybe there is a block because of the lock file? Kill the lock file (something like: "/var/lock/LCK..ttyUSB0") after killing OpenHab and before restarting with "start.sh".

I'm currently not using a startup script, I'm using "start.sh" within a screen session, which I'm able to resume for debugging or to kill OpenHab.

My network of MySensors nodes keeps working and reporting (temperature for example) and as soon as there is a controller running, the information is received.

[Matt Perry]

@TimO

Thanks again for the reply. Everything is working now. I believe the issue was with the serial connection moving to ttyUSB1. I'm not sure of why, or how, but I did create a SYMLINK and everything works just fine now, no matter what USB port the device is plugged into.

Thanks again!

[Jan Gatzke]

@TimO I tested your openHAB configuration and it is working fine most of the time. There is still one problem I was not able to fix. Some payloads have a dynamic length. Your example rules base on fixed length of the transmitted values, right?
I tried to split the incoming strings with string.split("\n"), but the \n seems to be removed by openHAB or the serial gateway. Any ide how we can resolve this? Without this issue openHAB would work perfectly together with the serial gateway.

Hi

I have the same problem with Matt and tried USB01 but didn't work.
When i unplug the usb, server error : Write action failed! Input/output error2015-03-03 19:25:23.682 [ERROR] [b.serial.internal.SerialDevice] - Error writing '100;3;1;0;0;1
' to serial port /dev/ttyUSB0: Input/output error in writeArray

Only solution for me stop server, unplug serial usb and plug it. I think ---Kill the lock file (something like: "/var/lock/LCK..ttyUSB0")--- will give the same solution like unplug the usb?

[C.r.a.z.y.]

When i unplug and plug again the serial USB from raspberry :

How can fix this?

[Jan Gatzke]

Why are you using a usb to serial adapter to connect the arduino to the raspberry? The raspberry hat an onboard uart at /dev/ttyAMA0. I am using the internal uart and cannot reproduce this kind of error.

:+1:

What version openhab runtime and add ons do you use?
How many nodes do you have and how long time they are working fine without restart rpi?
Please can you upload your config files?

1.6.2 or 1.7.0 didn't switch on-off my relays but logs seems ok:

I connected nano pins VIN+GND+TX+RX to RPI 5V+GND+TX+RX , (TX->TX , RX->RX)

[TimO]

I've upgraded to the nightly of OpenHab 1.7.0 to see if I'm able to reproduce your problem.
My modified OpenHab 1.6.2 did ran for a few weeks without problems. I'm using an Arduino Nano connected to an old laptop, so no RPi and the FTDI from the Nano.

[C.r.a.z.y.]

@TimO please can you share Openhab files?
+My relay powered from nano icp headers maybe this makes trouble for wifi , i will change this and give update.

[C.r.a.z.y.]

@TimO

I installed this https://github.com/lurch/rpi-serial-console
pi@raspberrypi ~ $ rpi-serial-console status
Serial console on /dev/ttyAMA0 is disabled

Now my nodes are working perfect when i use manual button or ui but my logs are not correct

My config:

add on : org.openhab.binding.serial_1.6.0.201411271703.jar
String Arduino "Arduino" { serial="/dev/ttyUSB0" }

As you see there are "fails" but nodes are working.

@C.r.a.z.y. : I don't think this problem is related to OpenHab.

In my case the output looks like this:

2015-03-09 11:50:45.780 [INFO ] [runtime.busevents             ] - Light_Corridor_First_Floor received command ON

ArduinoUpdate -> 0;0;3;0;9;send: 0-0-102-102 s=2,c=1,t=2,pt=0,l=1,st=ok:1

OpenHab does not interpret the response (fail/ok). It is something I need to work on.

[C.r.a.z.y.]

@TimO I think so maybe rpi usb problem...

Is there a newer file for org.openhab.binding.serial_1.6.0.201411271703

[TimO]

@C.r.a.z.y.: Yes, I'm using the current NIGHTLY from cloudbees: https://openhab.ci.cloudbees.com/job/openHAB/

You need to change:

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

To:

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

The communication between the Gateway and the Controller/OpenHab seems to work fine, but the answer from the Gateway is the wrong one. So changing the binding won't solve this problem.

What is the serial output of the receiving node?

[C.r.a.z.y.]

@tim @hek
Hek adviced me to download current 1.4 v in a topic and i did. I was using 1.4 which downloaded 2 months ago.
After that;
My old node's sketch(or api) was not the same with my new serial controller sketch 1.4
I reupload sketches to every node and gateway still I am not sure with this solution but today my nodes worked fine.

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.
