[Tutorial] openHAB with serial gateway

TimO

As it is now possible to use a serial gateway with openHAB I've written a simple (as simple as possible) entry tutorial.

What do we need?

a MySensors serial gateway
a linux system (like a RPi, example based on Ubuntu)
a MySensors sensor (for example with a DHT22 and a fixed NODE_ID of 101)

Where to start?

Start with the serial gateway.

Build it: http://www.mysensors.org/build/serial_gateway

If you see something like this in the serial monitor for arduino you're done:

 0;0;3;0;14;Gateway startup complete.

Connect the serial gateway to the linux system and execute "dmesg". You should see something like:

[  186.047748] usb 2-1.5: new full-speed USB device number 7 using ehci-pci
[  186.147030] usb 2-1.5: New USB device found, idVendor=0403, idProduct=6001
[  186.147036] usb 2-1.5: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[  186.147040] usb 2-1.5: Product: FT232R USB UART
[  186.147044] usb 2-1.5: Manufacturer: FTDI
[  186.147047] usb 2-1.5: SerialNumber: A40360T2
[  186.149618] ftdi_sio 2-1.5:1.0: FTDI USB Serial Device converter detected
[  186.149659] usb 2-1.5: Detected FT232RL
[  186.149663] usb 2-1.5: Number of endpoints 2
[  186.149667] usb 2-1.5: Endpoint 1 MaxPacketSize 64
[  186.149670] usb 2-1.5: Endpoint 2 MaxPacketSize 64
[  186.149673] usb 2-1.5: Setting MaxPacketSize 64
[  186.150205] usb 2-1.5: FTDI USB Serial Device converter now attached to ttyUSB0

As we see the serial gateway is now accessible through "ttyUSB0" like: /dev/ttyUSB0. But the Number may change. It depends on the FTDI Chip and could also be something like "/dev/ttyACM0".

But we don't want to look for the correct name after every reboot or after we plugged out and in the serial gateway, so we add the following in "/etc/udev/rules.d/99-usb-serial.rules"

SUBSYSTEM=="tty", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", ATTRS{serial}=="A40360T2", SYMLINK+="ttyUSB99"

Look at the output from "dmesg" above and change "0403", "6001" and "A40360T2" according to your hardware.

Now plug out and plug in the serial gateway.

The serial gateway will now be accessible through "/dev/ttyUSB99".

Install openHAB

It is important to install a version like or above 1.7.0. This version is not stable yet so download a snapshot from cloudbees:

https://openhab.ci.cloudbees.com/job/openHAB/

You need:

distribution-1.7.0-SNAPSHOT-addons.zip
distribution-1.7.0-SNAPSHOT-runtime.zip

Move to the "/opt" directory and extract the files:

cd /opt
mkdir openhab
cd openhab
unzip /tmp/distribution-1.7.0-SNAPSHOT-runtime.zip
cd addons
unzip /tmp/distribution-1.7.0-SNAPSHOT-addons.zip org.openhab.binding.serial-1.7.0-SNAPSHOT.jar

We will keep it simple and just use the serial binding.

Configure openHAB

At first we need to configure openHAB to use the serial binding to connect with the gateway. So we switch to the "configurations" directory:

cd /opt/openhab/configurations

There we create a file named "demo.items" in the "items" directory:

vi items/demo.items

Insert the following content:

String Arduino "Arduino" { serial="/dev/ttyUSB99@115200" }
Number          livingTemp01                            "Temperatur [%.1f °C]" <temperature> 
Number          livingHum01                             "Feuchtigkeit [%.1f %%]" <temperature>

We keep it simple and just assume we just want to read out a DHT22.

Start up openHAB with "/opt/openhab/start.sh". You should see something like:

2015-04-02 20:05:30.731 [INFO ] [runtime.busevents             ] - Arduino state updated to 0;0;3;0;14;Gateway startup complete.

If that is the case: very good!!

Now we need rules that reads the information that is received by openHAB via /dev/ttyUSB99 and show it.

vi rules/demo.rules

            }   
        }
end

Wow, that is hardcore! Are you still with me? Luckily there is not much to change for start.

There is a mapping, that you may change or want to extent:

// Mappings
var HashMap<String, String> sensorToItemsMap = newLinkedHashMap(
    "101;0;"            -> "livingHum01",
    "livingHum01"       -> "101;0;",
    "101;1;"            -> "livingTemp01",
    "livingTemp01"      -> "101;1;"
)

Where "101" is the NODE_ID of my DHT22 Sensor. I'm using hardcoded NODE_IDs, so if your sensor has another NODE_ID already, just change the mappings in the configuration. The "0" and "1" after the "101" is the childId. Change that too if you must. Just look at the Arduino code of your sensor.

Start openHAB if it is not already running and look for the output.

     2015-04-02 20:19:47.057 [INFO ] [runtime.busevents             ] - Arduino state updated to 0;0;3;0;9;read:101-101-0s=0,c=1,t=1,pt=7,l=5:44.7 
     101;0;1;0;1;44.7

2015-04-02 20:19:47.114 [INFO ] [runtime.busevents             ] - livingHum01 state updated to 44.7
Hum item: livingHum01 hum: 44.7

If you see something like the above it is still working!

*Nearly done! *

Know we want to show the information in a sitemap. We just create one with:

vi sitemaps/demo.sitemap

Content:

sitemap demo label="Hauptmenü"
{
  Frame label="Wohnzimmer" {
    Text item=livingTemp01
    Text item=livingHum01
  }
}

We keep it simple here!

If OpenHAB is not running start it and fire up your favorite browser and open

http://localhost:8080/openhab.app?sitemap=demo

For further information have a look at this thread: http://forum.mysensors.org/topic/655/serial-gateway-connection-to-openhab/2

Great Post Tim

Nice tutorial. I discarded my own incoming rules and am now using this solution. I have extended the rule by a few additional sub types:

if (subType == V_LIGHT_LEVEL){
                    postUpdate(sensorToItemsMap.get( nodeId + ";" + childId + ";"), msg)
                    println ("Light item: " + sensorToItemsMap.get( nodeId + ";" + childId + ";") + " light: " + msg )
                    }
if (subType == V_VOLTAGE){
                    postUpdate(sensorToItemsMap.get( nodeId + ";" + childId + ";"), msg)
                    println ("Voltage item: " + sensorToItemsMap.get( nodeId + ";" + childId + ";") + " voltage: " + msg )
                    }
if (subType == V_LOCK_STATUS){
                    var String lockstatus="OPEN"
                    if (msg=="1"){
                        lockstatus="CLOSED"
                    }
                    postUpdate(sensorToItemsMap.get( nodeId + ";" + childId + ";"), lockstatus)
                    println ("Door/Window item: " + sensorToItemsMap.get( nodeId + ";" + childId + ";") + " Status: " + lockstatus )
                    }
if (subType == V_TRIPPED){
                    var String tripped="OFF"
                    if (msg=="1"){
                        tripped="ON"
                    }
                    postUpdate(sensorToItemsMap.get( nodeId + ";" + childId + ";"), tripped)
                    println ("Button/Contact item: " + sensorToItemsMap.get( nodeId + ";" + childId + ";") + " Status: " + tripped )
                    }
if (subType == V_LIGHT){
                    var String light="OFF"
                    if (msg=="1"){
                        light="ON"
                    }
                    postUpdat(sensorToItemsMap.get( nodeId + ";" + childId + ";"), light)
                    println ("Light item: " + sensorToItemsMap.get( nodeId + ";" + childId + ";") + " Light: " + light )
                    }

Great post. Love the hashmap idea, much better then how I was doing it.
Just wanted to point out that on my beaglebone I had add the serial port parameter to the /etc/init.d/openhab file or to the /usr/share/openhab/start.sh depending on your setup.

-Dgnu.io.rxtx.SerialPorts=/dev/ttyO4

Im sure it has been covered elsewhere, but to enable other serial ports on the beaglebone you need to edit the /boot/uEnv.txt file and add the following to the optargs line:

capemgr.enable_partno=BB-UART4

This allows you to hook your arduino to P9_11(RX) and P9_13(TX) pins.

I think I'm going to try setting this up soon. I've been using the MQTT gateway but this would be simpler I think.

Any advice for switching from MQTT to serial in openhab.

I think I need to update openhab to use the 1.70 version but I don't think that would be too hard.

TimO

Can't give you an advice according the switch from MQTT to serial gateway.

Upgrading to 1.7.0 is no big deal, just save the configurations folder. I suppose it is possible to use the 1.7.0 snapshot serial binding, with an older version of the openHAB runtime.

I am using openHAB 1.6.1 with this rule. Works without problems. You need to compile the gateway with 9600 baud in config.h because openHAB 1.6 has a fixed baud value for the serial communication.

@TimO Thank you very much! I could not get the Symlink to work at first, but then I fould this, maybe it can help other Raspberry Pi owners.

@Jan-Gatzke I tried to connect a different sensor (RelayActuator) to my Gateway, added it to my .items, .sitemap and added your V_LIGHT routine in my .rules, but no success. Did I miss anything?

Thanks to all of you
Flo

Jan Gatzke

@schudoel These rules do only handle incoming messages from the sensor nodes. If you want to switch a relay you need an additional rule which sends the command to the the serial device.

schudoel

@Jan-Gatzke Thank you! I had a rule for the command, but it did not work out as I wanted. I think I had a typo in the code, but I could fix it. Are there any log files I could use for debugging the rules?

                    }
		
                }
            }   
        }
end

rule "livingRelay Switch Rule"
    when
        Item livingRelay changed
    then
        switchOperation.apply(livingRelay, Arduino, sensorToItemsMap.get("livingRelay"), V_LIGHT)         
end

and it's working like charm.

Was working ... I do not know why, but after I changed the power cables of the sensor, it stopped working correctly. Serial output:

send: 101-101-0-0 s=1,c=0,t=3,pt=0,l=5,st=fail:1.4.1

I do not have a decoupling capacitor to test whether it could solve my issues, but my hum/temp sensor and gateway do not have one either and are still working perfectly. I have tried to find any information on those fail messages, but wasn't successful. Do you have any suggestions?

Jan Gatzke

@schudoel You can have a look at the command line output of openHAB. Just start it via start.sh instead of the init script.

Are you sure your cabling is 100% ok?

schudoel

@Jan-Gatzke Yes, the command line of openHAB is always open. Wiring was okay. I bought some capacitors yesterday and added one 4.7uF to every nrf24l01+, now it is working again

Tango2

Not having much linux experience, I'm struggling with getting my serial gateway communicating with openHAB. If I install 1.7.0 in the /opt directory (entirely) this works, however I don't know how to get 1.7.0 installed after having installed 1.6.2 via apt-get - I tried replacing the files in each directory with the updated 1.7.0 files but 1.6.2 runtime is still starting automatically on boot in the openhab.log file.

I'm also reading that 1.7.0 may not be necessary for this to work, however with 1.6.2 running my USB port is not recognized in openhab - is that possibly due to the port speed being set at 115200 like @Jan-Gatzke mentioned above?

@Jan-Gatzke

I am using openHAB 1.6.1 with this rule. Works without problems. You need to compile the gateway with 9600 baud in config.h because openHAB 1.6 has a fixed baud value for the serial communication.

TimO

The support for a baudrate of 115.200, which is used by the MySensor serial gateway, is available since 1.7.0 in the OpenHab serial binding.

You're able to remove the old version with "apt-get remove ...", no need to replace the files. Just use the installation in /opt.

Tango2

Thanks @TimO. I got everything running in /opt (@9600, but I can change that later), and am receiving humidity/temp stats from my one sensor module running on a nano with DHT22 connected. I need to go through and do some major cleanup now, and also figure out how to convert to from F to C for the temp. It seems like the stock code has provisions for that, however I haven't quite figured out how to enable the change yet.

Thanks for the help - I look forward to implementing more of these sensors.

guzzler

I am having trouble getting Arduino Nano detected by Raspberry Pi via USB.

I could see this in the monitor when I selected the correct baudrate:

Initially while flashing serial gateway sketch to nano from Mac I had some trouble to get the right drivers. After following this post it worked fine. Is this to do with chinese knock offs?
http://kiguino.moos.io/2014/12/31/how-to-use-arduino-nano-mini-pro-with-CH340G-on-mac-osx-yosemite.html

Also I installed Arduino sketch on Raspberry pi with apt-get install arduino: When I launch Arduino and go to Tools>Port is disabled.

Is there anything I need to do on RPi so it can detect Arduino Nano knock pff?

TimO

I followed the link to the page you mentioned and from there to the chinese page.
There is a zip-file for linux too, maybe you need to install the driver on the RPi too?

http://www.wch.cn/download/CH341SER_LINUX_ZIP.html

Just a guess.

guzzler

Thanks @TimO .

I have been trying to make and load that driver but cannot get hands on 3.12.28+ kernel source. It wont compile without it.

I am wondering how come no body has come accross this issue, I bought my Arduino Nano from one of the links on mysensors store.

Jan Gatzke

I don't understand why everybody is using an USB connection for the serial gateway when openHAB is running on a raspberry pi. The pi has a rock stable uart with 3.3V logic. There is no need to convert the arduinos uart to USB. Just connect RX to TX and TX to RX. Connect ground to ground and VCC of the arduino to the 3.3V pin of the pi and you are done. The official openHAB wiki contains instructions on how to use the onboard uart of the pi: https://github.com/openhab/openhab/wiki/Serial-Binding

guzzler

@Jan-Gatzke Thanks for the pointer. I will try that.

I think the reason is lack of understanding. After reading sea of information I am able to pull together the basic architecture of how this would work.

poeml

@guzzler I stumbled over the same issue. The FTDI chip on my Nano is correctly recognized as USB device when I attach it to the Raspi. However, when I reboot the Raspi, the device is not there. I need to unplug and replug it.

That's not normal behaviour of an USB device. And it's quite hindering deploying the Nano as gateway via USB-serial. Maybe it has something to do with automatically performed reset on the Arduino Nano board??

(The hint about attaching directly to serial is great. Noted for later.)

poeml

@poeml more precisely, the Nano's FTDI chip connects to the booting Raspberry, but instead of registering a single device there are 4 (!) log lines claiming registering 4 devices (very funny), and none of the devices are bound.

May 23 23:16:21 bramble kernel: [    3.738087] usb 1-1.5: new full-speed USB device number 5 using dwc_otg

May 23 23:16:21 bramble kernel: [    5.268161] usb 1-1.5: new full-speed USB device number 8 using dwc_otg

I don't find a way to trigger re-registering the device, or power-cycle the USB port, via software. I can only power-cycle the whole USB bridge, which means that the LED goes out (the Ethernet chip is switched off as well...) and LED goes on again, but with the same faulty registering as when booting.

 # cat reset-usb
#!/bin/bash
echo 0 > /sys/bus/usb/devices/1-1/authorized
sleep 1
echo 1 > /sys/bus/usb/devices/1-1/authorized

Unplugging and replugging always works.

For the record: Raspberry Pi version 2 with the 4 USB ports, just updated to Debian 8.0 (Jessie). I didn't check with Debian Wheezy if it worked then. The Nano was linked from MySensors store I believe and works great otherwise. I have two of them and both have the same problem (or the Raspi's USB stack has the problem, who knows).

gizmosensor

Great tutorial! Thank you for putting this together.

My controller is on RPi, and I'm using a Nano for mySerial gateway with the USB plugged into the RPi. When I specify the port as follows I get the following message

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

org.openhab.model.item.binding.BindingConfigParseException: Could not open serial port /dev/ttyUSB0@115200: Serial port '/dev/ttyUSB0@115200' could not be found. Available ports are:
/dev/ttyUSB0

MySensors.h has the following
#define BAUD_RATE 115200

I tried taking out @115200, I see openhab.log showing it trying to read garbage and the rules failing. So, I', thinking the garbage is because openhab is not reading it with the right baud rate. However, openhab on the RPi doesn't like /dev/ttyUSB0@115200

Any ideas anyone?

Jan Gatzke

Your Version of openHAB is to old. You need openHAB 1.7 to set the baud rate with @xxxxx. Update openHAB or recompile the gateway sketch with 9600 baud in config.h.

gregl

@poeml Just a thought - try connecting the nano to the rpi via a USB hub.

gizmosensor

@Jan-Gatzke That seemed to work. I'm getting readable data now. Thanks!

I also set the nodeId to 15 (The above example assumed it was set to 101), as follows in the sensor

gw.begin(NULL, 15);

I adjusted the mapping accordingly in the mapping, as specified in the tutorial using 15 instead of 101. The following is now being output from event.log

2015-05-31 22:18:33 - livingTemp01 state updated to 22

Dear all,

I've stuck. Please help me to understand.
Currently I have a serial gateway and openHAB 1.7. I've managed to get controller working and send commands to openhab installed on Windows.

Now I need to understand how to convert commands from the gateway.

I have a rule

rule "Arduino sends to Openhab"
    when
        Item Arduino received update
    then
        var String lineBuffer =  Arduino.state.toString.split("\n")
        for (String line : lineBuffer) {
            var String[] message = line.split(";")
            var Integer nodeId = new Integer(message.get(0))
            var Integer childId = new Integer(message.get(1))
            var Integer msgType = new Integer(message.get(2))
            var Integer ack = new Integer(message.get(3))
            var Integer subType = new Integer(message.get(4))
            var String msg = message.get(5)
			
            if(msgType == 3 ){
                if (subType == 9){
					sendCommand(Arduino_Motion1, ON)
					pushover("Motion Detected", -1)
		} } }			
end

items:

String Arduino "Serial" {serial="COM4@115200"}
Switch Arduino_Motion1 	"Motion" <siren>

and a sitemap

sitemap home label="Home"
{

Frame label="Serial" {
Switch item=Arduino_Motion1 label="Motion Sensor"
} }

So in debug I have following:

2015-06-01 12:51:29.154 [INFO ] [runtime.busevents             ] - Arduino state updated to 0;0;3;0;9;read: 1-1-0 s=1,c=1,t=16,pt=0,l=1:1
1;1;1;0;16;1

2015-06-01 12:51:29.156 [INFO ] [runtime.busevents             ] - Arduino_Motion1 received command ON

So I've found an example of temp sensor but not the motion...
Pushover sends me notifications when motion sensor send 0 to the gateway every minute or so. (0;0;3;0;9;read: 1-1-0 s=1,c=1,t=16,pt=0,l=1:0). I don't understand how can I separate last 0 from 1.
I know I'm on a last step, please help

Thank you!

almj

Thanks for help
Figured out it by myself

Jan Gatzke

Would you mind to share the solution?

C.r.a.z.y.

@TimO Hi do you work with Openhab 2.0? I tried to install it and couldnt create a binding, its very hard for me. I need auto Discovery of mysensors with 2.0

Jan Gatzke

A 2.0 binding would be great. How far did you get?

TimO

Last time I've tested Openhab 2.0 there were some (well known) serious bugs and it still is only an alpha version. An MySensors binding for Openhab would be really cool and I will give it a try, but not for the 1.X Version, because of the lack of autodiscovery mechanisms in Openhab itself and because I think it is a little bit too early for Openhab 2.0.

C.r.a.z.y.

@TimO ok 2.0 alpha...

An idea for 1.x; Ready-Discovery ?
We write 250 mysensors items like ID=1-30 for switches, 31-50 for contacts, 51-70 for motion etc... if item is available then sitemap will show them.

Is there anyway to create rules on frontend? Maybe IFTTT + MySensors goes well..

C.r.a.z.y.

@TimO

Hi

Please check this http://forum.mysensors.org/topic/1543/universal-gateway-for-315-433mhz-devices/2

Is there anyway to use directly 433 with openhab --- serial gateway will be 433 receiver and transmitter (without mysensors lib and devices)

ewgor

hi,
just wanted to ask if anybody developed l154 work here http://forum.mysensors.org/topic/655/serial-gateway-connection-to-openhab/31? any arduino code for the node point with a few relays and a few sensors?
thanks!

gigaguy

How to I add I_BATTERY_LEVEL to the openhab rules? Being internal I wasnt sure if hashmap would do it.

Something like this? Where Item is NodeX_Batt

        // Internal Command
        if(msgType == 3){
            if(subType == I_BATTERY_LEVEL){
                    postUpdate("Node" + nodeId + "_Batt, msg)
                    println("Node" + nodeId + "_Batt:" + msg)
                }}

John Connolly

This is a BRILLIANT tutorial. Up and running with a single temp/humidity node in minutes. Thanks so much.

I built a second node (identical simple DHT22 temp/humidity) and set the Node-id to 110. I'm just wondering how to add the second node into OpenHAB? I have confirmed that openhab is receiving the signals from the second node correctly, but not quite sure about the OpenHAB rules, sitemap and items configs for a second node - that is identical in every way save for the Node ID and different item names. I've simply duplicated all of the code in the relevant config files, changed the item names and added four extra lines to the mapping to map the second 110 node. When I do this I get no data from either of the nodes. If I comment out my changes, I get the values from my first node just fine.

Can anyone with multiple nodes post a link to their configs so I can see what I might be doing wrong? Cheers.

John Connolly

Scratch that...I figured it out. In the rules file, I needed to add a extra comma after the first chunk of mapping. As it stood, I presume it failed to process the whole rule, as there was a syntax error (missing comma) which mean't the 'list' of mappings were incomplete. Added a comma and all was right once again.

Dave Dan

Hi guys,

I'm running in an interesting issue here, posting to see where I'm missing a step.

I have a Serial Gateway, connected to openHAB and working without issue. I see messages from the arduino Monitor and I can see the messages in openHAB without issue.

I'm running openHAB on Raspberry PI. arduino connected to PI by USB (on serial port /dev/ttyUSB0) declared as below:

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

The problem that I'm facing is related to the parse process ( I think ).

Message sent from my node:

send: 124-124-0-0 s=0,c=1,t=1,pt=7,l=5,sg=0,st=ok:32.0

with this code:
This is the section of the arduino sketch that I'm using to send the Humidity status:

float humidity = dht.getHumidity();
  if (isnan(humidity)) {
      Serial.println("Failed reading humidity from DHT");
  } else if (humidity != lastHum) {
      lastHum = humidity;
      gw.send(msgHum.set(humidity, 1));
      Serial.print("H: ");
      Serial.println(humidity);
      numAttemptsHum = 0;
  }  else {
    Serial.print("Attempt ");
    Serial.print(numAttemptsHum);
    Serial.print("/");
    Serial.print(MAX_NUM_ATTEMPTS_HUM);
    Serial.print(" - Same Humidity level presented");
    Serial.print(" (Previous:");
    Serial.print(lastHum);
    Serial.print(" vs Current: ");
    Serial.print(humidity);
    Serial.println(") - not sending");
    numAttemptsHum ++;
    if ( numAttemptsHum > MAX_NUM_ATTEMPTS_HUM ) {
      lastHum = 0;
      numAttemptsHum = 0;
    }
  }

(it's based on the Humidity & Temp example with minor changes to avoid traffic witout reducing the sampling frequency but with consistent updates based on a specific threshold.).

Message received in openHAB:

13:27:54.142 [DEBUG] [b.serial.internal.SerialDevice:194  ] - Received message '0;0;3;0;9;read: 124-124-0 s=0,c=1,t=1,pt=7,l=5,sg=0:31.0
' on serial port /dev/ttyUSB0

So at this point I see that all messages are type 3 ( not 1 as in the above example ).

That message updates my openHAB item, as per this example I have a rule that descompose the original message ( no modifications done yet to the one posted here ).

So, when I finally get to the core msg ( the one that in this example is directly assigned to the openHAB item ) the value is:

124-124-0 s=0,c=1,t=1,pt=7,l=5,sg=0:31.0

instead of the 31.0 that I was expecting.

Any ideas?

(happy to provide more sections of code if needed, didn't want to put everyting here to avoid garbage)

Thanks in advance for any help.

hek

@Dave-Dan
0;0;3 means a debug message.. you can throw these away. Shouldn't be processed by your controller.

Dave Dan

@hek
hey hek, thanks for the quick reply.

so that means that if i disable DEBUG in the arduino skech I'll remove that part of the message?

hek

Yes, they disappear when disabling DEBUG.

Dave Dan

Ok cool.
That means that I'm doing something else wrong bc I still see that part after disabling DEBUG.

I'm curious on why having the same sketch + openHAB rule from thia thread I xan make it work ...

Will review carefully because sounds weird for me.

Thanks!!!!

Hi TimO,
I want to make a permanent USB setting for my Radberry and I follow your tutorial here.
In my etc/udev/rules.d I have two documents: 40-scratch.rules and 99-input.rules and I don't know where to make the needed modifications as you show in this tutorial.
The file you point to make the modifications has another name and I can't figure where to add the vendor, product and serial no for my arduino. Shall I make a new file called 99-usb-serial.rules and to write in it the ATTRS{idVendor} and the rest of them according to my dmesg as you say here above or to do that in one of the two files I have?
Thanks!

ewgor

Hi! Can somebody please help here? I got stuck with my openhab server on my raspberry!
By now I was starting the server by:

Sudo /opt/openhab/start.sh

But I wanted more, to make it auto start on reboot so in case of power failure to auto start when the power is back. Therefore I followed some tutorials found on the www and I got it done, now the server starts alone but I cannot do anything from web page or from my phone. I also can't see the temp and humidity on the web or phone!
The question is how to stop this server? I tried different commands found on the internet but non of them can stop this invincible server I have lunched
I tried to stop it, remove, delete... Nothing works!
Is there any way to remove everything from my raspberry pi and to start it all over again with all the installation as for windows ? Format the partition, install the noobs again and so on?
Thanks.

TimO

udev: Just create the new file if it is not there yet. It should be processed automatically.
The best way to start a service in Linux is using an etc-script. You will find an example here: https://github.com/openhab/openhab/wiki/Samples-Tricks#how-to-configure-openhab-to-start-automatically-on-linux
The script will start OpenHab at boot and you're able to start/stop/restart with
```
/etc/init.d/openhab start
or
service openhab start
```

I'm having issues getting the ttyUSB99 fix to work.
I'm running openhab 1.7.1 and it was installed using apt-get.
My dmseg output looks like this

[10167.765598] usb 1-1.2: USB disconnect, device number 4
[10167.766311] ch341-uart ttyUSB0: ch341-uart converter now disconnected from ttyUSB0
[10167.766407] ch341 1-1.2:1.0: device disconnected

[10171.952514] usb 1-1.2: ch341-uart converter now attached to ttyUSB0

As you can see there is no SerialNumber here, but I found it using

pi@raspberrypi ~ $ udevadm info -a -n /dev/ttyUSB0 | grep '{serial}' | head -n1
    ATTRS{serial}=="3f980000.usb

So I created a rules file looking like this:

pi@raspberrypi ~ $ cat /etc/udev/rules.d/99-usb-serial.rules
SUBSYSTEM=="tty", ATTRS{idVendor}=="1a86", ATTRS{idProduct}=="7523", ATTRS{serial}=="3f980000.usb", SYMLINK+="ttyUSB99"

I have disconnected and reconnected my gateway.
But starting openhab now just results in the following error:

2015-09-20 09:24:48.867 [ERROR] [i.internal.GenericItemProvider] - Binding configuration of type 'serial' of item ?Arduino? could not be parsed correctly.
org.openhab.model.item.binding.BindingConfigParseException: Could not open serial port /dev/ttyUSB99: Serial port '/dev/ttyUSB99' could not be found. Available ports are:
/dev/ttyUSB0

What can I do to resolve this?

Daniel Lindberg

Eventually solved it by just omitting SerialNumber, i.e.

SUBSYSTEM=="tty", ATTRS{idVendor}=="1a86", ATTRS{idProduct}=="7523", ATTRS{serial}=="3f980000.usb", SYMLINK+="ttyUSB99

I guess that could cause problems if I would attached more similar devices to my RPI, but I don't know if there is any point in having more than one gateway? (unless you have > 255 sensors I guess)

nikos1671

Hi,

I am new with mysensors and i am trying to make it work with openhab.
I have a soil sensor and with same copy paste from the forum i manage to sent the value on the openhab, now i am trying to translate the battery level on the opnehab side but i dont know how to do it. can someone help me please?? this is what i get on the openhab 0;0;3;0;9;read: 254-254-0 s=255,c=3,t=0,pt=1,l=1,sg=0:68
254;255;3;0;0;68 this is the battery value.
But i am lost on the rule how to decode the message.

Thanks
Nikos

I also would like to share my working default.rules + examples with you. Hope it can help someone.

https://gist.github.com/gersilex/13f39b3419427b35636a

TimO

Hi @nikos1671 !

You need to add an item to the hash map with nodeID 254 and childId 255.
In the rules section search for

// Internal Command
        		    if(msgType == 3){
        		        if(subType == I_SKETCH_NAME){
        		                println("Sketch name: " + msg )
        		                sketchName=msg
        		            }
        		        if(subType == I_SKETCH_VERSION){
        		                println("Sketch version: " + msg )
        		                postUpdate(sensorToItemsMap.get( nodeId + ";" + childId + ";"), sketchName+" " +msg )
        		                sketchName=""
        		            }
        		        }

As the battery status is an internal message, you need to modify this section. Add an if statement for I_BATTERY_LEVEL.

@TimO thank you

What i am doing wrong??
i am using the last rules from silex and i can parse the data from my sensebender temp and hum on openhab but i cannot make it with battery. here is my setup

// Mappings
var HashMap<String, String> sensorToItemsMap = newLinkedHashMap(

"3;1;"                 -> "Temp",
"Temp"					-> "3;1;",
"3;2;"                 -> "Hum",
"Hum"					-> "3;2;",
"3;255;"                 -> "Batt",
"Batt"			   		-> "3;255;",

the rule

if(msgType == M_INTERNAL){ // Internal Command
print("(INTERNAL)\t")
if(subType == I_SKETCH_NAME){
println("Sketch name: " + msg )
}
if(subType == I_SKETCH_VERSION){
println("Sketch version: " + msg )
}
if(subType == I_BATTERY_LEVEL){
postUpdate(sensorToItemsMap.get( nodeId + ";" + childId + ";"), msg)
println ("Batt item: " + sensorToItemsMap.get( nodeId + ";" + childId + ";") + " Batt: " + msg )
}

my.items
String Arduino "Arduino" { serial="COM3@115200" }

Number Temp "Temperatur [%.1f °C]" <temperature>
Number Hum "Feuchtigkeit [%.1f %%]" <temperature>
Number Batt "bataria [%.1f %%]" <energy>

and this is the logs of openhab

Can someone help me please??

Hi @nikos1671,

everytime I had that error was mainly because I forgot / add extra comma in the LinkedHastMap definition or something like that.

Can you please share the full openHAB rule?

nikos1671

Hi @Dave-Dan ,

i think i found the problem. i have 2 sensebender micro one with the original shiped firmaware 1.1 (node1) and one with the new one 1.3 (node3) as you can see in the logs of openhab the node1 its parsing the data on the openhab very good but the node3 throwing an error( Error during the execution of rule 'Decode incoming MySensors data': 5)

here is the rule that i use

The rule react fast and fill all the data (temp,hum,bat) on the openhab site for the node with the old firmware but with the new frimware i connect the batteries on the sensor and i must wait some minutes until the temp and hum appear on th site but the battery percent not,only after hours
Thanks
Nikos

Dave Dan

hey @nikos1671,

good to hear you have it under control.

Also, please take a look to the 'sensorToItemsMap' definition. If I remember correctly, the last item in the last item, otherwise the compiler is waiting for another item.

This is something that happened to me every time I include any new item (you know, copy & paste ... bad thing :P).

The fact that you have to wait hours to get the battery status is odd. When I restart one of my nodes ( one with battery level) I have the information inmediately available, well ... as soon as the node sends the information, and fully refreshed in openhab site.

it's true I've had different update speeds but basically because I did my first tests with ah Raspberry Pi 1 and now I have all the system working in a Pi 2 ... so goes faster (very much).

SiLeX

Hey guys, on my Raspberry Pi 2 the first rule execution takes about 15 seconds. If you have changed the rules file, the xtent logic has to be re-compiled to java code again. But after the first rule execution it takes only about 10-50ms for execution.

Also, @nikos1671 I would turn off the DEBUG mode on your gateway. Receiving data works and this is what you would debug. You see incoming data without debug, too so you can securely get rid of it

nikos1671

Hi ,

I think the problem is this msg 3;255;4;0;0;FFFFFFFFFFFFFFFF0300 is this something with the OTA firmware? i think the rule dont recognise this msg and give an error (Error during the execution of rule 'Decode incoming MySensors data': 5). Can the author of the rule please confirm if this it the problem of the error??

SiLeX

@nikos1671 In case of unhandled messages (when there is no openhab item assigned to this nodeID;childID;-combination in your sensorToItemsMap), they will just be ignored (and print the data field).
This happens here in the code: https://gist.github.com/gersilex/13f39b3419427b35636a#file-default-rules-L211

This will look like this:

3;255;4;0;0;FFFFFFFFFFFFFFFF0300
No item matches nodeId=3, childId=255. Data received: FFFFFFFFFFFFFFFF0300

However, this was never tested with debugging enabled on the Gateway. This is why I asked you to disable debugging and recompile/reupload the code to your gateway arduino without the DEBUG flag inside MyConfig.h.

There is a know problem which is not catched currently:

Data can only be decoded, if the String has exactly 6 fields, seperated by a semicolon.

Please go and try to disable the DEBUG on your gateway arduino.

Can someone help me? I want to integrate a motion sensor in OpenHAB but I don't know how to distinguish between the motion start and end. here's my openhab console log:

HenryWhite

Can somebody help..?

Dave Dan

Try removing DEBUG in the Serial GW and review messages.

I receive a 0 or 1 depending if the motion is detected or the sensor is resetting to normal status.

HenryWhite

@Dave-Dan i tried it, but the motion sensor is still sending only zero's.... even if it is not triggered.
I got these motion sensors: http://www.amazon.de/Pyroelectrische-Infrarot-Bewegung-Sensor-Detektor/dp/B008AESDSY/

HenryWhite

When I look at the serial monitor output for my motion sensor, it clearly gives me a "0" or "1" depending if movement is detected or not.

But when I look at the serial monitor of my gateway, it only receives the same message no matter if motion started (motion sensor serial monitor: 1) or ended (motion sensor serial monitor: 0)

TimO

@HenryWhite The node is requesting for an id and not sending any status. You'll need to define a static id in the sketch of your node:

http://www.mysensors.org/download/sensor_api_15#the-full-api

Look for "Starting up the library" and the "begin()" function.

HenryWhite

@TimO thank you so much! it works now. Any idea why i had to assign a static id? i thought the gateway should tell the node a dynamic id automatically..

TimO

@HenryWhite You're welcome. The id is assigned by the controller, in your case OpenHAB. There is a post in the forum about how to add a rule for id assignment, but I don't use it myself.

I have a real noob question, and I am way better with the electronics that I am the software. I can see my motion detector show up in my gateway, and in the events.log, so I know that I am getting to the Raspberry Pi I deployed opneHAB on.

Here's some detail:
So I have build the MySensors.org motion detector (and a separate temp/humidity sensor), loaded up the NRF24l01+ and PIR.
I created a gateway out of a nano with NRF24l01+.
I followed the tutorial on how to do the serial bindings.
I see in the terminal window runtime.busevents that the motion detector is detecting movement, and later changing back to 0, along with the other sensor I have, which is the DHT11 for temp and humidity.

My confusion is how this software all works to get just the information from the gateway to the screen.
I know you have to declare an item in the demo.items file, and that item needs to be in the sitemap to display. but I do not understand how you get the status from the gateway? Can someone point me to some simple examples that include the mysensor.org PIR sensor? How does the item declaration get the knowledge of the change that the gateway is receiving from the sensor? I have read through several documents and tutorials, but I am missing this bit of information.

lundebc

Ah, I finally see it, it was staring me in the face in the rules section. You identify via the msgType then assign in the rule. Doh!

poeml

@poeml following up myself, using an external, powered USB hub indeed fixed the problem. The USB adapter is now correctly usable after system bootup. (I use the official Raspberry Foundation hub, which promises to avoid issues with backpowering.)

HenryWhite

It just took me 2 hours to realize that you should not use

import java.util.*

when you want to use timer operations like

if (timer=! null) {
...
}

Without importing java.util.* , everything works as expected. Someone has an idea why this is the case? Can you reproduce my problem?

mark_venn

Thanks for this great post. Just what I need to get a handle on using openHAB with MySensors!

And also in the openhab.log file I get the following types of messages:

[DEBUG] [b.serial.internal.SerialDevice:225  ] - Received message '99;0;1;0;1;37.6
' on serial port /dev/ttyUSB99

But the rule is for some reason not initiated I guess as the println and logInfo i I've added to the top of the rule is absent from the logs. I can see from the tutorial and your posts that you get log information like below but these I cant find in any log.

[INFO ] [runtime.busevents             ]

Possibly I'm missing something in my logback.xml settings or perhaps there is some other reason to this which also might explain why my rule is not started. Perhaps its because I'm using a newer binding for the serial connection? (org.openhab.binding.serial-1.8.3.jar)

Any help would be much appreciated!

Update 1: Perhaps I'll try the mysensors binding and if I'm more successful with that approach I'll skip this serial binding altogether.

Update 2: Ok, I will be using the mysensors binding for the serial connection. I tried it last night and it just worked! And this serial binding approach also demands some quite extensive rule handling of the incoming messages which is not the case with mysensors binding. I think I read somewhere that the mysensors binding will also be available for Openhab 2.0 so hopefully I can continue using it also in the future.

My recommendation for new users of the serial gateway (who also uses openhap as a controller) is to go for the mysensors binding!

@TimO is it possible to send commands to actuators with this method? I have a LED Dimmer Actuator and don't know what I have to do in OpenHAB to send commands to this actuator over the serial gateway..

TimO

@HenryWhite: Yes it is possible.
Look at this example: https://forum.mysensors.org/topic/655/serial-gateway-connection-to-openhab/70
