    • [Tutorial] openHAB with serial gateway

      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 Β°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
      

      Content (that is the hardest part):

                  }   
              }
      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

      Hum item: livingHum01 hum: 44.7
      

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

      *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="HauptmenΓΌ"
      {
        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

      @gonzalonal : I found a solution for V_STOP! It will be available soon.

      But more important: @andreacioni is doing some great work improving the stability and performance of the binding!!

      I just wanted to let you know, that the binding is currently under heavy development. πŸ‘

    • openHAB 2.2 binding MQTT support

      Finally I'm able to present a first alpha release of the MQTT support of the OpenHAB2 binding.
      I've done some first tests with a RGB node and it looks good, but there is still some work to do.
      So this version is for the category "Don't try this at home!". πŸ˜‰

      Some important notes and things to test:

      • The binding uses the upcoming MQTT support in smarthome/OpenHAB2, not the old version 1 binding! They may work together, but we need to test that. If you're willing to test that, please let me now.
      • I've tested with OpenHAB2 snapshot #1099. I don't know how far it is compatible to old versions.
      • There is a PR in the smarthome repository to add the functionality of a MQTT broker to OpenHAB2, so a separate broker won't be needed in the future. The binding will be compatible with this addition.
      • I need to adjust logging.

      Instructions:

      1. Start OpenHAB2

      2. In karaf console:
        feature:install esh-io-transport-mqtt

      3. Download binding:
        wget http://www.oberfoell.com/openhab2/org.openhab.binding.mysensors-2.2.0-mqtt.jar

      4. Place "org.eclipse.smarthome.mqtt.cfg" in the /etc/openhab2/services or conf/services directory. New filename! (Wassn't my idea!) πŸ˜‰

      Example:

      mosquitto.url=tcp://192.168.2.3:1883
      mosquitto.user=user
      mosquitto.pwd=secret
      mosquitto.retain=false
      

      (Use it like the old mqtt.cfg)

      1. Configure MQTT broker via PaperUI
        0_1512124003255_Bildschirmfoto vom 2017-12-01 11-25-59.png
        or

      via *.things file

      Bridge mysensors:bridge-mqtt:gateway [  brokerName="mosquitto", 
                                              topicPublish="mygateway1-in",
                                              topicSubscribe="mygateway1-out",
                                              startupCheckEnabled=false ] {
                                              
      }
      
      1. Configure or discover things.

      That's it!

    • RE: Are folks here happy with Domoticz?

      I've tried Domoticz at the beginning and was amazed at how easy it is to setup.
      As other mentioned before I missed the flexibility and started with OpenHAB.

      I really like the flexibility of my setup:

      • MySensors Binding with three gateways attached (1x USB, 1x Ethernet RF24, 1x Ethernet RFM69)
      • Sonos
      • Influx / Grafana
      • node-red (for rules) https://flows.nodered.org/node/node-red-contrib-openhab or MQTT
      • Pushover
      • EbusD (heating)
      • Samsung TV
      • upcoming: Neato Vac
      • OpenHAB App

      I'm trying to combine the best out of all worlds which is really easy with OpenHAB.

      Examples:

      1. I've installed a (good looking) push button as a doorbell directly attached to the USB mysensors gateway and if the button is pressed a message is send via Pushover to our phones and the sonos in the livingroom is playing a sound while the sonos in the room of our baby girl is quite while she's sleeping.

      2. At (dawn - 120 minutes) the rollershutters (MySensors node) are closed, except the shutters of the doors to our terrace which will be delayed by 45 minutes. Additionally a light (433 MHz socket from hardware store) in the corridor and lights on the terrace (MySensors node) are switched on. Everything is switched off automatically at a given time. Rules are defined in node-red.

      3. Pressure of the heating system (Ebus) is below 1.3 bar --> send Pushover to phones

      The controller strongly depends on what you're up to. What devices are you using?

      If you're only using MySensors and maybe other devices that support Domoticz and don't need that much flexibility: stick with Domoticz. It's a good choice.

      If you have different devices, look into OpenHAB, if there's a binding.

      If you need the full flexibility go with node-red. There are many extensions available for node-red to support Pushover, Sonos .... so maybe that's the way to go.

    • RE: Serial Gateway connection to Openhab

      @CARSTEN I've compiled a modified version of the OpenHab Serial binding with a baud rate of 115200 as this is standard in mysensors.

      Download: org.openhab.binding.serial_1.6.0.201411271703.jar

      As @tboha suggested you currently have to manage all commands by yourself.

      I've attached my modified serial binding here. Please be aware, that all other configurations that depend on serial binding won't work with the modified version, because of the changed baud rate.

      I'm currently testing with this Serial Gateway:

      Serial Gateway

      Here is my OpenHab configuration for simple testing:

      demo.items: demo.items
      demo.rules: demo.rules
      demo.sitemap: demo.sitemap

    • RE: openHAB 2.0 binding

      I finally found some time to develop on the binding.

      A new version is available with the following changes:

      • On startup the binding will request I_VERSION from gateway to ensure its proper startup. Thanks @andreacioni for the PR!!

      • HVAC (V_VAR1, V_VAR2 ...) are now available. Thanks @Denke for the PR!!

      • The request for ACK feature is now available for testing. It works for light/status for me. If a message is NOT acknowledged by a node the binding retries to send the message five times. If no ACK is received after that the binding will try to revert the item to its old state. This only works, if a state is known (not NULL, for example at startup).

      Additionally I've tested the binding with multiple gateways (one EthernetGW, one SerialGW), works fine.

    • openHAB 2.2 binding

      Dear fellow openHAB2 binding users,

      it's time for a new release of the binding. The added functionality is low, but under the hood there were a few changes, so after the refactoring @andreacioni has done at the beginning of this year, I've done some refactoring too, with the objective to fullfil the regulations for an integration into the official openhab2-addons repository.
      I've tried to improve the readability of the configuration and of the code itself.

      This leads to an important point: The current release is not backwards compatible!!
      Whatever is configured (MySensors binding related) will not work anymore with the current release.

      But why?

      • nodeId & childId were Strings in the old bindings and now are Integer
      • skipStartupCheck was renamed to startupCheckEnabled

      If you've configured the things with the *.things file you just have to do two easy steps:

      1. Look for skipStartupCheck and switch it with startupCheckEnabled and reverse the logic (true to false and vice versa)

      2. Look for nodeId="123", childId="456" and remove the quotation marks ", so it will look like: nodeId=123, childId=456

      Copy the new jar file into the addons folder, start OpenHAB2 and you're good to go.

      If you've configured the things in PaperUI the easiest way is to delete all things and rediscover them. Of course in large installations this won't be much fun.

      I hope this won't happen again in further versions! :s

      Fixed in this release:

      • RGB & RGBW corrections
      • Removed bug that prevented autodiscovery of deleted things
      • mysensors.test fragment added / tests moved
      • Static code analysis
      • Move to 2.2.0 Snapshot

      The changes in functionality were small so there is no need to install the new version asap if you are able to forgo the above mentioned functionality.

    • RE: OH3 - MySensors Binding

      For those of you willing to help testing the OH3 integration here is a link:

      Jar Download

      Please don't forget to fulfill the requirements for mqtt und serial. Installation of bindings will do.

      What's working after a quick test:

      • binding loads in OH3
      • serial gateway receives messages (ethernet gateway should work too)
      • discovery is working

      What's not working:

      • MQTT gateway: it's broken some time and needs some tinkering

      Please let me know if you found some time to test the binding.

      @pikim Yes, I have tested with a blink example to light up an build in LED and that just worked as expected.

    • RE: Sensebender Gateway (SAMD21)

      @pikim Yes, I do have a sensebender gateway that i am planning to use for an energy Meter. I am currently struggling with the circuit but the sensebender is running fine (with the arduino IDE though).

      What did you copied where?

      @pikim I found no (quick) solution yet and I'm interested in that as well. πŸ™‚

      I've solved the dependency error and the package compiles fine, but I had no time for testing yet.
      If you're willing to test: Download

      Hey @fabyte and @ncollins!

      I just want you to know, that I'm still there, but out of time at the moment. My third child was born just recently and I don't have any time for the binding at the moment.
      I'm really sorry you had to reverse engineer the binding to add your code. That's awfully wrong.
      We need to create a new common base to continue the work on the binding.
      I was not able to add the binding to the official repo because of the formal requirements from the Openhab Team. I'm sure these requirements are needed, but I'm no professional in java. I struggled mainly at the nonnull annotations that are needed.

    • RE: OH3 - MySensors Binding

      @kerberos Interesting find. Haven't seen something like this till now. I suggest to delete the jar file, delete the cache and start over again.

      I haven't tested textual configuration, but this should work just fine and your problem occurred before the textual configuration is initialized.
