      How can I implement MQTT for MQ-2 Gas sensor the correct way? In the mysensor sketch there is only one child ID and one V_VAR1 but 3 different outputs: LPG, CO and Smoke? I'm only receiving CO value and not all 3 in openhab.

        @kunall There is V_VAR1-5 actually

        V_VAR1	24	Custom value
V_VAR2	25	Custom value
V_VAR3	26	Custom value
V_VAR4	27	Custom value
V_VAR5	28	Custom value

        Personally I would set up each value you want as a S_CUSTOM if you can't figure out another sensor type that fits.

        For smoke you can use S_SMOKE
        For Air Quality S_AIR_QUALITY
        Not sure what you'd want to use for CO2 through

            How to Set-up MQTTGateway with OpenHAB

            What is MQTTGateway:
            MQTTGateway will act as a broker, a server. And any MQTT clients should be able to connect to it (Please let me know if you experience problems).
            MQTTGateway is a very simple implementation. It will not care if the client subscribes to anything or not.
            Every node package it receives it will publish to the client. Sketch name and version is also implemented.
            Most clients handle this well and just ignores messages it hasn't been subscribed yet.
            There are some settings in MQTT that can be good to take a look at.
            You will need to configure TCP_IP and TCP_PORT.
            MQTTGateway will also give nodes an ID between MQTT_FIRST_SENSORID and MQTT_LAST_SENSORID. The last position is stored in EEprom.

            As standard MQTT_SEND_SUBSCRIPTION is enabled. This basically means that the broker will send a empty payload to the node upon a subscribe package. This can be useful. Just keep in mind that you can receive empty payload packages.

            The MQTTGateway will also present its SketchName and SketchVersion.

            Lets get started!
            First follow https://github.com/openhab/openhab/wiki/Quick-Setup-an-openHAB-Server You can setup and try with DEMO configuration first.

            Then we need to unpack org.openhab.binding.mqtt into addons folder * NOTE (During development of MQTTGateway I found a bug inside openhab mqtt client which is solved in 1.6.0 nightly build. Use this nightly addon if you experience problems)

            • openhab.cfg
              All you need to do here is to add

              mqtt:mysensor.url=tcp://192.168.0.234:1883
              mqtt:mysensor.clientId=MQTT

            ClientID does not matter at all (just keep it short). And IP and Port is self explanatory.

            Now you can start OpenHAB, it will connect but nothing more will happen.
            This is because we hasn't subscribed to anything and OpenHAB will just ignore every incoming package.

            So here comes a sample configuration of OpenHAB.

            • items/test.items

              Group all
              Group node1 (all)
              Group node2 (all)
              Group sketch (all)

              Number node1_temp "Temp [%.1f °C]" (node1,all) {mqtt="<[mysensor:MyMQTT/20/10/V_TEMP:state:default]"}
              Number node1_humid "Humid [%.1f %%Rh]" (node1,all) {mqtt="<[mysensor:MyMQTT/20/11/V_HUM:state:default]"}

              Switch node2_sw1 "sw2" (node2,all) {mqtt=">[mysensor:MyMQTT/21/1/V_LIGHT:command:ON:1],>[mysensor:MyMQTT/21/1/V_LIGHT:command:OFF:0]"}
              Switch node2_sw2 "sw2 send + recieve example" (node2,all) {mqtt=">[mysensor:MyMQTT/21/2/V_LIGHT:command:ON:1],>[mysensor:MyMQTT/21/2/V_LIGHT:command:OFF:0],<[mysensor:MyMQTT/21/2/V_LIGHT:command:MAP(1on0off.map)]"}

              String sketch20 "Sketch name 20 [%s]" (sketch,all) {mqtt="<[mysensor:MyMQTT/20/255/V_SKETCH_NAME:state:default]"}
              String sketch21 "Sketch name 21 [%s]" (sketch,all) {mqtt="<[mysensor:MyMQTT/21/255/V_SKETCH_NAME:state:default]"}
              String sketch22 "Sketch name 22 [%s]" (sketch,all) {mqtt="<[mysensor:MyMQTT/22/255/V_SKETCH_NAME:state:default]"}
              String sketch23 "Sketch name 23 [%s]" (sketch,all) {mqtt="<[mysensor:MyMQTT/23/255/V_SKETCH_NAME:state:default]"}
              String sketch24 "Sketch name 24 [%s]" (sketch,all) {mqtt="<[mysensor:MyMQTT/24/255/V_SKETCH_NAME:state:default]"}
              String sketch25 "Sketch name 25 [%s]" (sketch,all) {mqtt="<[mysensor:MyMQTT/25/255/V_SKETCH_NAME:state:default]"}
              String sketch26 "Sketch name 26 [%s]" (sketch,all) {mqtt="<[mysensor:MyMQTT/26/255/V_SKETCH_NAME:state:default]"}
              String sketch27 "Sketch name 27 [%s]" (sketch,all) {mqtt="<[mysensor:MyMQTT/27/255/V_SKETCH_NAME:state:default]"}
              String sketch28 "Sketch name 28 [%s]" (sketch,all) {mqtt="<[mysensor:MyMQTT/28/255/V_SKETCH_NAME:state:default]"}
              String sketch29 "Sketch name 29 [%s]" (sketch,all) {mqtt="<[mysensor:MyMQTT/29/255/V_SKETCH_NAME:state:default]"}

            We also need to create a sitemap :

            • sitemap/test.sitemap

              sitemap demo label="Menu"
              Frame label="test" {
              Group item=node1 label="Temp hum node"
              Group item=node2 label="Switch node"
              Group item=sketch label="Sketch names"
              Group item=all label="Everything"
              }

            and a simple transformation file :

            • transform/1on0off.map

              1=ON
              0=OFF

            If everything worked and I didn't forget anything just fire up :

            http://[Openhab]:8080/openhab.app?sitemap=test

            After you restart one of your node's the data and sketch name should be visible.
            Openhab will forget everything after every restart. Use persistence to fix this (https://github.com/openhab/openhab/wiki/rrd4j-Persistence)

            how to run MySensors ( MQTT gateway) on the arduino due + Wiznet5100 + NRf24l01?
            Get the error:

              @celonunes Nope. I figured it out. In my openhab config file there was space prior to my MQTT related lines

              " mqtt:mysensor.url=tcp://192.168.1.134:1883"
              " mqtt:mysensor.clientId=OpenhabMQTT"
              Instead of
              "mqtt:mysensor.url=tcp://192.168.1.134:1883"
              "mqtt:mysensor.clientId=OpenhabMQTT"

              Removed the space and now I get my light sensor output value. I still don't get the sketch name coming through but I'll look into that later.

              @hooraysimpsons this solved my problem too! Everything else in my setup was a quick job but problem solving this issue took half a day. It should be more widely circulated..

                I dind´t read all comments so I hope this wasn´t answered before: I would like to know how to setup an arduino + NRF24L01 Node:

                • how to initialize the node
                • what should the Arduino sketch look like to start MQTT

                Thanks for your help!!

                  Ok,forget my last post, I have a new problem:

                  When I uplaod the EthernetGW Sketch to my arduino nano I can see MQTT messages coming in from one node int the arduino serial monitor. So now I uploaded the MQTTGW sketch to my nano because I would like to use openhab. But after uploading the sketch all info I get from serial monitor is "Started!", nothing else is showing up.
                  I can still ping the MQTT gateway but it seems like it´s not receiving any mqtt message, at least no the state of my node. Could you please help and support me here? Thanks in advance!

                  still learning...

                      Hello,

                      I have made this gateway with W5100.
                      Everything looks OK, except random connection failures.
                      Clients - MyMQTT (android), Openhab are loosing contact with the broker time after time.
                      The issue can occur every 5 - 60 mins.

                      Any ideas what could be the problem?

                      Thank you in advance.

                        Hi,

                        Was hoping someone could help a MQTT and openHab newb here. i have Openhab configured and running with Phillips Hue and Wemo, and trying to integrate MySensors. I build the 1.5 version MQTT gateway using the W5100 module, and all is working (can ping the gateway noproblem, and receiving data from a sensor). The problem is, i'm not sure how to add the line into the items and sitemap file....

                        Here is the output that I am getting from the MQTT serial monitor. The sensor I have connected is a 3-in-1 with motion PIR, and DHT22 temp/humid and a hard configured Node_ID of 3 (or, should be).

                        Can someone help me get the information to display in OpenHab? Please.

                          Contact contact_99        "Contact node 99 sensor 3: [MAP(de.map):%s]"        { mqtt="<[mysensors:sensor-gw1-out/99/3/1/0/16:state:MAP(mqttToCloseOpen.map)]" }

                          this is an item which
                          reads a message from mqtt broker:

                          • < input, reads message
                          • mysensors => mqtt connection as decribes in opnehab.cfg
                          • sensor-gw1-out => topics as configured in your mqtt gateway sketch
                          • 99/3/1/0/16 have a look at serial api: node 99, child 3 etc

                          I found it very helpful to subscribe myself to the mqtt broker and read the incoming messages there

                            Hi @dakky

                            Thanks for the help. So far, I can get my temperature and humidity to update, but I cannot get my motion sensor on the same node to update at all.

                            Here are the lines I have in default.items

                            /* MySensors MQTT */
Number		node1_temp					"Temp [%.1f °C]"     						(node1)		{mqtt="<[mysensor:MyMQTT/1/1/V_TEMP:state:default]"}
Number		node1_humid					"Humid [%.1f %%Rh]" 						(node1)		{mqtt="<[mysensor:MyMQTT/1/0/V_HUM:state:default]"}
Contact 	node1_motion        		"Motion Sensor 3: [MAP(1on0off.map):%s]"     (node1)	{ mqtt="<[mysensors:MyMQTT/1/2/V_TRIPPED:state:MAP(1on0off.map)]" }

                            And here is my default.sitemap file

                            Frame label="Sensor Data" {
        Text label="Sensors" icon="mysensors" {
		Group item=node1 label="Man Cave Climate" icon="temperature" 
		Chart item=node1_humid period=W refresh=10000
		}

                            And finally, this is what I am reading from screen when the message appear on the MQTT broker sketch. The node_id is 1, not 3 like I originally though.

                            Any ideas on what I am missing? Also, when trying to implement persistence, I went with MySQL as per directions here but the data doesn't actually go into the chart. Other than adding mysql to the openhab.cfg file, what else is there? The log isn't showing any errors from what I can see.

                            Thanks!

                              Contact items needs Open or Closed not On vor Off. Make a new map translating 0 to closed etc and it should work. or use the correct item: switch seems a better choice

                                Hi @dakky

                                well, some luck. I made a new map contact.map with
                                0=Closed
                                1=Open
                                -=unknown

                                so far the swtich now shows "Unknown" all the time; but no status updates from the sensor (even though it is showing in serial console as 1, and 0 when it is off).

                                Not sure why it isn't updating like it should now. Might have to reboot the server.

                                  Ok, got it. Had to do the following to my items and sitemap to get a PIR to work right:

                                  entry in default.items

                                  Switchnode6_motion	 "LR Motion Test [MAP(motion.map):%s]"  (FF_Living,All) {mqtt=">[mysensor:MyMQTT/6/1/V_TRIPPED:command:ON:1],>[mysensor:MyMQTT/6/1/V_TRIPPED:command:OFF:0],<[mysensor:MyMQTT/6/1/V_TRIPPED:command:MAP(motion.map)]"}

                                  and default.sitemap

                                  Text item=node6_motion label="PIR Test LR [%s]" icon="pir"

                                  And last, the transform file (named motion.map)

                                  1=ON
0=OFF

                                  At least now it registers the data in text as On or Off. Thanks again @dakky

                                    Is there a way to redirect all the messages from the serial console of the wifi gateway to some tcp port so they can be read via putty?

                                      Hello, sorry to reopen this post, but maybe someone can help me! I'm still waiting the arrival of my arduinos to make my nodes and gateways, but I already installed openhab to start configuring the layout and MQTT. All is working, I can post to MTQQ from openhab and used the tutorial on this post to make the same button send and recieve.

                                      The problem is that when I click the button with the code "sw2 send + recieve example" openhab enters in loop mode, it seems that keeps sending and reviving the same MTQQ request. I use MQTT.fx to test the MTQQ posts, and when I click the button, the program also crashes and takes my CPU to max.

                                      Can any one help me?
                                      Best Regards

                                        Hello, the problem persists, the map function keeps sending the same request over and over again, If I make a click in a few seconds my mqtt client is full of requests, over 500 with the same message. Wasn't it supposed to send only one message for click?

                                          I don't believe you can put both inbound and outbound mqtt messages in the switch definition. This is what creates the infinite loop since you are both sending and receiving on the same message topic. Every time the broker receives the message, it publishes it out to all subscribers. Since your switch item is also a subscriber it picks it up again and the loop continues.

                                          Use only inbound in the definition then either a rule and/or proxy item to handle the outbound command. Set your rule definition "when item received command". That way it will only fire when you click on the switch item in openHAB. If you use any other option, ie. received update or changed, it will also continue the infinite loop.

                                          Hope this makes sense.
