MQTT Broker gateway
-
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! -
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).

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.

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!

Typing from tablet => short Version
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
https://github.com/openhab/openhab/wiki/Explanation-of-items#itemtype -
Hi @dakky
well, some luck. I made a new map contact.map with
0=Closed
1=Open
-=unknownso 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=OFFAt 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
Soloam -
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.
-
That makes perfect seance, I was only mirroring the solution presented on the 1st post of this topic. I will try your approach!
Thank You
-
It didn't worked, the rule also changes when I receive the MQTT in openhab:
rule "Send Requst" when Item node2_sw2 received command then if(node2_sw2.state == ON){ sendCommand(node2_sw1,ON) } else{ sendCommand(node2_sw1,OFF) } endI don't believe this is a new problem to the forum, didn't any one made, a switch on the openhab with inptut and output.
-
Found the solution tanks to watou user in OpenHab Forum.
Switch node2_sw2 "sw2 send + recieve example" (node2,all) {mqtt=">[mysensor:MyMQTT/21/2/V_LIGHT:command:OFF:0],>[mysensor:MyMQTT/21/2/V_LIGHT:command:ON:1],<[mysensor:MyMQTT/21/2/V_LIGHT:state:MAP(1on0off.map)]"}The secret is in the :state: declaration on the MAP!
Thank you all
