Please help! google map mqtt + owntracks on OH2?

Setup, Configuration and Use Runtime
21

Well, I think my set-up is fundamentally different than yours…

I use OwnTracks on iPhone, sending the positions to my rPi server running MQTT at home via port forwarding in my Internet router, then storing these positions in OwnTrackRecorder (OT-Recorder).

You seem to have a cloud service provider in between it all; meaning there could be other problems I cannot see / understand in your system.

The way I build my system with OH is: start small… and progress step by step.
E.g. I installed OH, then MQTT. Then OT on the iPhone and the OH OT binding, and made it work on the local network first (meaning, no port forwarding required).
Then I opened the port… after this worked, I installed OTR.

I have since removed mqttitude binding, and work only with MQTT in OH.

I do not believe that I am able to help you further, given our set-ups are different.

OK thanks for replying
May be I’ll backup and follow your route
Firstly, let’s make it talk within local network first.
I installed Owntracks (mqttitude binding) already. I tested 2 command: "mosquitto_sub -t “owntracks/#” on 1 screen and “mosquitto_pub -t “owntracks/ben” -m hello” on another, everything worked fine.
On Owntracks app, I chose private MQTT mode, host: 192.168.137.2 (this is my raspberry pi ip address), port:8080, no websocket. Identification: username:pi, password:(my raspberry login password), Device ID: ben, track id: be
No TLS, No parameters
I have one item which is defined as:

Switch  PresenceBen_PhoneMqttHome   "Ben @ Home"   { mqttitude="mymosquitto:owntracks/ben/event:home" }

Please instruct me, @Max_G, you’re my only hope

Hi, i want to start with MQTT and Owntracks on OH2.

I have already working owntracks on my android smartphone and working mosquitto server on my debian-server. I´m on OH2.1 Snapshot release.

But i can´t get any data inside openhab.

Can someone help me to configure my mqtt-binding and items?

Only thing in my mqtt.cfg is this:

mosquitto.url=tcp://localhost:1883

No authentication, no encryption (for testing). On my debian shell i get this output of mqtt-client:


owntracks/mosquitto/note4 {"_type":"location","tid":"e4","acc":20,"batt":21,"conn":"w","doze":false,"lat":xx.1234567,"lon":yy.1234567,"tst":1493879351}

How can i test if i get data inside openhab?

My item for testing is:

String  locationPhone  "Test Raw Data [%s]"   { mqtt="<[mosquitto:owntracks/mosquitto/note4:state:default]" }

I´ve found this example in this thread. But it doesn´t seems to work. I don´t get any values to this item (i´m showing it on my sitempa).

Hi @halloween,

I use println statement(s) during in my rules during development to see if I does what I expect. Maybe the following snippet is of help:

rule PositionPatrik
  when 
    Item mqttPositionPatrikRaw changed
  then
    val String json = (mqttPositionPatrikRaw.state as StringType).toString
       
	// {"_type": "location", "lat": "47.5010314", "lon": "8.3444293",
	//    "tst": "1422616466", "acc": "21.05", "batt": "40"}
	val String type = transform("JSONPATH", "$._type", json)
    println("MQQT: " + json)
	if (type == "location") {
	  val String lat  = transform("JSONPATH", "$.lat", json)
	  val String lon  = transform("JSONPATH", "$.lon", json)
	  val String acc  = transform("JSONPATH", "$.acc", json)
	  val String batt = transform("JSONPATH", "$.batt", json)

with kind regards,
Patrik

I am also trying this but get this error:

[ERROR] [.script.engine.ScriptExecutionThread] - Rule 'MqttPostionParseCraig': Could not initialize class com.jayway.jsonpath.internal.DefaultsImpl

My mqqt works as I get

[vent.ItemStateChangedEvent] - mqttPositionCraigRaw changed from {"_type":"location","tid":"CL","acc":22,"batt":83,"conn":"w","lat":xx.xxxxx,"lon":-yy.yyyyy,"t":"u","tst":1507125675} to {"_type":"location","tid":"CL","acc":26,"batt":74,"conn":"w","lat":xx.xxxxx,"lon":-yy.yyyyyy,"t":"u","tst":1507127788}

I just can’t parse it with JSON. I do have the transformation installed

Hi, did you manage to make it work? I am in the same problem and would need help …

28

Hi Antonio,

what problem do you have exactly? Make sure that you have the JSONPATH transform package installed …

with kind regards,
