MQTT Broker gateway
-
@Yveaux sure
-
So have I got this right.....?
This will mean that I can build an arduino with an ethernet port and a radio, and this will then plug in to an ethernet port and be what my other ardiuno sensors will connect to, and it will send everything to my Vera?
-
@Homer For Vera you should build http://mysensors.org/build/ethernet_gateway
MQTTGateway is a MQTT broker (server), used for mqttclient like openhab for example.

Ok. I was hoping that this device would enable me to have some of my sensors connected to ethernet so I can power them as well. Rather than sending information over wireless, they would do so via ethernet.
There isn't a way to do as I have described above, right?
-
@Homer I'm sorry but I don't think I really understand your question.
read http://mysensors.org/build/network
Each node (with sensors) talk wireless to A gateway, which then talks to a controller (in your case Vera) this can be via RS232 OR ethernet.If you have something that talks MQTT (like openhab) as a controller, then your choice could be sensors <-> MQTTgateway <-> openhab instead.

I can confirm it's working with UIPEthernet.h and the ENC28J60 module as well. You need to turn off debugging in MyConfig.h to make the code fit.
-
@ToSa Thanks! I havn't had time to get and test that module.

Maybe that was a little too fast - it starts up and starting OpenHAB finds the gateway and connects. When I reset a node it appears that the gateway crashes (OpenHAB reports disconnect) and only a reset of the gateway helps to get it to work again. Problem is it's hard to debug without debugging enabled due to code size
-
@ToSa if possible you could make a tcpdump over the mqqt port and I'll look at it. Also a serial dump from the node would be great

After changing the include from Ethernet.h to UIPEthernet.h the sketch fits into the m328 only with DEBUG (and TCPDUMP) turned off:

Thought you were referring to the "#define TCPDUMP" in MyMQTT.h
I did "sudo tcpdump host 10.0.1.99 -i eth0 -w dump.pcap" on the RPi that is running the OpenHAB runtime (10.0.1.6 is the IP of the RPi with OpenHAB / 10.0.1.99 is the IP of the MQTT gateway) and then did the following:
- power-on MQTT gateway
- start OpenHAB and wait until startup finished
- power-on node with DallasTemperature
The pcap file is attached (not knowing a lot about the protocol it looks like a series of keep-alive messages only and suddenly a connection reset): dump2.pcap
I do not see any messages arriving at OpenHAB... looking at the debug output from the node it appears that the "find parent" message is correctly handled by the gateway but the "node ID request" is not.

@ToSa Thats odd. Everything looks good...(almost, there are some excess of trailing 0x00 but shouldn't matter, but I'll look at that anyways..)
Can you compile with myconfig debug enabled, but define tcpdump disabled? or is it too big that way too?
-
I'm currently busy implementing an mqtt client plugin, and i'm going to use mysensors for it's first predefined implementation so i have a couple of questions
I took a look at the api page and saw this in the mqtt documentation:
[MQTT_BROKER_PREFIX]/[NodeID]/[SensorID]/V_[SensorType]Does this means as example:
MyMQTT/[0-255]/[0-255]/[STRING]/[VALUE]OR this?
MyMQTT/[0-255]/[0-255]/[0-endvarindex]/[VALUE]- Are variable types defined by their index used or by name?
- Also it states it keeps track of node id's how are these reported by the broker, should the controller still hand out free id's?
[EDIT]
I currently do not have the hardware present to at least set it up to test and look at what exactly is happening.
[/EDIT]

@John MyMQTT/[0-255]/[0-255]/[STRING]/[VALUE]
MQTT.cpp :
sprintf(&buffer[buffsize],"/%i/%i/V_%s", msg.sender, msg.sensor, getType(convBuf, &vType[msg.type]));note V_%s -> MyMQTT/[0-255]/[0-255]/V_[STRING]/[VALUE]

@Damme
Clear!And how about the internal messages? Are these somewhat compatible with the Serial API? Like this one now has a "I_GATEWAY_READY" internal var, this one complies then with the "Started!\n" message?
Also about the presentation (if the node does it), are these also passed through?
I know it's a bit question banging... But i just want to do it right.
-
@John No worries!
Presentation is On Todo.. Or Rather To think About list is presentation . I dont do anything with that as it is (Just ignores it). I havn't had any good idea for that yet.Internal is nothing more or less, it connects and set a variable that it is connected.
But sure, there could be transport for internal messages also.
I do have an experimental version there I can send internal messages to reboot node, reboot gateway and set clear read eeprom values. (over mqtt-protocol) but this s not finnished yet.. Ideas are welcome!
-
@John About Presentation ; My idea was that next version of the variable system I will either store some bytes in the MQTT gateway about what S_types to V_types, or hopefully the next protocol contains both those so the GW doesnt have to remember. And then add an extra directory to the MQTT path ( MyMQTT/[0-255]/[0-255]/S_[STRING]/V_[STRING]/[VALUE]
-
I think maybe it depends on the next protocol implementation. Personally i wouldn't mind if the full path mapping was /[0-255]/[0-255]/etc.. to keep (prog)mem print smaller (use the V_ and S_ array index values). It could leave space for more specific things or some extra gateway specific functions.
it would be nice if the mqtt gateway output was "cloned" to the serial output. Controllers should/could be able to map the S_ and V_ types internally. I'm not aware of the openhab config if that would allow this, or that such a setup would require a lot of coding at openhab side.
[EDIT]
It would be more difficult to read though if a path would only exist of numbers. But could also introduce easier maintainability in your library because you wouldn't have to keep track on type namings.
[/EDIT].
-
@John That was my first aproach, and I might set a define configuration to choose if the MQTT gateway should translate or not. As you say, the footprint would be much smaller.
Might be next version of the MQTT, slectable address layout
-
@Damme
That would be really coolIt would be nice though if there was a way to identify node id's with AUTO turned on. Maybe i'm missing something or do you have to know up front with auto enabled which node id is going to be assigned?
I'm just asking this because of identifying new/existing nodes in the network. Is it the V_SKETCH_NAME i can refer to?
And i hope some last questions protocol specific:
- Version compatibility is 3.1?
- All session are clean by default?
-
@John upon node startup it translates gw.sendSketchInfo("Battery Meter", "1.0"); into MyMQTT/20/255/V_SKETCH_NAME and version
so you could have a list as in my first post and it would get filled up with all your sketch names
@John ; Yes and I hope so
(I might have missed some stuff, I do not take regard of QOS etc)
if its not working,, I'll try to fix it
-
@Damme
Thanks for all the info. It becomes more clear now, All nodes users add are persistent anyway.
-
@ToSa I'll update mqtt later with option to not translate V_TYPE into name string but to keep it as a byte, that would save a lot of memory and might solve problem you have. I'll keep you posted
-
As I understand it:
The packet on the left would be from the node, the packet on the right would be to the node. Besides swapping sender and destination, the difference is that in 1.4 the gateway does not have the information to binary encode the value, so it sends the value as a string (payload type 0).
EDIT: added alternate MQTT respresentation of V_code as numeric
-
@Zeph but soon there will be a choise to translate v_ to text string or keep it as a byte value
-
At first, I thought MQTT would be a great extension to the functionality, in particular because it might systematize the idea of routing messages to more than one destination - eg: to both a HA controller and to a cloud storage service.
So I saw these possible advantages of MQTT:
- Route to multiple destinations, dynamically updated
- Subscription wildcards to filter for desired subsets
- Possibly easier to build plug-ins for some HA controllers
As I look deeper into it, I'm coming to wonder about that.
- There are lighter weight ways to send to more than one destination
- Does subscription wildcarding meet the filtering needs well (below)?
- Is it easier or not?
I'm wondering what subscription wildcards really get used - how valuable is the type of filtering functionality offered by MQTT for our purposes? The meaingful patterns I would imagine are:
- everything
- everything from one node
- everything from one child of one node
- everything of type V_RAIN from one child of one node (ie: one variable)
- everything of type V_RAIN from anywhere
Are any of these (or other options) in use except "everything"? Do you anticipate that they will be?
Just as "route to multiple destinations" could be lighter, filtering could be done differently as well. For example, suppose you wanted to receive all report of inside temperature (7 sensors in your network) or humidity (5 sensors), but not outside temp or humidity and not other v codes. That might take 12 subscriptions - and they would have to be manually set up, or make use of manually entered metadata tables in the controller plug-in (eg: the plug-in might be configured to know which nodes had temp and/or humidity, and which ones were considered "inside", if it was written to handled that).
I could imagine that even if the subscription filtering wasn't highly useful, MQTT might make it easier to create plug-ins for some HA controllers, than using semicolon separated values (serial text format). Is that the case?
I'm very open to hearing other advantages of MQTT, I'm not against it, just trying to understand the benefits vs cost aspect better.
-
The other extension that occurs to me, in the gateway-as-transparent-switch model, is that if we ever wanted to encode binary values OTA from the gateway to the node, the plug-in would have to tell the gateway which payload_type to use. In the Semicolon Separted Values format, that could be another parameter, eg:
<node id>;<child id>;<command>;<ack>;<v_code>;<payload_type>;<value>Or it could be added to one of the other fields with a comma sub-delimiter, etc.
How would a controller plug in tell the MQTT gateway to use payload type P_UNIT16 to send to node 7?
I'm thinking that it would be done in the value string, rather than encoded into the topic. So maybe the value string goes from "321" to "4,321" or something like that.

@Damme
What happens if a node does not receive it's address when it requests one (because of failed send). It is not registered within the broker?

I could not follow the discussions the last few days - will definitely have a look over the weekend and let you know if that worked. Thanks!
-
@Damme
When the MQTT gateway prints information about itself like "started", is this done with node id 0 or 255?
-
@John 'started' is only a internal log message, I've changed how that part works.
I've also fixed a couple of bugs and will test the changes tomorrow before I publish them.
New functionallity there user can choose of MQTT should translate ID to V_TYPE or not too.
-
@Damme
Ok, my plugin will then just try to reconnect.Ok, i will check that then probably the day after tomorrow, i will make my code take no translation as first and if not found try the naming (internally), because the server takes over the semantics anyway because it also is going to include a MQTT broker service.
Currently the MQTT implementation is being tested with an end user. Maybe he will help test the new possibility without V_TYPE translation when your changes are implemented.
-
@Damme
When does exactly the messages like "MyMQTT/[NODEID]/255/V_SKETCH_NAME" and/or "MyMQTT/[NODEID]/255/V_SKETCH_VERSION" appear? is this only when an address is assigned or always when a node is started?
-
@John then node is started, There was a bug not processing that message which is fixed now.
hasn't been pulled to official yet but can be found at https://github.com/Damme/MQTTGateway/commit/f10843f5efd9c37900624fe57275be11c69e3942

@Damme
Thnx, was struggling with this with a user. Will need to wait for the next release :).

@Damme when will the new release be available?

Dear colleagues,
I have been using OpenHAB for a couple of days now, everything is going the right way, I've been using it with mosquitto broker for Windows, everything is solid, working well an fast. Decided to go a step further and use the MQTT Gateway presented here.
I've made a MQTT Gateway but get the "Not connected to broker" message from OpenHAB. First of all, the Gateway is an arduino uno with a w5100 shield on top in which I inserted the RF module (NRF24L01). Configured my ip in the gateway sketch (192.168.1.11) and uploaded to the arduino.
The first test was to connect with a phone (using MQTT from Playstore - used it many times before) and with a PC (using WMQTT Utility - used it many times before) and things don't look that promising, the problem beeing that client somethimes disconnects, and I cannot receive the message published in a topic (topic that I am subscribed to on the phone, pc and tablet using MQTT clients). I somethimes get the message in the serial monitor of the arduino, somethimes not.
Configured openhab.cfg to use the mqtt broker at 192.168.1.11 (before I was using mosquitto on pc 192.168.1.10 and working without problems) and everythime I change state of something in the dashboard of openhab I get this Broker Connection not Started even if after starting openhab I get serial output from arduino for some time, after this everything drops. Here is the serial output:serial_output.txt
Last two entries are: I opened the MQTT client on my phone, connected to MQTT Gateway and subscribed to topic home/# and the last one is me publishing from the phone to topic home/test the message "test message". None of the messages come back to the clients on the phone, tablet, pc, all of them subscribed to home/#
And here is the output from openhab: openhab_output.txt Ignore the samsung connect stuff, I have pull it off the network, i have managed to get it working well.
Best regards,
Adrian
-
@adrianmihai83 "home/openHAB/out/Temperature_GF_Corridor/state" is probobly long string, 47 chars. I have not investigated exacly how long it can be but keep it short. And the adress layout is also wrong, is should be something like MyMQTT/21/1/V_LIGHT . MQTTGateway is not compatible with the mosquitto broker you're using.
-
@Damme , your instructions were highly appreciated, got it working the first time. I will start creating the network now, I guess that everything will be ok. Will follow this forum for info and knowledge.
Now I will migrate openHAB to Rasberry Pi and add all the sensors one by one, there are a few.
A question though: I am using the humidity sketch and get MyMQTT/0/1/V_TEMP and MyMQTT/0/0/V_HUM reading fine but I cannot get sketch name... I don't know what I am doing wrong... Read above and I guess I have to wait for new version?
Thank you.
Adrian
Edit: Read more about Rasbery Pi capabilities regarding openHAB and I think I will use a cubietruck... Does anybody use one, cubieboard 2 or cubietruck?
-
@adrianmihai83 Sketch-name was a bug that I fixed in development branch, thought @hek updated master branch also. I can post the fix later on in here.
-
Maybe a dumb question but I don't figure things, here is my problem:
Uploaded the relay sketch to the same arduino that I used for humidity/temperature node (I don't know if this is relevant, the network has only one node, this one). Modified the pin that the relay is connected to: #define RELAY_1 4.
I am using the MQTT Gateway openHAB and cannot activate the relay...
Serial output of relay sketch is:
repeater started, id 0
send: 0-0-0-0 s=255,c=0,t=18,pt=0,l=3,st=ok:1.4
send: 0-0-0-0 s=255,c=3,t=6,pt=1,l=1,st=ok:0

send: 0-0-0-0 s=1,c=0,t=3,pt=0,l=3,st=ok:1.4Serial output of gateway is:

What am I doing wrong?
Thank you!
-
If I run the MQTTGateway my temperature shows in fahrenheit when I run the same nodes on a SerialGateway it is showing Celsius why will this be the case?
-
Downloaded from https://github.com/Damme/MQTTGateway latest MQTT Gateway (the one that responds on serial with "Ok!" not "Started!", with the modifications to MySensors.cpp) but no difference, still no sketch name and with the above settings, openHAB cannot control the relay sensor...
I used the same arduino that is working with Temp_Humidity sensor so the setup is good, the relay pins are specified in the sketch. I used the Clean_Eeprom_Config before uploading, I even used other Arduino Uno, no diffrerence, still cannot control the relay sensor from openHAB.
Anyone has a clue, a hint or something? The serial output from both the sensor and the gateway, together with openHAB configuration are two posts up.
Edit: 3 hours later and managed to make many of the sensors (Door, Distance, Dust, Gas, Humidity, Light, Motion) everyone working in conjunction with MQTT Gateway and openHAB except the Relay one...
Any help is appreciated.
Regards,
Adrian
-
Callback for incomming messages does not occur so I guess that the message does not get to the relay sensor. Is there someone that is using this with MQTT Gateway and openHAB?
-
@adrianmihai83 I was testing this today and it was working with the MQTTGateway. Here is my config file same as above:
Switch node2_sw2 "Study Lights" (node2,all) { mqtt=">[mysensor:MyMQTT/2/1/V_LIGHT:command:ON:1],>[mysensor:MyMQTT/2/1/V_LIGHT:command:OFF:0],<[mysensor:MyMQTT/2/1/V_LIGHT:command:MAP(1on0off.map)]" }
Here is the info from the serial port monitor.
-
Will test it tomorrow morning and come back with result, what i see is exactly the same configuration, the only difference is that your's is on the 3'rd node and mine on 1'st node. Anyway, will see.
Thank you for your answer.
I am still waiting for my other NRF24L01 ( I ordered 30 pcs), they will arive this week. Maybe there is a problem running the sketch on node one, id 0. Tomorrow I will go and buy 2 of the NRF24 from a store even if they are 4 times more expensive, this not working is killing me
-
Why is the broker offering me the same id for all of the sensors? I start the first one, broker offers me id 0, without disconnecting it I connect the second sensor and the gateway offers me same id, id=0.
I have cleared eeprom to both of them and see the requesting id first time i power them up, but still same id for both...
Edit 1:
Defined static ID and the relay works, didn't modify anything, just static ID 2 to the relay...
Edit 2:
Just tested with ID 0, 1 and 2 and I can confirm that the relay does NOT work with ID 0, it's almost a week now and I have tried everything and the answer was as simple as this: does not work with ID 0.
-
By ID do you mean node ID? If so, the gateway has node ID 0, so I'm not surprised if it's not good for other nodes.
But you may be talking about a child ID or something else.
-
Yes, I am talking about node ID, but what I can tell you is that until two days ago I didn't assigned node ID manual and I didn't have 3 NRF's to test with gateway + 2 nodes. Only when I got other RF's and made a couple of sensors saw that the gateway is assigning node ID 0 to all of the sensors, and all sensors worked, for example:
- temp humidity node had Node ID 0 and Child 0 and 1, and from openHAB I could use them at MYMQTT/0/0/V_HUM and MYMQTT/0/1/V_TEMP
- motion sensor at MYMQTT/0/2/V_MOTION
- and do on, other 2 sensors, all I had to take care is that all of them had distinct Child ID
Only when I got other NRF's and could make sensors and use them in paralel saw that the gateway is offering NODE ID 0 to all of my sensors, I don't know why, checked MYMQTT.h and it was set to auto assign Node ID, even in the statemant gateway.begin() assumes that the gateway should auto assign Node ID, and gw.begin(incomingMessage, AUTO, true) states it clear that relay sensor should get Node ID from the gateway.
All I did is manual assigned nodes for every one and workking like a charm. I simply like it this way, it let's more control, it's simply more "my way".
Now I want to combine some of the sensors and use a Mega2560 for this, hoping for a nice outcome.

@Damme
You can forget about my posts, after some quite intensive debugging i found out there was an ugly inconsistent race condition going on in my app. Issue is gone now.
-
Could anyone help me with running MQTTGateway with enc28j60 ethernet module? Should a gateway respond to ping? Openhab says 'no route to host'. Should i change anything else than Ethernet.h to UIPEthernet.h in source code ?
-
I just wanted to say hello again to everyone. I had to disappear for a while. Just had too much for my brain to handle. So all my automation project were on halt but will be continued again.
I know there are lot of bugs in this GW and I will hopefullt start developing soon again. Just write your experience you had so far and I'll try to keep up
//Damme

@Damme Good luck!

@Damme I tried today the mysensor 1.4.1 library, uploaded with Arduino 1.5.8 to UNO with Ethernet Shield (W5100) and an NRF24L01+pa+lna. Compilation and upload worked fine.
I can ping the IP address defined in the MQTTGateway.ino sketch.
I maintained on my RPI the openhab.cfg file with the url and port number from the gateway.
When starting the openhab it shows:
... - MQTT Service initialization completed.
... - Starting MQTT broker connection 'mysensor'.Then a couple of message later:
...Mqtt Exception
Caused by: java.net.SocketTimeoutException: connect timed outAny suggestion what I could look at.
I also tried to work with the development library of Mysensors but did not get very far with that. My ultimate goal is to something like a moteino with the RFM69HW radio module in connection with either openhab or pidome.
I have a quite a bit of hardware lying around here so I am happy to do any testing if somebody gives me some guidance.
Thanks.

Thanks for the mqtt broker. Just a tip to people who might fall in to the same pit as I:
The mqtt broker gateway doesn't distribute node ids unless you're connected to it using a mqtt client. I.e. if you did what I did, installed the gateway and wanted to test that the sensors found the gateway and was distributing the code then it doesn't work until you've connected to it. I had to go through the source code to figure it out.
If you don't have openhab or simply want to test, this is what I did on my raspberry (but should work similarly on others)
// install mosquitto client
sudo apt-get install mosquitto-clients// Start the client, replace the 10.0.0.200 with your ip. The port will default to 1883
mosquitto_sub -h 10.0.0.200 -d -t hello/world -v
You should be able to see messages:
Received PUBLISH (d0, q0, r0, m0, 'MyMQTT/20/0/V_LIGHT_LEVEL', ... (2 bytes))

Hi All
Just a simple question:
Are there any limitation in how many MQTT connections/sessions the MQTT Gateway can handle?
If so, can this be changed?
-
Hello. I am new to Mysensors, openhab and mosquitto.. I have a working knowledge of arduino and nrf24l01, and currently am running a wireless(nrf) twitter controlled heating scheduler, and am sending multiple temp (ds18b20) sensors to Xively feed.
I am really hooked on the idea of mqtt and openhab, and i thought that mysensors seemed like a good solution for implementing that idea.
My progress so far is to install the DallasTemperatureSensor by MySensors node to one nano, and the ethernet gateway sketc as a first step, and now i have installed the mqttgateway again from the build page, and i have a working install of mosquitto and openhab on a rasp pi b+.
I am just having difficulty getting it all stuck together. I have created the sitemap items and transform files as above and can access the openhab sitemap for the above configuration. i just don't know if i need to configure other items? how can i test each step? and can i use mosquitto with the setup that i have outlined. There seems to be conflicting info about what can and cannot be done with mosquitto and mysensors.
1 do i need to modify the sketch of the temp node? i have some output from the serial that suggests that it is communicating with the gateway.
2 do i need to modify the gateway with info of the mosquitto server?
3 what can i do to test each step of the transit from temp sensor to openhab?Thanks for any and all responses.
-
Hello!
I've downloaded the 1.4.1 version of the library and tested it via OpenHab.
I'm still not getting the sketch_name correctly via MQTT and Openhab. Is it still an open bug?Thanks!
Simon
-
Hi Simon,
I had the same problem
I tried several time clean Eeprom and flash sketch again but with no results
Only after cleaning of Eeprom with the following scratch my sensor is starting work correctly
I recommend to try it:
Clearing EEPROMIgor
-
@mwhansen Hi, I am also struggling with this, seems it can only handle one connection now which makes it extremely hard to debug or check node ids
-
@Gambituk To connect to a external MQTT server (mosquitto) use this MQTT gateway version:
http://forum.mysensors.org/topic/524/mqtt-client-gateway/
-
Thanks @celonunes I eventually found that version of gateway via somebody else. i have another post with some issues i found with that version. http://forum.mysensors.org/topic/921/strange-value-being-sent-from-controller-using-mixed-temp-relay-node it's not really resolved, but i have some kind of workaround.
-
@mwhansen @alexeinz The MQTT gateway can handle up to four simultaneous socket connections, this is the limit of Arduino ethernet shield (Wiznet W5100).
The problem is that openhab don't get along with the way the gateway handles multiple client packages. I will send a fix for this problem in the next few days.
-
@celonunes actually, i figured a way around it using mosquitto bridge
that way its much more robust too, so I am good
can post my conf if anyone interested.
-
Those are the most recent changes to MQTT gateway:
- Fixed node id distribution by the gateway (reported by @viking)
- Fixed the problem with openhab and multiple MQTT clients
- Fixed the appearance of garbage in messages sent from MQTT to a node
-
I can't change on-off manually for button with relay sketch, if i try, connection is lost, switching from screen never works again until restart everything.

**My main problem is losing connections with nodes. I also tried serial binding and same result.
**
Mysensors+Openhab useless with mqtt and also serial binding
-
@C.r.a.z.y. Could you send the serial output from the gateway? And a more complete log from openhab showing errors?
-
@C.r.a.z.y. said:
I can't change on-off manually for button with relay sketch, if i try, connection is lost, switching from screen never works again until restart everything.
Are you sure it isn't a powering issue of the "button-node" where radio shuts down when you press the button? Are you controlling a physical relay?
-
@celonunes You can find MQTT and serial logs in the zip files openhab 1.6.2 and 1.7.0 logs-1.7.0.zip logs-1.6.2.zip
@hek My nodes are working perfect when i only plug serial usb to any usb socket of a computer-printer-usb hub even a mobile phone charger
they are good without server/controller
-
@hek My relay powered from nano icp headers maybe this makes trouble for wifi , i will change this and give update.
My button is not normal button , its an ir distance sensor which trigers the relay.
-
I can't seem to get openhab to communicate with my MQTT gateway. I can connect to the gateway with the MyMQTT Android app and I receive messages from my light sensor node including the sketch name and light level. I can ping my gateway without issue as well.
However, OpenHab never seems like it notices the gateway. No data in the sketch name or node result. I've used the sitemap, items, and config files as described above and I've also customized them to match my sensor node more specifically. Both without success. The only change I've made is my sensor node is defined as node ID 20 within it's sketch.
When using start_Debug.bat what should I see in the command line window to indicate OpenHab even sees or connects to the gateway. I see no indication that it attempts to connect to the IP address of my gateway.
Thanks
-
Maybe if you can share your items, sitemap, and rules if any.
-
-
can you also please paste a sample of what you see in myMQTT or screenshot maybe? or it can be easier to copy and paste from a terminal window? are you using raspberry pi or something else?
-
@hooraysimpsons unplug the power and restart your modem, check your dhcp menu if it has ip for Ardiuno.
Check your mqtt from serial monitor, you must see "gateway started..."
-
mosquitto_sub -h localhost -v -t '#'
This is what i use to see what is happening on mqtt broker, i am using a raspberry pi and mosquitto installed on the same pi. you can also swap localhost for ip address ie 192.168.0.5 etc
-
@C.r.a.z.y. it sounds like he is getting as far as the mqtt broker, so the gateway must be working. ?
-
Crazy- I was thinking my network connection as a source of the problem. On my router homepage the gateway does not show up as being given an IP. However, the MyMQTT Android App sees the gateway without issue so the routing across my network from phone to gateway is successful. I have attached a screenshot of the MyMQTT andoird app output.
I am trying to run OpenHab on a windows PC. I don't have mosquitto running at all. My understanding is that it is not required.
-
Group all
Group node1 (all)
Group node2 (all)
Group sketch (all)Number node1_light "Light Level" (node1,all) {mqtt="<[mysensor:MyMQTT/20/0/V_LIGHT_LEVEL:state:default]"}Try changing the first line of items like this above.. and in sitemap change node1_temp to node1_light
Also see if activating any of the switches in openhab publishes to myMQTT ?
-
Restarting the modem and checking wires of arduino solved my problem before.
I am sure mqtt have to be in dhcp list.
-
I have restarted my router with no effect. The gateway still does not show up as an active client (using DDWRT) but I still have a connection from phone to gateway.
Added the above line. I've used one before like it but went back to what was given at the beggining of this thread to start anew. I also tried with the following edits
"Light Level"
"Light Level [%s]"
"Light Level [%.1f]"None of which make a difference. The reason I think OpenHab doesn't even see the gateway is because nothing shows up in sketch name either which should work even if the above line was incorrect.
I have done the testing with the Android App turned off as well since I know OpenHab had some issues earlier if other clients were accessing the gateway.
I still see no reference to my gateway's IP in any of the OpenHab output/logs. So I'm not sure it is even trying.
The only error message in my openhab log is:
11:23:46.951 [ERROR] [sphere.cpr.AtmosphereFramework:2215 ] -I tried clearing the EEPROM in the gateway. I changed it's Mac address and removed the DHCP lease for it from my router. Still no evidence of the gateway on my router status page but also still able to connect to it with my phone.
Another update:
I installed Mosquitto and I see the light sensor level using mosquitto_sub -h 192.168.1.134 -t MyMQTT
-
@hooraysimpsons Your gateway seems to be working fine. Do you see something like this on your openhab logs?
2015-02-27 17:48:06.349 [INFO ] [.io.transport.mqtt.MqttService] - MQTT Service initialization completed. 2015-02-27 17:48:06.350 [INFO ] [o.i.t.m.i.MqttBrokerConnection] - Starting MQTT broker connection 'mysensor'
-
@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.

Just want to make sure I'm understanding this correctly since I feel the MQTT terminology is new to me.
The MQTT Broker is the MQTT server so if I wanted to use this with openhab on a pi I would just need the MQTT plugin and then point it to the IP of the gateway?
I have the ethernet module ordered so I can't test myself yet.
-
@C.r.a.z.y. You are using the raspberry serial port to connect the openhab with the arduino and the arduino is running the SerialGateway sketch, is that right?
-
@Chaotic said:

That's right.

*1 -> NOTE: Keep first byte at x2, x6, xA or xE (replace x with any hex value) for using Local Ranges.
#define TCP_PORT 1883 // Set your MQTT Broker Listening port. IPAddress TCP_IP ( 192, 168, 1, 197 ); // Configure your static ip-address here uint8_t TCP_MAC[] = { 0x02, 0xDE, 0xAD, 0x00, 0x00, 0x42 }; // Mac-address - You should change this! see note *2 above!

@msebbe Which library your are using for the ENC28J60? The UIPEthernet has some examples you could try to test if your module is working.

Just wanted to say I was able to get this working.Also found a nice little MQTT utility that makes it easy to see the messages being sent from the broker/openhab.
I'm sure I'll have more questions but most of my hardware is still on a boat from china so will be a little while till I discover them.
