MQTT Broker gateway

[adrianmihai83]

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 :)

[adrianmihai83]

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.

[adrianmihai83]

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:

1. 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
2. motion sensor at MYMQTT/0/2/V_MOTION
3. 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.

@John Could you send me log from MQTTgateway also? (or tcpdump)

I have a next problem:

I connected the serial to MQTT GW:
If I have connected Wiznet, I've got "0;0;3;0;9;check wires",
if i disconnected Wiznet then got "Started!"

@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.

[kihotx]

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 ?

[Damme]

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 Good luck!

[CARSTEN]

@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 out

Any 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?
