MQTT sample setup on ESP8266

[njbuch]

@paul Hi Paul, can you share you code, I am having problems with the Wemos D1 Mini boards, and also would like some inspiration to my code. Thanks!

[Stephan35]

Hello,
I also use ESP8266 (ESP07 & ESP12F & WEMO)

Now i tried to send MQTT with MQTTBOX to see what happened .... arhh nothing

Have you any fully list of MQTT order to easy way write my arduino sample ?

Thanks

Best regards

[Stephan35]

Another thing , Should i have a MQTT Password ?
Because i use MQTT with another gateway (Domoticz) , i would like to keep it in this way.
Thanks.

[jkandasa]

@Stephan35 MQTT password is optional.
Right now MyController gives direct support for ESP devices. you can have a look on https://github.com/mycontroller-org/MyControllerDevice

[Stephan35]

Hello, i send an issue on GitHub,
ESP does not take good AP , take old one. ...

thanks

[jkandasa]

@Stephan35 Hope issue addressed on GitHub

[Stephan35]

Right, Now two other things ...
First i try autodetect MQTT server, but failed .

Now ESP disapear from wifi, so i can't access to ESP .

So, is there any special parameter to set MQTT as autodiscover ?

How can i change ESP parameter, i tried to flash it again, but keep parameter in memory.

thanks

wdt reset

[Stephan35]

Tried this :

#define FACTORY_RESET_PIN 4
#define FACTORY_RESET_PIN_STATE 4
#define FACTORY_RESET_TIME 1000*1 //hold the button 9 seconds

No success , still no AP .

[Stephan35]

Again me ,
Is it possible to test MQTT to mycontroller without ESP ?
Can you give me, please, some MQTT order example to understand what is wrong.
MQTT works fine , made some test with domoticz implemented on the same server.
Thanks.

[jkandasa]

@Stephan35 said:

First i try autodetect MQTT server, but failed .

On MyController server your have to enable mcc.mdns.service.enable=true on mycontroller.properties and stop and start.

#define FACTORY_RESET_PIN 4
#define FACTORY_RESET_PIN_STATE 4
#define FACTORY_RESET_TIME 1000*1 //hold the button 9 seconds

No success , still no AP .

FACTORY_RESET_PIN_STATE should be either 0 or 1. When you press the button, If your pin(FACTORY_RESET_PIN) connects on GND, Then you have to enter 0, otherwise 1.

MC[I]: Sending mDNS query[_mc_mqtt._tcp]...
Skipping compressed pointer

Yes, Sometimes I see this error when we use mDNS enabled on ESP device. This error happens on mDNS library.

[Stephan35]

These lines missing at the end of mycrontroller.properties files , very strange :

mcc.clear.message.queue.on.start=true
mcc.clear.smart.sleep.msg.queue.on.start=true

#========================================================================

MyController mDNS service settings

Enable or disable mDNS service

#========================================================================
mcc.mdns.service.enable=true

Anyway, now ESP is connected to my home wireless , i forced ip of mqtt, because discover does not work correctly, and , i dont see anything with mqtt.

So i decided to fully reinstall mycontroller , to understand where i am wrong .

[Stephan35]

Ok now i installed lasted git version.

Here is screen shot :

Gateway

And arduino usb debug

Esp is configured as mentionned at AP Setting

Now, what next ?

MyController seem to be interesting, but, very hard to get it work ... for me .

Is there somewhere any video ? to explain how it work with example and sample.

Thanks

@Stephan35

You can use your ESP as a node and can fun with your sensors with monitor, reports, and actions...

I am sorry for this. Right now we do not have any videos. I will update a video when I get time. Thank you for your valuable feedback.

[Stephan35]

Thank for your support.

I am very sad : nothing appear in node and sensor.
So i was completly wrong about thinking autodiscover node with MQTT ?
I have to add manually all node and sensors ?
Or my arduino sketch does not contain good command to put it in mycontroller ?

Thanks
Best regards

[Stephan35]

Hello,
Me again .
So now esp seem to send data to mqtt , here is usb logger :

If i correctly understand, ESP_8C0125 connect to broker and subscribe to in_esp/ESP_8c0125
[in_esp/ESP_8C0125/#]

Ok , here is mqtt box sniffer :

etc
etc
etc

MyController does not see anything ... Arrghhh , going to be mad !!!

ID Client have to set to esp_client , but esp client is ESP_8C0125 ?
If changed ti ESP_8C0125, failed connect ...

inverting in_esp and out_esp does not change anything ?

Can you drive me please to get it work .....

Thanks

[jkandasa]

@Stephan35 Sorry for the inconvenience caused.

I see you have selected MySensors as a network type. Which is wrong. You have to select MyController as network type if you use https://github.com/mycontroller-org/MyControllerDevice
I believe you are using built in MQTT broker. What is your MyController local IP? Is it 192.168.0.25?

Here is screenshot from my setup,

• in_esp >> feed data to ESP devices
• out_esp >> data from ESP devices

[Stephan35]

Ok,

What is your MyController local IP? Is it 192.168.0.25?

Yes MyController local IP is 192.168.0.25 (depending of wich router is connected to)

believe you are using built in MQTT broker.

What do you mean by using built in MQTT broker ? this one : First image of this post

Because i have installed mosquitto also , do MyController have it self mqtt broker ?
AND SHOULD IT WORK ALONE ???
I guess my big mistake was there ...

Also , I have so solve install from github to get last version as your .

Thanks again for support

@Stephan35

Yes, MyController has built in broker. No need to install any external brokers like mosquitto. If you want to use an external broker. Kindly disable internal (inbuilt) broker first.

Also , I have so solve install from github to get last version as your .

You can download most recent version from here.

From your post picture, I see you have selected MySensors as a network. Which is wrong. Select MyController as a network type.

[Stephan35]

Here is some good news !!!

First after getting update from github , here is some screen shot from GUI

We can see that MyController is in the list !

Also, Esp send correctly data to mosquitto (which i use by default)

Now , i have to test and learn to send data , like temperature or lighmeter .

Thank you for your time and your support.
