Tutorial ESPEasy / OpenHAB problem

[NietGiftig]

I am having a test setup with Raspi2, TP-link wifi router, ESP8266-12, OpenHAB, Mosquitto and of course ESPEasy

I'm using the router as a dedicated home automation wifi.
It has no Internet connection,just using it as switch

I have connected the Raspi with a wifi stick to the router.
The Ethernet from the raspi goes to my home network so I can manage the raspi also from there.
The serial from the ESP8266-12 is also connected to my work PC
I have connected a laptop to the Home Automation wifi so I can communicate to the ESP8266-12 via the webinterface

I have installed OpenHAB and Mosquitto MQTT on the raspi with the demo site from OpenHAB.

Then I used the EasyESP tutorial for OpenHAB (LED on/off)
I'm using ESPEasy build 20 from Github

I can reach the ESP8266-12 with the webinterface and have it configured for my home automation wifi, I called it "TestESP"
I have managed to let OpenHAB speak to MQTT following the tutorial, I've monitored the MQTT messages to /TestESP/gpio/2 and it is sending 0 and 1 as expected.

The only thing that does not happen is that the LED on gpio 2 responds

Is there somebody out there who has this tutorial working?
Or somebody who has an advice how to trace/tackle the problem?

Hello,

Nice to see that someone is actually trying to use the openhab with ESP Easy. We did a test some time ago and it did work at that time (R16). But maybe later development did break something here.

Do you get this message on serial out when the ESP starts:

Code: Select all

MQTT : Connected to broker

I checked the code, but the debugging part has been commented out. Have to improve this in some newer release. You might be able to enable this yourself for time being. If you navigate to the "controller" tab and find lines 387 & 388, should look like this:

Code: Select all

  //for (byte x = 0; x <= count; x++)
    //Serial.println(topicSplit[x]);

and change it to:

Code: Select all

  for (byte x = 0; x <= count; x++)
    Serial.println(topicSplit[x]);

Upload to ESP and see if it shows the received MQTT topic split into separate lines.

Yes and no, I want to work with OpenHab and Mosquitto.
I think this problem has to do with the interface Mosquitto <> ESP8266

MQTT : Connected to broker

Yes it is there
I have uncommented the lines for the debug print, but no result in the serial terminal.

In the sketch i see that the MQTT port is hardcoded (1883).
I do not think thats correct, it can have another one if configured in Mosquitto, (not in this case).
Maybe that there is a mixup in names/ip's and ports for the use with Domoticz

I have also problems with the AP key / Sta key and the initializing of ESPEasy in espeasy.ino
I cannot get my finger behind this at the moment.
It looks like the login code of the ESP is persistant between new flashes, if true then it's probably by design .
I think that there is a problem in the logins, usernames, passwords, ports.
But that's not for this thread, i will open another one for that (once I can describe the problem.)

I continue the search

Now you have me confused. You do have an ESP buy you're not going to use it with openhab/ESPEasy
Would have been nice... We need more people to help testing/debugging/etc.

In the sketch i see that the MQTT port is hardcoded (1883).

You're right about the hardcoded portnumber. That's a bug, but it should still work if you're using the default port on Mosquitto.
It's fixed it R21.

I've had a chance to boot up the openhab testlab and tested against ESPEasy R20. Still works in my testlab (can blink the blue led on/off), so we haven't broken things since R16. Your unit connects anyway or you would not see the "connected to broker message"

So what's wrong in your environment?

In case of OpenHab we decided to have the ESP listen to all topics address to it's name

Code: Select all

/<espname>/#

If I use the MQTTfx tool, everything I publish on that channel is shown on the serial console of the ESP if I use R21.
R21 is available now on github. Maybe you can use this version, so we know that we're using the same sketch...

This is my serial log:

Code: Select all

INIT : I2C
MQTT : Connected to broker
Subscribed to: /openhabdemo/#
INIT : Boot OK
Boot
0
normal boot
MQTT : Topic /openhabdemo/gpio/2
gpio,2,1

And the led is on...

Sorry, my fault, of course I want to use ESPEasy otherwise I would not be here.

Not good at RTFM
I had called my lovely little ESP8266 E12 "ESPTestboard", because it is sitting in my testboard.
After setting the serial debug to level 4, i did see some lines more in the serial monitor.
(Advice for everybody, set the level high)
That's when I saw the problem, because in the openhabdemo it has a different name, and so a different message topic in Mosquitto.

R21 is available now on github. Maybe you can use this version, so we know that we're using the same sketch...

I have, problem has been solved
Th next one is comming, but not ESPEasy.
When I change the buttonstate in OpenHAB a couple of times quick, mosquitto stops responding for a few seconds.
When I do the same in the Raspi terminal console it keeps working.

Code: Select all

 mosquitto_pub -d -t /ESPTestboard/gpio/2 -m "1" 
 mosquitto_pub -d -t /ESPTestboard/gpio/2 -m "0"
 

But that has nothing to do with ESPEasy

Hi guys. I too have set this demo up today with R78. I am using MQTT.fx to get status updates from the ESP every 60s on the channel /PetesESP8266/# and this works flawlessly. Tonight I wanted to try publishing to turn the internal blue LED on but when I publish this

Code: Select all

/PetesESP8266/gpio/2

, the blue LED turns on (no payload sent) and I cannot turn it off without hitting reset on the board.

The MQTT server is running on my Synology NAS and the ESP can see it.

Am I doing something wrong?

P.S I'm still learning OH2 so wanted to get familiar with MQTT before delving deeper into OH.

[dabe5]

when I publish this

Code: Select all

/PetesESP8266/gpio/2

, the blue LED turns on (no payload sent)

So what do you expect when you send no payload? I wouldn't even expect that it switches on.

Try to send payload 1 for on and payload 0 for off

I have it running for dimming a RGB LED String and it works well. I can see everything in MQTTfx and Mosquitto and OpenHAB is running on my Synology.

[xbmcnut]

@dabe5 Yes, that is why I'm puzzled. When I publish

Code: Select all

/PetesESP8266/gpio/2

without anything else, the internal blue LED turns on. Sending 0 or 1 in the payload makes no difference and I have to reset the board to get the LED to turn off.

[dabe5]

I have no problems to switch the gpio on/off with

Code: Select all

/ESP-OG01/gpio/14

and payload 0 / 1

or

Code: Select all

/ESP-OG01/pwm/14

and payload from 0 to 1000 for dimming the LED

but I never tried with GPIO 2.
I use GPIO 12, 13 and 14

[xbmcnut]

Thanks for the advice. I'll try that tomorrow.

Hi,
something is wrong in R93 or me...
I set gpio15 at ON, 1 or 255 via openhab/mgtt -> it works
but after reboot ESP, gpio15 starts with 0 -> and goes not to ON, 1 or 255.

I would like the same state before reboot...
How can i fix that?
should i set gpio15 as switch?
Thanks
