How to command ESPEASY GPIO thru MQTT Mosquitto

[xmenne]

I have a mosquitto broker and Domoticz installed on Pi.
I have a ESPEasy R120 installed on ESP8266 WemosD1 Mini.
All installed recently end of 2019.

I am successfull to have one switch working via Domoticz Http .
http://192.168.1.24/control?cmd=GPIO,15,1 is working fine.

What I want to do is the same thing but thru MQTT.

I have tried several flavor of this configuration without success
ESP03 subscribe Template is >> ESP03/#
Then I Publish on MQTT >> mosquitto_pub -t ESP03/cmd -m gpio,15,1
Therefore I see that on MQTT >> ESP03/cmd gpio,15,1
as expected

The issue is that with several flavor of this command and subscribe template i have no effect on mys ESP and switch.

I have two question for any one who may have a similar configuration :

Where can I see some detailed log in ESPEasy ?
Where am i wrong in the way i write my command ?

You can use the web log or the serial log to see what's going on.

Also the R120 build is quite old, so not all current features may be present.

Hello Thanks,
I uploaded latest version ESP EASY mega.
This is a big change and i will need time to discover the field of possible with this version.
May be i will find a way to avoid HTTP command to adress the GPIO with this Mega version
Need time as this is not my first activity
Thanks again

What I do in Node-RED is to use a MQTT-Out node (running Mosquitto) which is set-up with the IP address of your server
then set-up the topic in the MQTT-Out.

Something like... nodeXX/gpio/14
Where nodeXX is the 'Unit Name' as used in the ESP-Easy Config tab.

14 relates to the GPIO pin, which in this case is D5.

Pin mappings are...
D8 GPIO-15
D7 GPIO-13
D6 GPIO-12
D5 GPIO-14

I have about 40 Wemos D1 Mini devices and each one has a fixed IP address, like 192.168.1.41
So I name the Wemos D1 Mini with 'node41' and stick a label on the botton of the breadboard.
This means it's easy to workout the IP address when I pick-up a breadboard.

The Controller Subscribe setting in ESP-Easy looks like this... %sysname%/#
This means the Wemos named 'node41' will subscribe to... node41/#

To test it out (using Node-RED) you could connect an Inject node to the MQTT-Out node.
Set the Inject node to output a payload of a numeric value - either a 1 or 0 to operate the GPIO pin.

Hope this works for you.

Hello
Many thanks, you open my mind to new path to solution and it works now

What I did for the record

I updated ESP with ESPEasy Mega version
I discovered the new function MQTT Import
I create a new Device Generic MQTT import
Name = Task Name >> RelaisChevret
MQTT Topic1 >> domoticz/out/ESP11_Relai1
andValue Name >> Relai1

When you publish on your Broker
mosquitto_pub -h mqtt.xxxx.net -t domoticz/out/ESP11_Relai1 -m 1

Then your Device Value Relai1 is 1

After that I created Rules (also new for me)
On RelaisChevret#Relai1=1 do
GPIO,12,1
end on

and it works and this close this post I suppose.
I now have to work on Domoticz but it is another story.

Many thanks to you all , this forum is very helpful.
Hope i can help some one one day in return .

The purpose of this MONIT configuration is to have Domoticz restart fully after an electrica shut down of my RASP.
Here we have the config for Web Server monit , config for alerting email and config for Restart Domoticz service

To modify the config go here

sudo nano /etc/monit/monitrc
to check Syntax
sudo monit -t

The purpose of this Script LUA is to activate e relay from Domoticz thru MQTT:

How to rename the file if necessary

mv /home/pi/domoticz/scripts/lua/script_device_chevret_relai1.lua /home/pi/domoticz/scripts/lua/script_device_chevret_relai1_demo.lua

Quand il y a demo dans le nom d'un fichier le script ne l'execute pas

-[[
Intention of this script is to publish defined message using MQTT broker running on a localhost.
The script will trigger only when the status of the defined device is changed.
