MQTT, Not domoticz not sending

[goblin]

hello all,
I need some help with MQTT.
I have added a new ESP32 (espeasy ) with 4 inputs and 7 outputs to control light based on PIR's.
The inputs from the ESP are received in Domoticz but switching a lamp does not work,
I have tried to find it with MQTT Explorer but see only the working messages.
Changing pin on ESP will result in a change in Domoticz but pressing a button in Domoticz will not result in change on the ESP output.
I am using about 15 ESP8266/32 and 5 x sonoffs. and they all work but it seems i cannot add one (output)
I might have forgot a setting somewhere but can't find it.

version 2047.7

thanks

Are you sure you used MQTT for the ESP which is working toward domoticz? Could it be you are using HTTP JSON API calls instead?

[goblin]

most of the esp8266 are working with mqtt.
the strange thing is that it only works one way

[jvdz]

So did you check the ESPeasy settings on the ESP with the issue, as it is you that needs to configure the domoticz host and protocol to use?

Did you use a device Domoticz MQTT Helper? That type of device can act on the MQTT messages on /domoticz/out.
I think this is the most easy way to implement this. As an alternative you can use Generic - MQTT import.

[goblin]

yes Wim. i am using MQTT helper.
checked all settings multiple times and compared with working units.
What i don't understand is if the settings are incorrect then why does it work from esp to domotica but not from domoticz to esp.
it must be a Domoticz setting because i don't see the message in MQTT explorer if i send something fro domoticz to esp and see a message if i send something from esp to domoticz.
thanks

Hello @goblin,

You wrote:

Sorry, but this header is complete unclear, at least for me.

Can you answer a few questions?

From your ESP32/8266 devices you send the data with MQTT?
Can you see this data in MQTT Explorer?
Did you create virtual switches in Domoticz?
If so, can you control these switches by your MQTT command from the ESP?
If so, can you operate these switches in Domoticz and do you see a result in MQTT Explorer at the topic "domoticz/out"?

it must be a Domoticz setting because i don't see the message in MQTT explorer if i send something fro domoticz to esp and see a message if i send something from esp to domoticz.

Which message do you expect to see?
How do you send it? Operating the virtual switch? Or is it the MQTT input, that should do it?

If it is that last one, you might want to look at viewtopic.php?t=37052&hilit=mqtt+loop

hello all
found the problem.
you need to select setup in "hardware" MQTT client gateway with lan interface"
then select the needed devices and save.
i cannot remember doing this in previous versions.
but never to old to learn.

thanks

Firewizard,
i am using "mqtt explorer" to verify MQTT messages between devices and i can see other MQTT messages from other devices in "mqtt explorer".
i could see in "mqtt explorer" messages send by the ESP but not send from Domoticz.

your questions
yes
yes
yes
yes
no

all is working now due to the changes i have made in the "hardware, mqtt, setup"

regards
