My installation is based on Docker containers, specifically with a version 1.6.15 of mosquitto.
The thing is, with the Home assistant MQTT plugin, you can publish to the MQTT server as you can see in the attached video, and it works.
In the same way, I have configured a KC868-H32B relay to do the tests, and when pressing the relay, it is seen how it publishes the set correctly in the MQTT server but the relay does not change state.
I hope this makes it easier to understand my problem. I'm sure it's stupid but I can't figure it out
It is very curious
