Domoticz

Hi, i need to change a topic (domoticz/in). The MQTT Server works only a specific topic, for this cause, i cant run correctly the device: "MQTT Client Gateway with LAN interface". I need to change yes o yes, sorry. How i do to change the topics name?
Thanks!!

AFAIK You cant...
You have to use Nodered or something similar to resend topics to domoticz/in

No, i cant use another app or system how Nodered or something similar. Only can continius with my task in my work, if change this topic
Sorry for the insistence...

Hi,

Sorry to say you cannot and you should not change the topic.
The Domoticz interface subscribes to the topic domoticz/in and publishes to the topic domoticz/out.

Everything you want to send to Domoticz you should publish to domoticz/in in a format that domoticz understands.
See: https://www.domoticz.com/wiki/MQTT.

Domoticz publishes messages (payloads) to domoticz/out. By subscribing to domoticz/out (e.g. with a tool, like MQTTfx) you can read these payloads and sort them, do manipulations, and publish new payloads to the topics you want. You receive them in a specific format from Domoticz.
See the example below:

{
"Battery" : 255,
"RSSI" : 12,
"description" : "",
"dtype" : "General",
"id" : "0000044D",
"idx" : 153,
"name" : "Raspberry Pi 1 CPU_Usage",
"nvalue" : 0,
"stype" : "Percentage",
"svalue1" : "7.73",
"unit" : 1
}


The ideal tool to do this is Node-Red, as devros already mentioned.
So changing the topic name (as said: not possible) or even publishing directly to domoticz/in will not help you as the msg.payload requires a specific format.
