OK, I think I understand.

Would it be hard to allow mixed format to allow ["dev" + "identifier"] and ["device" + "ids"] mixed combinations? maybe (MQTTAutoDiscover.cpp at line 669):
rootdev = root["device"];
if (root["device"].empty()) rootdev = root["dev"];

if (!rootdev.empty())
{
rootids ...

These are mine unique-id's

0x00158d0004a98668_temperature_zigbee2mqtt
0x00158d0004a98668_humidity_zigbee2mqtt
0x00158d0004a98668_pressure_zigbee2mqtt

There are no unique id's in the above config. That's a first issue... there is no way telling if they belong to each other


By "above" you mean ...

For example when using the below config payloads, it creates one combined sensor.
Maybe you could ask openMQTTGateway to do the same

(have a look at the unique_id)



Thanks for your answer. Do you mean that the config topics should be:

homeassistant/sensor/Nexus-TH-1-117/humidity/config ...

From that I learned that Domoticz tries to combine device attributes when the device name is the same. I guess that in your case Domoticz gets confused since all device attributes have the same device name (eg "mdl":"Nexus-TH","name":"Nexus-TH-1-117"). When battery and signal strength would have ...

Hello,

I read these posts with much interest.

I am using the openMQTTGateway on an ESP32 to monitor a few 433 devices in Domoticz through Mosquitto. It works, but I noticed a small problem: previously I was using and rfxTRX433 usb device and each sensor was combined [ie. a temp + humidity sensor ...

Can you post those config topics?

Thank you for your help. Where do I find these config topics ?

Hello,
I am running Domoticz for a few years and I am very happy. Thanks to the developers and the forum members.

For now, I am using an RFXtrx433 usb to receive information from a few cheap thermometers or door sensors and to control my SOMFY blinds (RTS). I works but my house is quite large and ...

Answer to myself:
it works with "MQTT Client Gateway with LAN interface" and a dummy switch with od configured in Tasmota.

I'd like to have it work with auto discovery if possible, so this topic is not full closed. Any idea?

The server also runs a MQTT server (mosquitto) and Zigbee2MQTT.

In Domoticz I created a new hardware "MQTT Auto Discovery Client Gateway with LAN interface" with Auto Discovery Prefix ...
