What does "send to MQTT" do?

I was playing around with some MQTT and tried to find out what the "Sendo to MQTT" option does but to me it looks like it doesn't do anything? Can someone explain?

When you push MQTT button you should get a settings page to set MQTT.
For MQTT settings see the Wiki:

This option allows you to send device values to MQTT, for example, just like the InfluxDB pusher does.
You have to enter your MQTT server paramers first and press 'save'.
Next you select for example a P1 device and say that you want to export the 'usage_current' to MQTT.
Or you push your outside temperature.
Of course, it's only pushed when a value is received/changed

It is also possible to export multiple values of a device (like a P1 meter or a temp+hum)
Code: Select all
{
"delivery_1": 1184073,
"delivery_2": 2783062,
"delivery_current": 0,
"usage_1": 9368981,
"usage_2": 6269705,
"usage_current": 108
}
Code: Select all
{
"barometer": 1010,
"forecast": "Some Clouds",
"humidity": 70,
"humidity_status": "Wet",
"temperature": 13
}

Thanks, a basic wiki page has been created:

It seems a little bit the same when you create a MQTT hardware and empty the Topic In Prefix to disable listening to MQTT. Then use the Setup button of the MQTT Client gateway in menu Setup - Hardware to filter only the devices you want to send the data to the MQTT Topic out.

@waltervl, I'm not quite following you, but this is separate from any hardware device

I know but in the end to get only a limited number of device data being pushed to MQTT there are now 2 options:
- The standard MQTT hardware gateway with only out topic defined and a device filter activated

Domoticz MQTT Push will only push integer value of dummy voltage device with decimal value.
In 2024.4 this function is only pushing the integer value of a Dummy Voltage device:
As viewed from MQTT explorer:
Topic
Code: Select all
Domoticz_Push
329
state = {"voltage":245}
Value of device in Domoticz = 245.78
Is this a bug that needs to be reported or is there some other way to get this working?
P.S. What does the "Link active" switch control in the MQTT Push setup?

Issue was already reported by another user and recently fixed in 2024.7 beta.
