Configuring DrvMqttPublisher

[Hennie_Kotze]

Good Day,

I want to use the MQTT publisher driver to publish data to a broker.

I have added a communication line using the driver, but I am struggling with the rest of the configuration. Do you have a short description of the configuration steps perhaps?

Regards,

Hello,
There are 2 ways to publish data via MQTT:
1. Using the DrvMqttPublisher driver. Use this way to publish data of the selected channels.
You should select the MQTT type of communication channel. Add a device, and set up the device’s properties.

2. Using the DrvDsMqtt driver to create an MQTT data source. It’s more handy when you need to publish all data of the specified devices.

Try to configure it intuitively, and publish screenshots if some settings are not clear.

Is there any manual for the DrvMqttPublisher
we want to get modbus data and sen it as JSON using MQTT

[Mikhail]

No, unfortunately. Set up intuitively. Write here in case of issues, providing screenshots.

can we know what are the MQTT Publisher Publish Format parameters
is it posible to send whole table and not line by line
what are the values of @stat
how can i access any channel from javascript

[Mikhail]

MQTT Publisher sends data tag by tag. Payload format is configurable. I suggest to try. It does not require much efforts.
