Hello,

In this case, you will need to create two Data to Server instances with different filtering options. For example, these are the Modbus requests I will use for this example:

So each Data to Server instance should look like so:

An alternative could be to use the Modbus Master request name in the Data to Server template:

{"Timestamp":"%d","%r":"%a"}

And the sent messages will look like so:

[{"Timestamp":"25/09/2023 08:40:29","rssi":"[-49]"}]
[{"Timestamp":"25/09/2023 08:40:29","temp":"[310]"}]

In this case, no filtering will be needed.
Segment count can be set to all, to receive all of the strings in a single MQTT message.
Hope this helps!

Best regards,
