How to apply a Regex filter to incoming MQTT (version 2) messages?

In the old version of the MQTT binding, when I created items I could apply a regex filter to incoming MQTT messages and ignore those that were not relevant:


I’ve re-done my whole setup with the new MQTT binging using PaperUI. How can I add that filter to ensure that (in this example) non-‘Temperature’ messages are ignored by a particular item?

Cheers to anyone who can help.

This is a tasmota sonoff, correct?
Then you don’t need the regex because the JSONPATH transform pull the value of temperature only out of the json for you
