Enviro+ MQTT Callback API version 1 is deprecated

Hi,

I had a Pi 4 with the Enviro+ sensor in one of my server rooms pushing data into Mosquitto which was then read by PRTG. This unit as been happily doing it’s job for the last couple of years but the SD card died so I’ve rebuilt it with a new SD card only to find some of the commands contained within the mqtt-all.py example script are now deprecated within the latest version of Pi OS. Please see output below, I wonder if there is someone more adept at Pi OS who can help me get this working again?

Thanks,

Nick
