Looking for quick help with a personal project. I've got a Raspberry Pi Zero W running the Paho MQTT Python client, connected to a RC522 RFID reader using the GPIO pins. I'd like a script which runs in a loop on boot that when it detects an RFID card on the sensor, unsubscribes from all topics then subscribes to a topic linked to the UID of the RFID card. Some of the topics it subscribes to will be integers so I'd also like an example of how I can add a value of 1 to these and publish it back to the broker.
