Python RC522 read and Paho MQTT subscribe loop

$25-50 AUD / hour

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.

pretty straight forward task, shouldnt take more than 4 to 6 hours from start to finish from making the program to setting it up so that it starts automatically on boot, i can either make the program and help you set it up or make a custom image that you can directly burn to the pi's sd card. along with the program that will be able to publish data to a broker based on the card with values also, feel free to check my profile for past projects and text me for more information

Hello, I see you need a python script running on boot. You can do this using systemd daemon. I can help you write the python script so it can be run as systemd daemon. Regards
