You didn't add the pull up and pull down resistors. The system does not work stably. If you want, I can set up the circuit for you in Proteus program.

Appreciate the idea of your project. Your code is almost okay, but I have some doubts about it. I also need to cross-check the circuit power. After that, I can conclude the project. I have experience in MQTT and ESP32 very well, so I can definitely solve the problem. I will also provide some upgrade tips. Thank you. Have a great day

I have experience with Arduino and ESP of them, and I will be dedicated to our work. I have good knowledge of Arduino programming and ESP programming.

Hi, there! Thoroughly assess the MQTT connection status at each step of the code execution. Implement debug prints in critical sections to monitor MQTT messages and responses through the Serial Monitor. Verify the proper functioning of the MQTT broker, ensuring it publishes charging details accurately. Inspect the RFID module connections and confirm consistent power supply. Implement debug prints specifically for RFID reading to identify and resolve any intermittent issues. Validate that the ESP8266 subscribes to the correct MQTT topics for seamless communication. Carefully review the code handling incoming MQTT messages, particularly those related to charging details. Review the code responsible for updating the display in the 3rd menu. Ensure that the display is appropriately cleared and updated to reflect accurate charging details. Thank you for considering my proposal. Please feel free to reach out for any further discussion or clarification.

Hello, my name is Mohd and I am a full stack developer with 6+ years of experience in software development. I have the necessary skills and expertise to help you create your charging code for your hotel wallboxes. I understand that the code needs to be fixed so that it's properly working when hotel guests use their room cards to start the charging process. Also, the code has three levels which need to be fixed so that they work properly. Specifically, at level 1 the guest needs to place their room card on the sensor1 of the hotel lock distributor which grants them validity so they can enter level 2 where an mqtt connection is established getting the actual price from the broker on display. Once they accept this charge they can start the charging process by placing the card on sensor2 which is RFC522 module which is able to read the room number of their card. Once the ESP8266 receives approval for the charge from mqtt it sends this information along with the guest's room number to the broker which then updates their display accordingly. From level 3 onward they can see that their charge started as well as its current speed and total amount charged energy.
