on the hardware side
I need to design a circuit that can read 2 rfid readers with weigand reading format 26 and 2 ibutton readers (1-wire),
this based on an esp8266 board, I am currently working with the wemos d1 mini pro. The plate (or shield) that must be designed to handle 2 relays, in order to be able to close doors.
on the software side
On esp8266 i need to send the data read from rfid or ibutton to the server (with Python) using MQTT protocol
The server must validate the data and send a response using the same protocol. When the plate receives the message you must validate it and activate a relay
I am ready to work on this project. If you have the hardware ready then I can deliver the code within one day. Please do let me know if you are interested in my bid on chat.
