I am looking for a person that has made the backend part of a hotel door lock system. A system where the guest gets an RFID key, that opens the door for the room he occupies. I would also need suggestions of suitable locks for the doors. I want to house all lock components, including the reader and mobile access board, inside the door. Unless you have a better idea, the door locks will include electronics; ESP32 with WIFI, RFID/NFC reader, buzzer, batteries, and electromechanics (designed maximize battery life) to enable a solenoid, "Heschen Electroimán solenoide HS-0530B DC6V". A cable will connect the solenoid to the electronics. The server is a Raspberry pi. Raspberry Pi Zero W, Running Node JS. I will supply images of all UI for the server. The server reside inside the wifi network. It has a wifi/NFC reader/writer connected to it. Milestones are; 1. Firmware for ESP32. 2. Server side coding. Server side coding should include a script to install all server side software on an Raspberry pi 3. PCB design. 4. 3D Design of housing for electronics and batteries. It will mount inside the door, in the same way as a hidden lock. Communications in the system should be safe, as safe as possible.
