I wrote a custom Keypad program using raspberry pi and .NET Core Framework for Raspbian OS. Users have separate pin codes, have start date and end date for validity, and all actions are logged in the database. Connects to hubitat via maker API.
Uses MariaDB/MySQL.. working on webserver using Blazor to see logs and configure users and button settings.
Anyways just thought I'd see what y'all thought.
The car was $50 3D printed, screen in like $10, keypad is $10, would work with raspberry pi zero w for $25 or whatever..
