pucherot/Pi.Alert — reverse-engineered prompt

Build me a Raspberry Pi app that watches my home WiFi and LAN and tells me when something new connects. I want it to keep a device list with names, MAC addresses, IPs, favorite devices, and notes, then show a simple web dashboard where I can see who is online, past sessions, connection events, presence history, IP changes, and devices that disappeared.

It should scan the local network regularly, use Pi hole or dnsmasq data if they exist, and save everything in a small local database. If an unknown device appears, or if a device I marked as always connected goes offline, send me an email alert with the details.

Please make it easy to install and run on a normal Linux Raspberry Pi, with a clean admin style interface and basic settings for scan timing, email, and device management. Look up current docs online if you need to.
