## What it is
Pi.Alert is a self-hosted WIFI/LAN intruder detector that scans the local network for connected devices using arp-scan, Pi-hole, and dnsmasq, and alerts on unknown devices, disconnections, and IP changes. It includes a backend scanner with email reporting and a web frontend for managing a device inventory and viewing sessions, events, and presence.

## Use cases
- detect unknown devices joining my wifi network
- get alerted when a device disconnects from my lan
- monitor always-connected devices going offline
- track ip address changes on my home network
- keep an inventory of all devices connected to my network
- integrate network scanning with pi-hole and dnsmasq
- run an intrusion detection system on a raspberry pi

## When to choose
- you run a home or small-office network and want self-hosted device monitoring
- you already use Pi-hole or dnsmasq and want complementary network visibility
- you want email alerts for new or disconnected devices on a Raspberry Pi or Linux box

## When to avoid
- you need enterprise-grade IDS with deep packet inspection or signature detection
- you need a cloud-managed or multi-site network monitoring solution
- your environment is not Linux or lacks access to arp-scan/Pi-hole/dnsmasq data
