About
ARP-Scan Device Tracker is a Home Assistant integration that tracks devices on the local network using ARP scanning. It creates a device tracker for each device found, reporting a home or not home state. The scanner is written in pure Python, so no external arp-scan command is needed, though it uses raw sockets that need network permissions. Setup runs through the UI, with the network interface and range detected automatically. Settings cover scan interval, consider-home delay, ARP timeout, optional reverse DNS hostname lookup, include and exclude IP lists, and whether new devices are tracked automatically. For ZeroTier, WireGuard or Tailscale networks, it can probe a given list of IPs instead of scanning the subnet.

ARP-Scan Device Tracker
- Network InterfaceSelect a network interface from the list
- Network Range (CIDR)Network range in CIDR notation (e.g., 192.168.1.0/24). Leave empty to auto-detect.
- Scan IntervalHow often to scan for devices (5-300 seconds)
- Consider HomeHow long to wait before marking a device as not home (10-1800 seconds)
- ARP TimeoutTimeout for each ARP request (0.5-10 seconds)
- Resolve Hostnames (DNS)Look up device hostnames via reverse DNS lookup
- Enable Found DevicesEnable newly found device tracker entities by default. When disabled, new entities are added but disabled in the entity registry.
- Track New DevicesAutomatically create device tracker entities for newly discovered devices. When disabled, only previously known devices are tracked.
- Include IPsOnly track devices with these IP addresses (comma-separated list)
- Exclude IPsSkip tracking devices with these IP addresses (comma-separated list)
- ZeroTier/VPN Hosts (IPs)Probe only these IPs instead of scanning the network (for ZeroTier, WireGuard, Tailscale, etc.)

From the README
A Home Assistant custom integration that tracks devices on your network using ARP (Address Resolution Protocol) scanning. Which works very fast and is very accurate. This integration uses a pure Python implementation - no external arp-scan command required!
