How it works

The system continuously scans the network for:

• New devices
• New connections (re-connections)
• Disconnections
• "Always Connected" devices down
• Devices IP changes
• Internet IP address changes

Scan Methods

Up to three scanning methods are used:

• Method 1: arp-scan. The arp-scan system utility is used to search for devices on the network using arp frames.
• Method 2: Pi-hole. This method is optional and complementary to method 1. If the Pi-hole DNS server is active, Pi.Alert examines its activity looking for active devices using DNS that have not been detected by method 1.
• Method 3. dnsmasq. This method is optional and complementary to the previous methods. If the DHCP server dnsmasq is active, Pi.Alert examines the DHCP leases (addresses assigned) to find active devices that were not discovered by the other methods.

Notification Service Support

• Apprise
• Pushsafer
• NTFY
• Webhooks (sample JSON)
• (❗Experimental) Home Assistant (via MQTT (processing ~5s per device, deleting not supported, use MQTT Explorer for now))

Security

There is a configurable login to prevent unauthorized use.

• Set PIALERT_WEB_PROTECTION = True in pialert.conf to enable. The default password is 123456. To change password run /home/pi/pialert/back/pialert-cli
