NetAlertX watches your network for devices: it discovers everything on the LAN with ARP scans, nmap and imports from routers, Pi-hole or DHCP servers, and tracks when devices come and go. It alerts you about new, unknown or missing devices through email, ntfy, Telegram, MQTT, webhooks and more, and ships many plugins for other integrations.
The login password is NETALERTX_PASSWORD in /opt/netalertx_data/.env.
The ARP scan only sees the subnet the container's network interface is on; add more subnets under Settings > ARPSCAN.
Note: This is not in the official repo yet—it's just a dev version! After merging into ProxmoxVE, it will need to be recreated.
