Pi.Alert
Pi.Alert is a home network monitoring and intruder detection system designed to track connected devices and maintain an active inventory across local area networks. It functions as a network discovery tool, topology mapper, and uptime monitor that alerts administrators when unknown devices connect or known hardware goes offline. The platform provides a central dashboard for visualizing infrastructure links, monitoring website availability, and inspecting SSL certificates through periodic health checks.
The application supports distributed satellite scanning, allowing remote monitoring nodes in isolated network segments to report inventory data back to a central instance via encrypted telemetry routing and token authentication. Device management capabilities include bulk editing, custom metadata profiles, search filtering, and detection of randomized MAC addresses alongside unauthorized DHCP servers. Multi-channel notification services dispatch alerts across email, messaging platforms, push services, and MQTT protocols.
Additional administrative capabilities include command-line utilities for background service configuration, database maintenance, and software updates, complemented by an API for system health inspection and external integrations.
Features
- Home Network Monitors - Discovers connected devices and tracks online status across a home or small office network through a central dashboard.
- SQLite Persistence Engines - Stores device inventories, historical telemetry, and user configurations in a lightweight file-based database for simple local deployment.
- Device Profile Configurations - Stores descriptive metadata such as custom names, owners, types, locations, and groups for every discovered network device to keep inventories organized.
- Network Device Dashboards - Provides a web interface to view historical device data, annotate details, and manage connected network hardware.
- Network Device Discovery - Searches the local network using various router and system utilities to discover connected hosts and log their status.
- Network Topology Mapping - Maps local network infrastructure by connecting endpoints and displaying device links on a central dashboard.
- Self-Hosted Network Discovery Tools - Scans local networks using various probing methods to maintain an active inventory of connected hosts.
- Endpoint Authentication - Secures the web application with login authentication and protects programmatic endpoints using cryptographic keys.
- Network Intruder Scanners - Alerts administrators immediately when unknown devices connect to the local network or when known hardware goes offline.
- Network Intrusion Detection - Sends notifications when unknown devices connect to the network or when known devices lose connection.
- Network Device Monitoring - Discovers active hosts on local area networks using various scanning methods and network hardware integrations.
- Multi-Channel Notification Workflows - Sends alerts about network events through email, messaging platforms, push services, and MQTT protocols.
- Host Offline Notifications - Triggers automated notifications when designated network devices go offline or experience connection drops.
- Virtual Device Representations - Creates virtual representations for IP-less or non-scannable hardware components to visualize complete network topologies.
- Device Management - Performs mass administrative actions on multiple network devices simultaneously using specialized list editors and filtering tools.
- Database Backup and Restore - Creates backups of application databases and configuration files, and restores previous states or exports device inventories to CSV files.
- Randomized MAC Detection - Identifies hardware utilizing randomized MAC addresses and flags them in the active device inventory.
- Distributed Scanning Agents - Deploys remote scanning agents into isolated network segments to monitor separate areas and report findings back to a central instance.
- Device Attribute Management - Modifies attributes for multiple network hosts at once by selecting them in a shared list and applying batch updates.
- Rogue DHCP Server Detection - Identifies unauthorized Dynamic Host Configuration Protocol servers operating on the local network.
- Health Status APIs - Provides an API for inspecting system health, online device lists, and ping results using secure API key authentication.
- Upstream Proxy Relaying - Forwards encrypted monitoring data through an intermediate web server when direct connection to the central instance is restricted.
- Topology Mappers - Visualizes network infrastructure by connecting endpoints and tracking relationships between devices in a dashboard.
- Transmission Encryption - Transmits encrypted network scan results securely to a central monitoring server using encrypted payloads and token authentication.
- Isolated Network Scanning - Deploys remote scanning agents into isolated network segments to report inventory data back to a central instance.
- Service Uptime Monitors - Checks website availability, response times, and SSL certificate changes through periodic HTTP and ICMP health checks.
- Distributed - Deploys remote scanning agents into isolated network segments to report findings back to a central dashboard.
- Telegram Notifications - Dispatches alerts and monitoring updates directly to Telegram chat services using bot integration.
- Remote Power Wake-up - Sends Wake-on-LAN packets, runs manual port scans, and executes network speed tests directly from the management interface.
- Email Notifications - Dispatches automated alert emails when network events or service state changes occur.
- List Search Filters - Narrows down large lists of hosts using search queries and filter buttons while preserving active selections across views.
