Leak Detector

Version: 1.1.1 | Author: ChitUI Developer | UI: Toolbar (droplet icon)
Dependencies: requests, zeroconf (optional, for mDNS auto-discovery)

Updates

• Multi-module support — each ESP32 is tracked and named independently (e.g. "Saturn Vat", "Mars Vat"), so alerts and notifications always say which printer they're from
• Push notifications now include the module name in the title
• Fixed: alert locations showed the raw ESP32 slug (vat_center) instead of the formatted name from Settings (Vat Center)
• Fixed: Rename/Delete buttons had a hard-to-read transparent background
• Notification module-name brackets now have padding for readability: [Saturn Vat]

ESP32-based resin leak detection system with real-time monitoring and alerts for 3D printer safety. Supports multiple independent modules — install one per printer without them colliding into shared state — and dispatches customizable alerts the moment a leak is detected, attributed to the exact module and sensor location that triggered it.

Features

Multi-Module Management

• One module per physical ESP32, auto-registered the first time it reports in
• Editable name per module (Settings → Modules)
• Independent sensor names/locations/enabled flags per module — nothing shared across devices
• Remove a module from tracking when a device is retired
• Existing single-module setups migrate automatically, preserving your sensor names

Device Integration

• Automatic discovery via mDNS — every ESP32 found gets its own module, not just the first
• Manual configuration via web interface
• WiFi connectivity with OTA updates
• Capacitive touch sensors (ESP32-S3) or analog sensors (ESP32-C3)

Monitoring

• 3 sensor zones per module (Vat Center / Front Edge / Build Plate by default, fully renameable)
• Real-time value display per module
• Alert threshold monitoring with auto-calibration on startup

Alerts

• Visual alerts in the ChitUI toolbar, broken out per module
• Push notifications via Chitu Notify (ntfy.sh), titled with the module name
• Browser push notifications (optional)
• Alert history with timestamps, formatted locations, and module attribution
• Configurable alert cooldown, one-click clearing

Safety

• Optional GPIO relay safety cutoff — shared across all modules, so a leak on any printer can cut power; arm/disarm reason log includes which module triggered it
