Script description

Overview

The WaterLevel app connects to your local smart home setup via MQTT to display current liquid levels—such as rainwater cisterns, water tanks, or pools—through a live-rendered, organic water animation with rising bubbles across the entire LED matrix.

Key Features

  • Dynamic Liquid Animation: Real-time water level visualization (0–100%) with animated rising air bubbles.
  • Silky Smooth Subpixel Bubbles: Continuous vertical subpixel anti-aliasing and gentle horizontal sine-wobble for fluid, realistic bubble motion.
  • Consistent Bubble Frequency: Fixed virtual cycle height ensures bubble frequency and spawn rate stay perfectly steady and calm, even at low water levels.
  • Configurable Auto-Hide: Optional setting to automatically skip and hide the app from the AWTRIX carousel rotation when the water level reaches or exceeds a configurable threshold (e.g. 100% or custom percentage).
  • Live MQTT Integration: Subscribes to any custom MQTT topic, automatically handling both raw numbers and JSON payloads (e.g., {"percent": 75} or {"level": 75}).
  • Clean No-Data State: When waiting for initial sensor data, the display gently rests at a low baseline and shows --% in amber instead of misleading values.
  • Adaptive Text Shadow: Subtle ambient drop-shadow effect rendered behind text and numbers to ensure maximum contrast and legibility against water and bubbles.
  • Display Modes:
    • 52×16 Variant: Supports both high-visibility 10-pixel large bitmap font and standard font with free positioning (left, center, right / top, middle, bottom).
    • 32×8 Variant: Clean, compact standard font permanently centered horizontally and vertically for optimal readability on the 8-pixel matrix.
  • Native Web UI Configuration: Fully configurable via the AWTRIX-NG App settings menu.

Configuration Options
