Control iDotMatrix BLE pixel displays (16x16, 32x32, 64x64) from
Homey Pro. Show text, clocks, countdowns, scoreboards, images, and
animated GIFs through Flow cards.
What this app does:
* Pairs over Bluetooth Low Energy with any iDotMatrix display
advertising as "IDM-*"
* Capabilities: On/Off, Brightness (5-100%)
* Flow actions:
- Show text (9 animation modes, color, speed)
- Show clock (8 styles, color, date, 12/24h)
- Countdown (start, pause, restart, disable)
- Scoreboard (two 3-digit counters)
- Chronograph (stopwatch)
- Show image from URL (PNG, JPG, BMP, animated GIF)
- Show image from a remote HTTP server on your LAN
(nginx autoindex, Apache, Python http.server, or index.json)
- Show image from the app's local media store
- Probe device capabilities (diagnostics)
* Animated GIFs are automatically resized to the display
resolution while preserving each frame (nearest-neighbor —
perfect for pixel art).
Requirements: Homey Pro. Bluetooth Low Energy is not available on
Homey Bridge / Homey Cloud.
