  LedGrab v0.4.0 Stable

  alexei.dolgolyov released this 2026-04-21 19:41:40 +03:00 | 181 commits to master since this release

  v0.4.0 (2026-04-21)

  This release introduces a full Android TV app that embeds the Python server via Chaquopy, with boot-time autostart, root-based screen capture, and a watchdog. New device support includes BLE LED controllers (SP110E, Triones, Zengge, Govee), Android USB-serial Adalight/AmbiLED controllers, and a Group device type for combining multiple devices. Metrics now include battery and thermal-zone readings with a dashboard temperature chart. Devices get a new per-provider typed configuration model, and the project has been renamed from led-grab to LedGrab with the Home Assistant integration split into a separate repository.
