Release Notes

v0.5.4 — Native WebRTC for K2, async-safe frontend, dynamic box heater, and more

Native WebRTC camera for K2 family (no custom card required on recent Home Assistant).
Auto-detect camera type by model/probe: K1/K1C/K1 Plus use MJPEG; K2 uses WebRTC.
Async-safe Lovelace card deployment (no event loop blocking).
Box heater target entity now appears even if capability shows up after boot.
Friendlier camera diagnostics when signaling is unreachable.
Options flow modernization for HA 2025.12 compatibility.

WebRTC camera entity (K2)
- Implements native Home Assistant WebRTC offer/answer; plays in the more-info dialog and modern camera surfaces on recent HA.
- Attributes:
  - webrtc_url: webrtc://<printer-ip>:8000/call/webrtc_local#format=creality
  - signaling_url
  - error (set on signaling failures)
Camera Mode option (Integration Configure)
- auto (default) | mjpeg | webrtc
Delayed capability refresh for Box Target (K2)
- Dynamically adds number.*_box_target when maxBoxTemp appears after boot.

Camera auto-detection via model hint and quick signaling probe; fallback to MJPEG.
Async-safe frontend card deploy using executor to avoid event loop blocking.
Sensor robustness for object-related fields and optional box_temperature.
Number clamping safety; preserved > 40°C rule for K2 chamber heater.
Options flow uses non-deprecated pattern for HA 2025.12.

Eliminated async blocking warnings during frontend card deploy.
Native WebRTC eliminates “no stream/image” confusion and exposes useful error context.

Native WebRTC requires a recent HA. Older HA may show a static thumbnail; use webrtc_url with a compatible card if needed.
Perform a hard refresh after updating Lovelace resources if the UI looks stale.
