[0.9.6] - 2026-06-10

List of issues (0.9.6)

Added

• Direct WebRTC camera mode (idea recycled from change unsupported creality go2rtc format to webrtc connection with browser behavior #95, thanks @erus71an):
  • New opt-in "WebRTC direct, no go2rtc" camera mode that signals the printer's WebRTC endpoint directly from Home Assistant (browser-style base64-JSON SDP on :8000/call/webrtc_local), bypassing go2rtc entirely.
  • Available as an alternative for any WebRTC-capable printer — try it if the default go2rtc path doesn't work on your firmware (e.g. newer K1C). The K2-family go2rtc path is unchanged and remains the default.
  • The frontend offer is reduced to video-only, wrapped/unwrapped as the printer expects, and the answer's media-line order is rebuilt to match Home Assistant's original offer.
• Custom camera URL mode ([FR] IP Camera support #92, thanks @OptimusGREEN):
  • New "Custom camera URL" mode to point the camera at any external stream — http(s) MJPEG/snapshot URLs are served directly, and rtsp:// (and similar) streams are ingested through go2rtc.
  • Useful for printers without a built-in camera, or to substitute an existing IP camera.
• Spanish translations (es.json, thanks @ofdezdz / Óscar Fernández Díaz):
  • Adds a full Spanish translation of the integration's config and options UI, extended to cover the reorganized options menu and the new custom-camera-URL field.

Changed

• Options flow reorganized into a menu:
  • The printer Options dialog is now a menu with Camera, Notifications, Power switch, and Connection & performance sub-pages.
  • Each sub-page loads fresh, so mode-dependent fields are always correct — previously a single combined page couldn't re-render when the camera mode changed, leaving stale/irrelevant fields (e.g. go2rtc fields showing while "Custom URL" was selected).
  • Submitting a sub-page stages its changes and returns you to the menu (the back arrow returns without staging); Save and apply writes everything at once, so the printer reloads only once no matter how many sections you edit.
• Camera options refresh:
  • The camera-mode dropdown now lists Auto, MJPEG, WebRTC (go2rtc), WebRTC direct, and Custom URL, with clearer labels and help text.
  • The custom-URL field appears when the custom mode is selected, with validation for a complete URL.
  • Auto-detection now probes both /call and /call/webrtc_local WebRTC signaling endpoints.
• WebSocket handshake parity:
  • The client now advertises the printer web UI's wsslicer subprotocol on the WebSocket handshake. Servers that don't use it simply ignore it (RFC 6455), so this is compatible with existing printers.

Fixed

• WebSocket availability now requires real data:
  • The printer is reported available/connected only after the first valid telemetry frame, not on the bare TCP/WebSocket handshake — preventing brief "available" flashes against a socket that never streams data.
  • Reconnect backoff is reset only after a connection survives at least 10 seconds, so rapid connect/drop flapping keeps backing off instead of masquerading as healthy reconnects.
  • The heartbeat watchdog measures silence from the connect time until the first frame, avoiding a premature "connection dead" verdict right after connecting.

Internal

• [Regression] 0.9.3 breaks K2 Combo camera with default embedded go2rtc (0.9.2 works) #88 diagnostics: added debug logging of the negotiated WebRTC video codec/profile on stream start, to help diagnose the brief pre-keyframe visual artifact reported on some K2 cameras (no behavior change).
