HL_PAN4 (Wyze Cam Pan v4) - IOTC_ER_UNLICENSE on firmware 4.70.1.3311

[namcbrid-hash]

Describe the bug

Wyze Cam Pan v4 (model HL_PAN4) fails P2P connection with IOTC_ER_UNLICENSE (-10) on both latest and dev tags of docker-wyze-bridge v2.10.3. Camera is discovered and added to streams, but never connects.

Bridge version

v2.10.3 (tested both mrlt8/wyze-bridge:latest and mrlt8/wyze-bridge:dev, sha256 89f2439f... for dev)

Camera model

• Model: HL_PAN4 (Wyze Cam Pan v4)
• Firmware: 4.70.1.3311 (latest production as of March 2026)
• Nickname: "Kaydence"

Relevant log output

[+] Adding Kaydence [HL_PAN4]
[kaydence] [-10] IOTC_ER_UNLICENSE

PTZ endpoints (e.g. /api/ptz_position) return timed out — the camera never reaches a connected state.

What I tried

• Switched from latest to dev tag — same result, same error
• Camera connects and streams fine in the official Wyze app
• Other cameras (non-Pan v4) work as expected

Notes / Questions

A few things worth noting based on research:

1. HL_PAN4 doesn't appear in the bridge's supported cameras table — only Pan v3 (HL_PAN3) is listed as the newest supported Pan model. Is HL_PAN4 intentionally unsupported, or is this a TUTK license gap?

2. TUTK SDK version — Is there a plan to update the TUTK SDK version to support newer Wyze firmware? The HL_CAM4 firmware update issue (BUG: Wyzecam v3 and v4 no longer work with bridge after auto-firmware update #1438) also surfaced TUTK license/compatibility problems.

3. Workaround? — Is there any known workaround (e.g. firmware downgrade, specific env vars, network_mode: host) that has worked for HL_PAN4?

4. v4fix fork — Saw nickdnj/docker-wyze-bridge-v4fix which uses WebRTC via AWS Kinesis instead of TUTK for HL_CAM4. Does that approach extend to HL_PAN4? Any plans to incorporate WebRTC support for Pan v4 into the main bridge?

Thanks for maintaining this project!

I can confirm the issue is still there: [-10] IOTC_ER_UNLICENSE I'm using the same firmware, fresh setup this morning and it forced the firmware update so there is no way to avoid it.

I'm using the Home Assistant Docker Wyze Bridge version for mine.
