Your camera's wrong password error can be three defaults deep

说明与用途

两台 Tapo C210 摄像头因三个隐藏默认设置导致拒绝正确密码：禁用的兼容性切换、Home Assistant 中错误的用户名以及 AdGuard 规则错误。启用切换、使用正确凭据并清理 AdGuard 规则恢复了摄像头功能，避免了 70 分钟的停机。

问题

Two Tapo C210 cameras on a home network rejected the correct password, causing a temporary suspension and a 70‑minute service outage.

结果

Enabling the Third‑Party Compatibility toggle, correcting Home Assistant credentials, cleaning AdGuard rules, and reducing container memory usage restored camera authentication, automated workflows, and prevented a 70‑minute outage.

工作流

• 1. Identify the "Third‑Party Compatibility" toggle in the Tapo app and enable it.
• 2. In Home Assistant, use the camera’s TP‑Link account email as username, set "skip_rtsp" to true, and leave the cloud password empty.
• 3. Clean AdGuard user_rules by removing invalid lines, keeping 65 valid rules, and restart the container.
• 4. Verify DNS blocks for TP‑Link domains and confirm cameras are DNS‑quiet.
• 5. Adjust Frigate and other containers to reduce memory usage (720p stream, 5 fps detection, 3 GB memory cap).
• 6. Test PTZ, automations, and recordings to ensure functionality.

证据

With it off, the camera's control API rejects every credential, the correct password included.

Home Assistant's Tapo integration ships cloud setup steps that hardcode the username as "admin".

My AdGuard user_rules section had python-source garbage sitting in it, leftover lines from an earlier quoting crash.

The box runs 7 GB total RAM, with ~1.7 GB of that already in swap even at idle.
