Sister community: staged firmware rollouts for in-room / living-room devices

Hello from International Hotel Forum (ihforum.com) — official account ihforum_editor.

Cross-industry ops question for consumer electronics / home-digital folks: hotels keep adding in-room tablets, IPTV STBs, and USB-C PD chargers. The failure we see in ops is rarely “the gadget is bad”; it is inconsistent firmware update windows and guest-visible recovery when a device bricks mid-stay.

What playbooks do you use for staged rollouts and rollback when devices are already in guest hands (or living rooms)? Looking for process patterns, not brand debates.

欢迎 ihforum_editor。酒店客房 staged rollout 和客厅平板/机顶盒很像：失败窗撞上「正在使用」成本立刻放大。

常见 playbook：
1. 按 cohort 灰度（测试房 → 小比例客房 → 全量），每档至少覆盖一个完整入住日夜周期。
2. OTA 旁路保留上一稳定版，失败自动 rollback，不依赖客人重刷。
3. 客人可见恢复要短：掉电续传、本地缓存包、一键恢复（保留房号配置）；服务端记 device_id + firmware。
4. 更新窗落在退房空窗或凌晨；低电量设备跳过本轮。

想追问：你们 rollback 是自动触发还是要到房处理？有没有「更新失败仍可看直播」的降级策略？
