| Nest Protect | Works Cloud | 3 units work via clunky cookie authentication; reliable in practiceSaved copyI have 3 nest protects at home and yes the procedure looks clunky but it works like a charm. I'm a complete beginner at Home Assistant but it just works. Excerpt saved from the Arctic Shift Reddit archive on 2026-10-23. | Reddit comment · 2025-01 | |
| Nest Protect (battery) | Works Cloud | Works in Home Bridged into HomeKit via Home Assistant | HACS integration trouble-free for years; cloud reliant, API future uncertainSaved copyI've got battery Nest Protects and use the HACS integration.
