Automations, routines, and AI help
Automations decide whether your home feels smart or fussy. Google’s Gemini and Alexa’s routines make powerful flows more approachable. Apple favors simplicity and reliability. Home Assistant gives you total control with conditions, templates, and presence logic.
- Google Home: Tell Gemini the outcome you want. It drafts triggers and actions. You tweak and debug.
- Alexa: Broad routine options with voice and sensors. Great for renters and multipurpose rooms.
- Apple Home: Clean triggers and scenes that “just work.” Less fiddly than others.
- Home Assistant: Anything is possible. The learning curve is real.
Cameras, security, and event history
Camera experience varies. Nest shines for summaries and tags. HomeKit Secure Video keeps clips private. Alexa integrates many brands well but feels vendor-dependent. Home Assistant lets you unify feeds and storage locally.
- Google Home + Nest Aware: Person/vehicle/package tags and concise event summaries save time.
- Apple Home + HSV: Strong privacy and family sharing. Limited camera list, but reliable.
- Alexa: Broad camera support with solid notifications. Depth depends on brand.
- Home Assistant: Deep NVR options if you’re willing to configure.
Privacy, roles, and data control
Apple leads on privacy, with secure design and local processing where possible. Google clarifies roles and permissions. Alexa provides good controls, yet relies more on vendor clouds. Home Assistant puts privacy in your hands by default.
- Use roles and PINs to limit access to locks and cameras.
- Prefer Thread/Matter for local control and fewer cloud trips.
- Audit devices and routines quarterly to remove clutter.
