Google Home 4.20 suggests automations for your devices

Google is rolling out suggested automations in Google Home app 4.20. In release notes posted on July 8, 2026, Google said Android and iOS users will begin seeing ready-made routines for jobs such as home security, morning schedules, and energy savings. The feature is rolling out globally over the coming weeks, so installing version 4.20 does not guarantee that the suggestions will appear immediately.

This is useful for a Matter home because the blank automation editor is often where a simple idea becomes tedious. Google's examples include turning cameras on at night, switching lights off when nobody is home, and playing music on a schedule. Its Google Home overview says the recommendations are based on the devices already in the home, and that a user can tap one to inspect and adjust it before saving.

The suggestion is still only a draft. A Matter light might offer on, off, brightness, and color controls, while a plug may only expose switching. Sensors, buttons, locks, blinds, thermostats, and bridged devices can provide different starters and actions depending on what Google Home supports for that exact integration. Google's automation documentation says its enhanced editor supports select device behaviors, not every capability from every manufacturer's app.

That distinction matters most when a suggestion uses presence, a lock, a camera, or an energy-related action. Check the named device and room, then read the starter, conditions, and actions before enabling it. A polished recommendation card does not confirm that a vendor-only scene, power reading, button press, or security setting has become portable through Matter. Google also says Home automations are for convenience, not safety or security-critical jobs, and may depend on internet, Wi-Fi, and third-party services.

Start with a routine that is easy to undo, such as switching off one Matter plug after everyone leaves or setting a light group at a fixed time. Run it manually, test the real trigger, and check that the right household members can edit it. Leave locks, cameras, heating protection, and other safety-critical behavior out of the experiment.
