Google Home September 2026: Home MCP lets agents in, US only
Google posted Google Home release notes on 20 August, 2 September and 16 September 2026, plus a separate announcement for Home MCP. The headline is Home MCP, which lets an AI agent read and control your home but is limited to the US for now. Nothing was removed and nothing broke.
2026.9 Released 16 September 2026
Update now The headline: Google Home now has an MCP server that lets AI agents such as Claude read your devices and run them, but early access is limited to Premium Advanced subscribers in the US, so Australian households get only the smaller fixes for now.
Nothing to check. Every setup is clear to update.
The headline feature: an AI agent that can run your home
Google announced Home MCP alongside its 16 September release notes. MCP is the Model Context Protocol, a standard way for an AI agent to call tools, and Home MCP is Google's server for it. Any agent that can call MCP tools can connect, and Google's announcement names Antigravity, Claude, Hermes and OpenClaw. Once connected, the agent can see your devices and their event history and run actions on them, including Nest doorbells, thermostats and Matter bulbs.
Google's examples are practical: an agent can summarise what happened across your cameras and pull the clips, look back through device history to answer something like how many loads of laundry ran this week, play an audio message on a Google Home speaker when a background task finishes, or build a custom dashboard. There is no app toggle. You create a Google Cloud project set up for Home MCP, hand the configuration details to your agent, then sign in and grant permissions, with setup guides in the Google Home Developer Center. Google applies rate limits, prohibits sensitive actions such as unlocking doors, and warns that agents may behave unexpectedly.
Google says early access is rolling out in English to Google Home Premium Advanced users in the US. It is not available in Australia, and Google has given no date or plan for other markets. Premium Advanced is also the tier our August write-up flagged for AI descriptions of camera events.
14 smaller wins
The changes most people will notice day to day. Scan the tags for the areas you use.
Locks
Unlatch and unlock separately
Compatible European-style smart locks now let you control unlatching and unlocking independently, and the app shows states such as 'Unlocked and latched'. The 20 August notes name no models or countries, so check your own lock before you count on it.
Climate
One temperature unit everywhere
Temperatures in the app, in voice answers and on Google Nest devices now follow the unit you choose under Home Settings, then Temperature Units.
Gemini
Colour temperature by voice
You can now say something like 'make the living room lights 2700 kelvins' to set a light's white tone. This is a Gemini for Home Early Access change.
Gemini
Media and home commands in one sentence
Gemini on speakers and displays now understands combined commands such as 'Turn off the lights and stop the music' or 'Skip this song and turn on the backyard lights'.
Gemini
Better Spotify picks
Recognition of songs, artists and playlists improved, including requests like 'play my Liked songs on Spotify'. Liked songs and personal playlists need Personal Results switched on.
Gemini
Fewer awkward conversations
The 16 September notes cut unnecessary follow-up questions, stop the intermittent failure to launch TV streaming apps on smart displays, and reduce Live Mode interrupting itself.
Broadcast
Broadcast in two steps, and more reliably
You can say 'OK Google, broadcast message' and give the message as a separate follow-up, and broadcasts across the whole home fail less often. The one-sentence form still works.
Alarms and lists
Alarms and lists work again
Google fixed problems creating and editing alarms and lists, and corrected a Settings screen so it is clear Google Keep is still supported.
App
Widgets stop draining your battery
Home widgets now pause background updates while your phone screen is off, locked or on a screensaver, and refresh the moment you unlock. That also spares connected cameras.
App
Steadier accounts, tiles and setup
Switching between Google accounts throws fewer 'Home not found' errors and preference resets, sensor, camera and smoke alarm tiles no longer stay grey after you leave a device screen, Wi-Fi pairing stalls are fixed, and a startup crash on Google TV is gone.
Automations
Private routines stay private, and the editor is sorted
The app now respects visibility settings from partner apps, so private third-party routines stop cluttering your list. Starters, conditions and actions in the editor are now listed alphabetically.
Alerts
Smoke alarm status after it clears
Smoke and carbon monoxide notifications are being updated to show the device's current status after an alarm has been cleared. Google describes this as rolling out.
Cameras
Camera fixes on both phones
On Android, live tiles no longer go black when you return from full screen, history scrolling no longer freezes over gaps in recording, and live streams no longer stick at 360p. On iOS, the Live button now switches from a recording to the live feed, and controls stay visible when a camera is offline.
Google Home Premium
A warning before your plan lapses
An in-app alert now appears if a Premium payment fails, so you can update billing before losing camera history or other features.
Breaking changes
No breaking changes this month
Nothing is removed or renamed in 2026.9. Update whenever suits you.
Should you update?
Our verdict Update now
Update. Across the three sets of notes nothing was removed and nothing needs migrating. Home MCP will draw the attention, but it does nothing for an Australian household today: it is early access, English only, US only and Premium Advanced only, and Google has not said when or whether that widens.
What you will notice is smaller. The widget battery fix, the temperature unit setting and steadier account switching apply to everyone on the app. Most of the voice items are tagged Gemini for Home Early Access, so they apply to homes already using Gemini for Home. If yours is not, note that our August write-up recorded Google saying the move cannot be reversed.

Frequently asked questions
What version of the Google Home app is this?
Google does not publish an app version number with these release notes. Update through the App Store or Play Store and you will have it.
Can I use Home MCP in Australia?
Not yet. Google says Home MCP early access is rolling out in English to Google Home Premium Advanced users in the US, and it has not given a date or plan for other countries.
What is Home MCP, in plain terms?
It is a connector that lets an AI agent, such as Claude or Google's Antigravity, see your Google Home devices and their event history and run actions on them. You set it up through a Google Cloud project, not a switch in the app.
Do I need a subscription for the new voice features?
Google lists no plan requirement for them in the 2 September or 16 September notes. They are tagged Gemini for Home Early Access, so what matters is whether your home has moved to Gemini. Home MCP is the exception and needs Premium Advanced.
Does anything in these updates break my setup?
No. None of the three sets of notes removed a feature, dropped support for a device or asked you to change anything.
