Google Home updates Gemini: smart home now understands 'ocean color' and precise temperatures

Google updated Home with Gemini in April 2026: now the smart home understands "ocean color" and precise temperatures

Google released an update to the Google Home app in April 2026, after which the Gemini voice assistant more accurately recognizes commands for the smart home — to the point where a user can ask to "heat the oven to 350 degrees" or select lighting that matches the description "ocean color".

What changed in light descriptions

Gemini in Google Home now selects a specific lighting shade based on a verbal description of a scene, rather than only from a name in a pre-defined list. Previously, users had to choose a color from a limited set of presets or name it precisely — now it's enough to describe the image. For example, the phrase "make the light like ocean color" causes the assistant to independently select an appropriate blue or turquoise shade for connected smart lamps.

Google described this and other changes in the Google Home release notes for March 2026, noting that they make commands "more natural and reliable." User Anish Kattukaran also wrote about the update on social media platform X, drawing attention to the assistant's changed behavior before the official announcement.

"The update makes controlling a smart home with

Gemini more natural and reliable," — according to the Google Home release notes for March 2026.

How appliances and climate control are now set up

Gemini learned to accept precise numerical commands for household appliances and climate control instead of approximate phrasing. A user can tell the assistant "heat the oven to 350 degrees" — and Gemini will set exactly that value on the connected smart oven, rather than rounding it to the nearest preset like "high heat" or "medium heat".

Similarly, you can now set a specific humidity percentage in the house instead of choosing from general modes like "drier" or "more humid". Precision in specific numbers is especially important for scenarios like baking or canning, where a deviation of just a few degrees can spoil the result, whereas previously voice assistants more often rounded such commands to the nearest pre-set level.

Google also improved recognition of specific devices: according to the company, the assistant more accurately determines which exact lamp, thermostat, or device a command refers to, even if the house has several similar devices of one type and previously Gemini could confuse them.

• Google Home app update was released in April 2026
• Gemini selects a light shade based on a scene description, for example "ocean color"
• The assistant performs precise numerical commands like "heat the oven to 350 degrees"
• The ability to set a specific humidity percentage instead of general modes has appeared
• User Anish Kattukaran first wrote about the changes on X, Google confirmed them in the March 2026 release notes

What this means

Google is gradually moving away from rigid trigger commands in home management: instead of memorizing exact phrasings, the user describes the desired result in words or names a specific number, and Gemini translates this into settings — temperature, humidity, or light shade. For Google Home smart home owners, this means less trial and error with voice control: you don't need to find the exact phrase the assistant will understand — it's enough to describe the desired result the way you would describe it to another person, and Gemini will translate this description into specific device settings.
