Google Home updates Gemini: the smart home now understands "ocean color" and exact temperatures

In April 2026, Google released an update to the Google Home app that makes the Gemini voice assistant more precise at interpreting smart home commands. A user can now ask it to "preheat the oven to 350 degrees" or to set the lighting to match a description like "ocean color".

What changed in lighting descriptions

Gemini in Google Home now picks a specific shade of light from a verbal description of a scene, not only from a color name on a fixed list. Previously, users had to choose a color from a limited set of presets or name it exactly. Now it is enough to describe the look. For example, the phrase "make the light the color of the ocean" prompts the assistant to choose a suitable blue or turquoise shade for connected smart bulbs on its own.

Google described this and other changes in the Google Home release notes for March 2026, saying they make commands "more natural and reliable". The update was also noted on X by user Anish Kattukaran, who spotted the assistant's changed behavior before the official announcement.

"The update makes controlling your smart home with

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

How appliances and climate are now configured

Gemini now accepts exact numeric commands for household appliances and climate control instead of approximate phrasing. A user can tell the assistant "preheat the oven to 350 degrees", and Gemini will set exactly that value on a connected smart oven rather than rounding it to the nearest "high heat" or "medium heat" preset.

Similarly, users can now set a specific humidity percentage in the home instead of choosing from generic modes like "drier" or "more humid". Precise figures matter especially for tasks like baking or canning, where a deviation of just a few degrees can ruin the result, and voice assistants previously tended to round such commands to the nearest preset level.

Google also improved recognition of specific devices. According to the company, the assistant is better at identifying which lamp, thermostat or appliance a command refers to, even when a home has several similar devices of the same type that Gemini could previously confuse.

• The Google Home app update was released in April 2026
• Gemini picks a light shade from a scene description, for example "ocean color"
• The assistant carries out exact numeric commands such as "preheat the oven to 350 degrees"
• Users can now set a specific humidity percentage instead of generic modes
• User Anish Kattukaran was the first to write 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 control. Instead of memorizing exact phrasing, users describe the result in words or state a specific number, and Gemini translates that into settings: temperature, humidity or light shade. For Google Home owners, this means less trial and error with voice control. There is no need to hunt for the exact phrase the assistant will understand. It is enough to describe the desired result the way you would describe it to another person, and Gemini will translate that description into specific device settings.
