Every Smart Home Automation Command for Cololight RGB Lights via Google Home and Alexa

Quick Answer

Cololight supports the full standard smart light command set via Google Home and Alexa: on/off, brightness percentage, colour by name or hue value, colour temperature in Kelvin, and scene activation by name. Scene commands require the scene name to match exactly what you named it in the Cololight app.

Google Home Voice Commands for Cololight 🎤

After linking your Cololight account in the Google Home app, every panel group appears as a named light device. Google Home supports these spoken commands natively: "Hey Google, turn on [device name]", "Hey Google, set [device name] to 50 percent", "Hey Google, set [device name] to blue", and "Hey Google, set [device name] to warm white". Colour temperature commands accept descriptive terms like warm, cool, and daylight, which Google maps to approximately 2700K, 4000K, and 6500K respectively. For scene activation, say "Hey Google, activate [scene name] on [device name]". If the scene was saved in the Cololight app as "Gaming Red", the voice command must say "Gaming Red" exactly. South African English accents are well-recognised by Google's speech model as of 2026, so enunciation issues are rare.

Alexa Voice Commands and Skill Setup 🔊

Enable the Cololight skill in the Alexa app under Skills and Games, then link your account. Alexa supports: "Alexa, turn on [group name]", "Alexa, dim [group name] to 30 percent", "Alexa, set [group name] to red", and "Alexa, turn on [scene name]". Alexa's colour naming is slightly more limited than Google's, accepting standard CSS colour names rather than arbitrary hues. For two-step commands like setting brightness and colour simultaneously, use an Alexa Routine that executes both actions in sequence with a 1-second delay between steps, which prevents command conflicts. Assigning your Cololight panels to an Alexa Group (e.g., "Gaming Room") allows multi-device commands: "Alexa, set gaming room to purple" adjusts all lights in that group.

Building Routines and Automations 🤖

Both Google Home and Alexa allow time-based and trigger-based routines. A practical SA gaming household setup: at 19:00 on weekdays, a Google Home routine dims the kitchen overhead lights, activates the Cololight "Deep Space" scene, and sets the TV backlight to ambient mode. Routines can also be triggered by other smart devices: linking a smart plug on your gaming PC to a routine means that when the PC powers on, Google Home automatically activates your preferred gaming light scene without any voice command. Alexa's Guard mode can additionally shift your Cololight panels to a slow red pulse when it detects unusual sounds while you are away, acting as a visible deterrent.

FAQ

Can Cololight scenes be activated through Google Home Routines without a voice command?

Yes. In the Google Home app, create a routine with a time or sunrise/sunset trigger, then add the action "Adjust lights" and select the Cololight device and scene. The routine fires automatically.

Does Cololight work with Apple HomeKit?

Cololight does not natively support HomeKit. Third-party bridges like Homebridge can add HomeKit compatibility, but this requires a always-on device running the bridge software such as a Raspberry Pi or a spare PC.

What happens to my Cololight lights if I lose internet while a routine is running?

If the routine trigger fires during an outage, the command will not reach the device. The lights remain in their last state. Once connectivity is restored, the next scheduled routine fires as normal.
