Control Elgato Key Lights with Alexa, Google Home & Apple Home

This guide walks you through connecting your Elgato Key Lights to Amazon Alexa, Google Home, and Apple HomeKit. You’ll learn the exact steps for each ecosystem, from initial setup in the Elgato Control Center app to voice commands and automations. No special hardware is needed beyond the lights themselves and a compatible smart speaker or hub.

What You’ll Need

• Elgato Key Light, Key Light Air, or Key Light Mini (firmware updated)
• The Elgato Control Center app (Windows, macOS, iOS, or Android)
• A Wi-Fi network (2.4 GHz or 5 GHz) that your lights and smart speakers can access
• For Alexa: An Amazon Echo or the Alexa app on your phone
• For Google Home: A Google Nest speaker/display or the Google Home app
• For Apple Home: An Apple HomeKit hub (HomePod, HomePod mini, or Apple TV) and an iPhone/iPad with the Home app

Step-by-Step

Initial Setup in Elgato Control Center

1. Download and install the Elgato Control Center app on your computer or mobile device.
2. Connect your Elgato Key Light to power and wait for it to appear in the app (it should show up automatically on the same network).
3. If prompted, update the firmware to the latest version—this is essential for smart home compatibility.
4. Give each light a clear name (e.g., “Key Light Left�) in the app. This name will appear in your smart home apps, so make it easy to say.
5. Note the IP address of each light (visible in the app’s device settings). You may need it for troubleshooting.

Connecting to Amazon Alexa

1. Open the Alexa app on your phone and go to Devices > the “+� icon > Add Device > Light > Elgato.
2. You’ll be asked to sign in to your Elgato account (create one if you don’t have it). The app will automatically discover your lights.
3. Follow the prompts to link your Elgato account. Once linked, Alexa will find your Key Lights and add them to your device list.
4. Group the lights in a room (e.g., “Studio�) for easier control. Say “Alexa, turn on studio lights� or “Alexa, set key light left to 50%.�

Connecting to Google Home

1. Open the Google Home app on your phone and tap the “+� icon > Set up device > Works with Google.
2. Search for “Elgato� in the list and select it.
3. Sign in with your Elgato account and authorize the connection. Your lights will appear in the app.
4. Assign each light to a room (e.g., “Office�). You can then say “Hey Google, dim the office lights� or “Hey Google, turn on key light air.�

Connecting to Apple HomeKit

1. Open the Elgato Control Center app on your iPhone or iPad (the mobile version is required for HomeKit setup).
2. Tap the gear icon next to a light, then select “HomeKit Setup.�
3. Tap “Add to Home� and follow the on-screen instructions to scan the HomeKit setup code (printed on the light’s base or in the box).
4. Assign the light to a room and give it a name. Repeat for each light.
5. Once added, you can control the lights via the Home app, Siri (“Hey Siri, turn off the key lights�), or automations.

Common Mistakes

• Skipping firmware updates: Older firmware may not support smart home integrations, so always update before attempting to connect.
• Using the wrong network: If your phone and lights are on different Wi-Fi networks (e.g., guest network), discovery will fail. Keep everything on the same network.
• Naming lights vaguely: Names like “Light 1� are hard to use with voice commands. Use descriptive names like “Key Light Right.�
• Forgetting to link the Elgato account: Both Alexa and Google Home require you to log in to your Elgato account. If the skill isn’t working, re-link the account.
• Expecting full color control: Elgato Key Lights only support white temperature and brightness—they are not RGB. Voice commands for color will not work.

Tips

• Use groups: In Alexa, Google Home, and Apple Home, create a group for all your Key Lights so one command controls them all.
• Set scenes: In the Elgato Control Center, you can create preset scenes (e.g., “Streaming,� “Video Call�). These scenes appear as “scenes� in Alexa and Google Home, allowing you to activate them with voice.
• Automate with schedules: In Apple Home, you can create automations like “Turn on Key Lights at 6 PM� or “Turn off when I leave.� Google Home and Alexa also support schedules via routines.
• Use the Elgato Stream Deck: If you have a Stream Deck, you can control the lights directly and also trigger smart home scenes, but that’s separate from voice control.
• Keep the app installed: Even after setup, you’ll need the Control Center app for firmware updates and advanced settings like precise color temperature.

Troubleshooting

• Light not discovered: Restart the light (unplug for 10 seconds) and restart the smart home app. Ensure the light is on the same Wi-Fi network as your phone/speaker.
• Alexa/Google says “device is unresponsive�: Check that the Elgato Control Center app can still see the light. If not, power-cycle the light. Also, re-link the Elgato skill in the Alexa or Google Home app.
• HomeKit setup code not working: Make sure you’re using the mobile Control Center app, not the desktop version. If the code is scratched, contact Elgato support for a replacement.
• Voice commands work but dimming doesn’t: Some voice platforms interpret “dim� as a percentage. Say “set brightness to 50%� instead. Also, ensure the light’s firmware is up to date.
• Lights disappear after a router change: Reconnect the lights to the new Wi-Fi using the Control Center app, then re-link the smart home integrations.

Frequently Asked Questions

Can I control Elgato Key Lights with Siri without a HomeKit hub?

No. Apple Home requires a HomePod or Apple TV as a hub to control devices remotely and to enable automations. Without a hub, you can only control them when you’re home and on the same network.

Do Elgato Key Lights work with Google Home without a hub?

Yes, Google Home works without a separate hub. The Google Nest speaker or display acts as the hub, and you can also use the Google Home app on your phone.

Can I use multiple Elgato Key Lights with one voice command?

Yes. In each ecosystem, you can create a group (e.g., “Studio Lights�) that includes all your Key Lights. Then say “turn on Studio Lights� to control them all at once.

Why can’t I change the color of my Key Light with voice?

Elgato Key Lights are white-light only (they have adjustable color temperature, not RGB). Voice assistants can only adjust brightness and on/off state, not color temperature, unless you use a scene that you preset in the Control Center.

Do I need to keep the Elgato Control Center app running?

No, the app does not need to be running for voice control to work. The lights connect directly to your Wi-Fi and the smart home cloud. However, you may need the app for firmware updates or to change settings.

Can I control Key Lights with both Alexa and Google Home at the same time?

Yes, you can link your Elgato account to both Alexa and Google Home simultaneously. The lights will appear in both apps, and you can use either voice assistant.
