Opera GX: The First Browser That Integrates with Your Smart Home and Home Assistant
Have you ever imagined that your web browser could turn off the lights in your room, activate a full privacy mode when someone opens the door, or manage your laptop battery? It may sound like science fiction, but it is now a reality. In this article, I explain how Opera GX has changed the game by becoming the first browser that can act as a smart device inside your Home Assistant ecosystem.

VideoWhat is Opera GX and why is it different?
Many people know Opera GX as the “browser for gamers”, and not only because of its aggressive and highly customizable look. Its real value is control:
- GX Control: lets you limit CPU, RAM and bandwidth usage so the browser does not slow down your games or work.
- Built-in privacy: includes a free VPN and a native ad blocker.
- Sidebar: direct access to Discord, WhatsApp, Spotify and Twitch without switching windows.
But what really blows the minds of home automation enthusiasts is its ability to communicate through the MQTT protocol.
The Magic: Home Assistant Integration via MQTT
Thanks to the Opera GX Smart Home extension and MQTT support, the browser stops being a passive tool and can send and receive real-time data.
What sensors does Opera GX expose to Home Assistant?
Once configured, you will be able to see these sensors on your Home Assistant dashboard:
- Number of open tabs.
- Device battery level.
- Theme color, also known as Accent Color.
- Playback status, for example if you are watching a video.
Real Automation Ideas
This is where your imagination is the limit. In my setup, I have already implemented several automations:
- Panic Mode: if a door sensor detects someone entering the room, Home Assistant sends a command to Opera GX to activate Panic Mode and instantly hide all tabs.
- Browser Ambilight: I created an automation where my RGB lights, using WLED, automatically change color based on the visual theme selected in Opera GX.
- Battery Care: if Opera’s battery sensor detects that my laptop reaches 80%, Home Assistant turns off the smart plug to extend battery lifespan.
- Cinema Mode: when the browser detects that I am watching a video, the blinds go down and the ambient lighting adjusts automatically.
Step-by-Step Setup Guide
To replicate this at home, follow these steps:
1. Prepare Opera GX
- Download and install Opera GX.
- In settings, find the Features section and enable Early Bird.
- Look for the MQTT Support option and restart the browser.
- In the new Smart Home menu, enable MQTT and enter your server IP, usually your Home Assistant IP address, and your credentials.
2. Extension and Home Assistant
- Install the official Opera GX Smart Home extension from the Opera add-ons store.
- In Home Assistant, go to Settings > Devices & Services > MQTT.
- Your browser will appear there as a new device with all its sensors and controls!
Conclusion
Opera GX has proven that the browser can become a key part of the digital home. It is no longer just a window to the world, but another sensor and actuator that reacts to your needs.
