Trådfri

Trådfri is a smart home product line from the Swedish furniture retailer IKEA. It allows users to control lighting wirelessly, offering features like dimming, changing color temperature, and even selecting from a spectrum of colors for certain bulbs. The system is designed to be accessible and affordable, making smart home technology more attainable for a wider audience.

The core of the Trådfri system relies on a wireless gateway that connects to a home's router. This gateway then communicates with Trådfri bulbs, lamps, blinds, and other accessories using the Zigbee wireless protocol. Control is typically managed through a dedicated smartphone app, which allows users to group devices, set schedules, and create scenes for different moods or activities.

In addition to the app, IKEA also offers physical remotes and motion sensors that can control Trådfri devices without the need for a smartphone. This provides alternative control methods for users who may prefer physical interfaces or for guests. The Trådfri ecosystem is designed to be expandable, allowing users to add more devices over time. It also integrates with other smart home platforms, enabling voice control through assistants like Amazon Alexa and Google Assistant. The name "Trådfri" itself is Swedish and translates roughly to "wireless" or "cordless," reflecting the product's focus on wireless connectivity.
