Intelligent circulating fan control solution helps brands upgrade.

Client Background & Challenges

Founded in 1998, AH is a landmark brand in the European high-end home appliance sector, specializing in indoor air circulation solutions. It enjoys a reputation as a "master of quiet operation" in markets such as Germany, France, and Northern Europe. However, its circulating fans have the following drawbacks:

• Loss of quietness due to outdated technology: The old product line used traditional AC motors and mechanical knob controls, with noise levels reaching 42-45 decibels when running at full load.
• Lack of smart home compatibility: The product lacks IoT connectivity and cannot be integrated into mainstream smart home ecosystems such as Apple HomeKit, Google Home, and Amazon Alexa.
• Energy consumption and environmental protection standards not met: Traditional AC motors have an energy efficiency rating of only E, which does not meet the latest EU energy efficiency standards for household appliances.
