Elite Aria smart fan
Elite Aria is perhaps the smartest indoor fan on the market. The fan automatically adjusts the fan speed based on speed, power, heart rate or body temperature. The fan communicates with ANT+™ FE-C and ANT+ speed sensors, ANT+™ power meters, ANT+™ and BLE heart rate belts and ANT+™ body temperature sensors and adjusts the fan speed based on the information received from them. The sensor can also be built into the training resistance (speed and power), so separate sensors are not necessarily needed.
The fan can also be easily controlled via Elite's My E-Training app without a paid subscription. Of course, you can also use Aria manually from the fan's control panel.
