The ability of the mmWave radar to track people within sensing range also enables another useful feature in smart thermostats – the screen wake-up on presence detection. This functionality makes sure that when someone enters or exits the room, the thermostat screen wakes up, providing users with real-time information about the indoor climate and any adjustments made. The integration of this dynamic feedback loop empowers homeowners to better understand energy usage patterns and makes it easier to optimize thermostat settings for improved comfort and efficiency.
