Zephyr Fan Hours

Zephyr helps you schedule and track every fan in your home — room by room — so you always know how much air you're moving and what it costs. Add a schedule for any room: choose your fan type (ceiling, tower, window, exhaust, portable, or whole-house), set the hours per day, and Zephyr instantly shows you the estimated kWh consumption and monthly cost based on average US residential electricity rates. The Rooms tab gives you eight ready-made room profiles — Bedroom, Living Room, Kitchen, Bathroom, Office, Baby Room, Attic, and Garage — each with a sensible default fan recommendation and suggested run time. Tap any room to add its recommended schedule in one tap. The Energy tab summarises your current month at a glance: total fan hours, total kWh consumed, and estimated total cost, broken down by room and by fan type so you can see exactly where your ventilation budget is going. Everything works offline. No account required, no ads, no tracking.
