No sensors. Real-time alerts to your phone. Prevent burnout, over-cycling and flooding.
The PumpFuse PF03 is a smart inline monitor that tracks your sump pump's real-time power usage and warns you before a small problem floods your basement — no float switches, no pit access, no subscription.
Your sump pump protects your home. PumpFuse protects your pump. It continuously measures pump power draw and compares it against customized upper and lower limits to alert on abnormal conditions — clogs, dry runs, stuck float switches, and power outages — before they become emergencies.
Works with sump pumps, septic/ejector pumps, well and utility pumps, and outdoor pumps in a waterproof enclosure. Supports 100–250V pumps up to 1HP.

No. PumpFuse monitors the pump's electrical power draw instead of water level, so there's nothing to place in the pit and no float switch to wire.
No. There's no login, no password, and no recurring fee. Your data is stored on a U.S.-based cloud and full history and analytics are free in the app.
The PF03 is not waterproof. It can be used outdoors inside a weatherproof enclosure with outdoor-rated cords, or you can choose the PF03B outdoor model with an IP44 housing.
