WiFi Sump Pump Monitor & Protector

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.

Why PumpFuse

How it works

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.

Not waterproof. For outdoor use, install in a waterproof enclosure using outdoor-rated extension cords. Prefer a purpose-built outdoor unit? See the PF03B outdoor model.

Frequently asked questions

Do I need to install water level sensors?

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.

Is there a subscription or account required?

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.

Can I use it outdoors?

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.

What pumps is it compatible with?

Sump, septic/ejector, well, and utility pumps rated 100–250V up to 1HP.
