Sump Pump Monitor & Alarm (Outdoor)

IP44 weather-resistant. Built for pits, patios and garages.

The PumpFuse PF03B is the outdoor-ready version of our smart sump pump monitor. Its IP44-rated housing resists splashing water and humidity — no separate enclosure required — while it watches your pump's power draw and alerts you to trouble.

Why PumpFuse PF03B

How it works

Your eyes on the pump, even when you're away. Plug in PumpFuse, connect to Wi-Fi, review usage logs, and set alerts in the PumpFuse app. It delivers real-time updates and customizable alerts straight to your phone over a secure, fast local network.

Indoor install instead? The PF03 indoor model covers the same features for dry indoor locations.

Frequently asked questions

Can I use it outdoors without an enclosure?

Yes. The PF03B has an IP44-rated housing that resists splashing water and humidity, so it's suited to covered patios, pump pits and garages without a separate enclosure.

What's the difference between PF03 and PF03B?

Same monitoring features — the PF03B adds a weather-resistant outdoor housing. The PF03 is the indoor model.

Do I need water level sensors?

No. It monitors the pump's power draw, so there are no float switches or in-pit sensors to install.
