Scenario · Detached shop with a utility sink

A forecast warning, then a tripped heater

Scenario: a detached shop heater trips its GFCI on a forecast cold night. Forecast warnings cover the day before; threshold alerts cover the night of.

Illustrative scenario. This is a walkthrough of how ProbeHarbor behaves in a common failure, not an account from a real customer. The features, thresholds, and plan limits are real.

The setup

  • Wi-Fi ESP32 above the utility sink; second probe near the overhead door
  • Forecast freeze warnings (Member) plus email
  • Vacation mode off before a trip, so alerts keep flowing

How it plays out

  1. Wed: A forecast warning flags Thursday's overnight low; the owner confirms the heater is on.
  2. Thu 1:50 a.m.: The heater trips its GFCI; the shop crosses 34°F and the email goes out.
  3. Thu 2:15 a.m.: The owner resets the circuit through a smart plug before the sink line freezes.

Why it matters

Detached buildings lose heat fast. A forecast warning covers the planning window; the threshold alert covers the failure itself.

Real outcomes depend on sensor placement, thresholds, and how quickly someone can respond.

FAQ

Do detached garages need two probes?

One near the pipes or sink is enough to start. A second near the door catches drafts the back wall never sees.

Is Free enough for a detached shop?

Free email alerts work. Member adds forecast warnings, which help when you are away and want notice before the overnight low.
