Scenarios
What an alert looks like when something fails
Illustrative walkthroughs, not customer accounts: a heater trips, a vent sticks open, a pan goes wet. Each shows the probe setup, how the alerts play out, and why it matters.
Scenario · Heated garage with plumbing, cold climate
A garage heater trips at 2 a.m.
Scenario: a garage heater fails overnight in a cold snap. How an ESP32 probe, a 34°F freeze threshold, and SMS alerts buy time before pipes freeze.
Scenario · Vacation cabin, empty most of the week
The cabin furnace quits mid-week
Scenario: a power blip resets the furnace in an empty winter cabin. A crawlspace probe and email and push alerts catch it days before your next visit.
Scenario · Homelab closet next to a garage
A closet fan dies before the weekend
Scenario: a homelab closet fan fails while you're away. A ProbeHarbor heat rule and a Home Assistant webhook power down gear before it overheats.
Scenario · Attached garage with a water heater
The same corner dips below 34°F every clear night
Scenario: repeat freeze alerts in an attached garage. How ProbeHarbor history and CSV export point to a drafty door seal before supply lines ice.
Scenario · Crawlspace under a house, cold climate
A crawlspace vent sticks open overnight
Scenario: a foundation vent sticks open on a cold night. How a waterproof DS18B20 on the supply line and ProbeHarbor freeze alerts give you time to close it.
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.
Scenario · Garage with a water heater and storage
A water heater drips at 3 a.m.
Scenario: a garage water heater's drain valve drips overnight. A flood contact in the pan alerts you before the slab and stored boxes get soaked.
