Customer story

“We got the text before the pipes froze”

A detached garage workshop in Minneapolis — unheated except for a small space heater on a timer. When a polar vortex dropped outdoor temps to −15°F, the heater failed overnight.

The setup

  • ESP32 + DHT22 pushing every 5 minutes to ThermalTrace ingest
  • Freeze threshold at 34°F with Pro SMS + Telegram routing
  • Weekly digest for the household; share link for a neighbor who watches the house

Timeline

  1. Day −30: ESP32 installed, freeze threshold set to 34°F, Pro trial started.
  2. Day −7: SMS + Telegram tested with a manual “test alert” from the dashboard.
  3. 2:14 a.m.: Garage hits 33°F — SMS to both owners, Telegram to family channel.
  4. 2:22 a.m.: Smart plug restarted; dashboard confirms recovery above 38°F.
  5. Next morning: CSV export reviewed; subscribed to Member for winter history.

“We would have lost a full day of workshop time — and maybe a pipe — if the text hadn’t woken us up.”

— Homeowner, Minneapolis metro (name withheld)

What happened

At 2:14 a.m. the garage reading crossed 33°F. SMS fired to both owners; Telegram posted to a family channel. They restarted the heater remotely via a smart plug and confirmed recovery on the live dashboard before pipes in the shared wall had time to freeze.

Typical Pro trial → Member or Pro subscription after winter. Your results depend on sensor placement and alert thresholds.
