A sensor-monitoring service for garages and other vulnerable spaces, with live readings, history charts, and freeze, leak, and heat alerts.

Landing page captured for the 2026-10-12 issue.

For: DIY sensor builders and property owners monitoring cold or leak-prone spaces
Worth noticing: Its no-account simulator lets visitors trigger a cold snap and inspect multi-zone risk and JSON responses.

Field notes

The setup guide centers on a low-cost ESP32 and waterproof DS18B20 probe, with a free push device receiving sensor readings through an ingest key. The page also names Home Assistant, ESPHome, and MQTT as supported routes, and describes a dashboard with device health, feed status, freeze margins, and historical curves. It presents SMS alerts as a Pro-plan feature.
