ESP32 Offline & Threshold Alert Kit

Never miss it when your ESP32 goes silent.

The ESP32 Offline & Threshold Alert Kit gives your projects a simple, reliable way to notify you the moment something goes wrong — whether your device drops offline or a sensor reading crosses a threshold you set.

No paid dashboards. No subscriptions. Just code and a setup guide using free tools you can start with today (IFTTT, healthchecks.io).

Ready-to-use ESP32 code for offline detection and threshold-based alerts
Step-by-step PDF setup guide
Configuration using free services (IFTTT + healthchecks.io) — no ongoing costs
Easily customizable thresholds for your own sensors and use case

Who it's for:
Makers, hobbyists, and small IoT builders who want peace of mind without paying for a full monitoring platform.

An ESP32 board and a free IFTTT/healthchecks.io account.
