Thesada Documentation
Thesada is an open-source modular property monitoring platform built on ESP32 hardware with custom C++ firmware, MQTT over TLS, cellular fallback, and Lua scripting. Designed for rural and off-grid deployments where reliability matters.
What it does
- Monitors - temperature (DS18B20, SHT31), current (ADS1115 + CT clamp), battery voltage and charge state
- Alerts - Lua-defined alert rules with sustain, cooldown, and hysteresis via MQTT, Telegram, or webhook
- Logs - CSV data to SD card, logrotate included
- Updates - over-the-air via HTTP push or pull (TLS-verified, SHA256 checked, PROGMEM CA fallback)
- Scripted - Lua 5.3 runtime for custom rules without recompiling
