From the project

A smart thermostat built on the ESP32 platform featuring environmental sensing, e-paper/LVGL display, deep sleep power management, and multiple connectivity options (WiFi, Bluetooth, Blynk IoT).

A smart thermostat built on the ESP32 platform featuring environmental sensing, e-paper/LVGL display, deep sleep power management, and multiple connectivity options (WiFi, Bluetooth, Blynk IoT).

Designed to fit inside an existing thermostat housing, this project includes both the firmware and KiCad hardware design files.

- Environmental sensing via Bosch BME680 (temperature, humidity, pressure, air quality) - Display options: E-paper (GxEPD2) or LVGL-based display - Deep sleep with RTC memory persistence for battery efficiency - Task scheduler that survives deep sleep cycles - Multiple…
