ESP32 + Android Bluetooth Relay Control System with Global Timezone Support

Simple shell scripts to control relays connected to your raspberry pi with a via CLI, cron like scheduler, external switches, REST API and Web-UI.

Routines for managing switches and output relays connected to Arduino/Teensy microcontrollers

Python scripts for Raspberry Pi to control fan based on the CPU temperature

Relay Module Library for Arduino.

Two-Pi distributed dry-contact relay controller. Master handles logic, web UI, scheduling, notifications; remote slave drives the relay with an independent failsafe. Generic 2-wire input/output works for generator start/stop, pumps, valves, fans, irrigation, anything switched by a relay.

Arduino-based programmable timer switch using I2C LCD, push buttons, and relay control.

Automatic Sliding Door

MOLTINO is a versatile family of modular input/output (I/O) devices designed for measurement, control, and monitoring in industrial, academic, and development environments.

ESP32-based WiFi gate controller that enables remote activation of gates and doors over a local network. Built with ESP-IDF and implemented in a real-world automatic door system.

Advanced 4-Channel ESP8266 IoT Relay System featuring a real-time embedded dark mode UI, WebSocket sync, DS3231 RTC scheduling, and OTA updates.
