A simple integration to allow Home Assistant to communicate with Vegetronix HegeHubs.

Production-grade ESP8266 IoT Smart Relay Controller — 1-4 channels, bilingual AR/EN, MQTT + Home Assistant, PWA, OTA updates

ESP32 + Android Bluetooth Relay Control System with Global Timezone Support

A simple integration to allow Home Assistant to communicate with Vegetronix HegeHubs.

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

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.

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.

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

Relay Module Library for Arduino.

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

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

Open replacement controller board for surplus Motorola PMUN1046A relay boxes: ESP32-C3, CANopen control, 10 x 15 A channels. Independent project, not affiliated with Motorola Solutions.
