Direct Drive Motorized Blind Controller ### Key Features: 1. No bearing or gear required due to high torque of 12v 28BYJ-48 stepper motor, capable of smoothly opening and closing 60 cm blinds. 2. Specifically designed for Leroy Merlin blinds; simply remove the plastic chain and attach the motor (refer to photos). ### Adapted Fork Utilizing an adapted fork, I control three motors from a single ESP board via MQTT and Web UI: https://github.com/eg321/esp32-motorized-roller-blinds. ### Modified Fork Features: - Supports ESP32 (ESP8266 should work as well) for easy connection of up to 3 steppers with 4-pin connectors. - Utilizes "CheapStepper" library, allowing configuration of rotation speed; search for "setRpm(30)" lines and adapt accordingly for your motors. - Code optimized for asynchronous stepper control, enabling parallel operation without speed loss. - Switched to a different Wi-Fi library, providing compatibility with ESP32 as well as similar functionality to the previous "WiFi manager". - Added "STOP" command for OpenHab compatibility; refer to OpenHab config examples. - Includes HomeAssistant support with separate MQTT topics for blinds position (out1, out2, out3); see HomeAssistant config examples.
