Motorized roller blinds (Leroy Merlin version)

thingiverse

Remix from https://www.thingiverse.com/thing:2392856 thing. ### Differences: 1. Direct drive. So, no needs in bearing and gear. 12v 28BYJ-48 stepper motor torque is enough to easily open/close my 60 cm blinds with quite well speed. 2. It's designed to be used with blinds from Leroy Merlin. Just remove plastic chain and attach motor (see photos). You can revert all changes back in any time. I believe it's quite clear from photos. I'm using the adapted fork to control 3 motors from single ESP board (MQTT and Web UI): https://github.com/eg321/esp32-motorized-roller-blinds ### Some changes of that fork: - Support of ESP32 (ESP8266 should work too). It makes possible to easily connect up to 3 steppers with 4-pins connectors. - Switched to "CheapStepper" library. It allows to configure rotation speed (grep for "setRpm(30)" lines - maybe you'll need to adapt it for your motors). - Code was adapted for asynchronous control of steppers. Your steppers can work in parallel without loosing speed now. - Switched to another Wi-Fi library. In general it works like previous "WiFi manager", but supports ESP32 also. - Added "STOP" command for OpenHab compatibility. See OpenHab config examples. - HomeAssistant support. There are separate MQTT topics for blinds position now (out1, out2, out3). See HomeAssistant config examples.
