Smart blinds Alexa

Описание: How to make 2" blinds to open and close with Alexa or web server. I use ESP32 and TMC2208 Bipolar motor driver to make automatic shade control.
After assembling the hardware connected to the stepper and use the web server to turn motor in both direction before installing in it on shade, this should work without forwarding . Within Sketch I did taking care of last position of shade, also stepper only respond to consecutive command Open follow with Close or voice versa and repeated consecutive Open or Close will be ignored, also number of motor turns and status of last position have been saved within EEPROM on ESP32 that power interruption does not effect operation of system, After power restore the 1st thing that happen ESP read the last status of shade and saved number of motor turns before proceed to loop part of sketch.

PM me for copy of Sketch.
