Automatic Smart Roller Blinds Mod

I bought these blinds very cheaply from amazon and automated them using Nema17 motors and ESPHome. Many cheap blinds come with exactly the same layout. You will need some experience with electronics to make this project work. Components You will need the following components: Roller Blinds Nema 17 Stepper ESP32 Board as Controller (I used a tiny ESP32-C3) Stepper Driver ( A4988 or TMC2209 ) - I recommend the TMC, as they are way more quiet 7x M3 countersunk screw 12V Power Supply Step Down Converter Wiring The stepper driver and ESP are connected like this: Stepper Driver Connected to DIR PinESP32 - GPIO5STEP PinESP32 - GPIO6SLEEP PinESP32 - GPIO21VINPower Supply +GNDPower Supply - Also hook up the Step Down Converter to supply 5V to your ESPs 5V Pin Assembly You will need to take apart the pulley part of the blind and insert the half where the cord goes into the large gear. Software You can use ESPHome to programm your ESP. Take a look at my ESPHome Config as a reference and modify it to your liking.
