Simple mount for converting an IKEA roller blind to a smart blind.
BOM:
1x 608 bearing
1x 6mm, 2GT214 timing belt
1x 20 tooth 2GT 6mm pulley for stepper motor
4x 3x16mm SHCS bolts
1x Pancake Nema 17 stepper motor & driver (I used a TMC 2208)
1x ESP32
Build Instructions:
- Loosely mount the motor to the base plate, with the belt around it's pulley
- Insert the 608 bearing into the printed pulley
- Install printed pulley on the base plate, while also installing the belt around the printed pulley
- Tension the belt by moving the motor down, and tightening it's mounting screws
- Remove the spring mechanism from the roller tube
- Remove the printed pulley and insert it into the blind's tube
- Replace the original tension mount (the mount with a small rectangular protrusion) with the printed base
- Mount the roller blinds using the original idler mount and the new printed mount, while also installing the belt around the printed pulley
- Connect the motor to the motor driver and the ESP32
- Install firmware of your choosing
- I used esphome with homeassistant
- the provided yaml file configures the esp32 properly as a shade for HA, and exposes 2 switches for calibraion
- turn on the calibration switch
- turn on the calibration button → shade will start moving downwards
- once the shades arrives at the bottommost location, turn on the calibration button again → shade will start moving upwards
- once the shade arrives at the topmost location, turn on the calibration button again
Config file and setup heavily based on Motor-On-A-Roller-Blind-for-ESPHOME
