Project covering automated automated blinds with Openhab
Published based on request on Openhab discussion forums
espRoller32 Arduino based sketch
ShadeEsp32Mini Kicad project for PCB With MH Mini ESP32 Board
ShadeEsp32V2 Kicad project for PCB Based on ESP32 Wroom module
PCBs I have made with my laser engraver with black masked , precision and allign was little bit limiting
We have 2 double windows in our kithen/living room. I have bought 2 sun stop blinds and I implemented as part of my home automation to enable privacy on windows coming from street and escpecially on window from south to limit sun which was lights directly to peoples sitting face to window. During summer I use them as aditional temperature and light for room.
Whole scheduling is based on openhab rules.
JGA25-12V chinese motors with encoder, appox 25rpm is fine
DRV8872 H-Bridge (for each motor)
Mini360 Buck step down module
AMS 1117-3.3V regulator
Some SMD and THT Passive parts according to schematic
Optionally
Omron G2MB 5V SSR Relay - we have small 220V led bulb as over window, which is also controlled by automation
