ESP8266 based window blind control

Hardware

I am using a Sonoff DUAL R2. Two relays are needed to control the motor rotation direction.

The first FW flash needs to be done thru UART, shorting BUTTON 0 to GND. Subsequent FW updates can be done via OTA.

Push Button behaviour

• Short press: move up or down the blind (for debug purposes). Up / down direction is toggled at each button press.
• Long press (at least 6 seconds): reboot the module.
