# Zemismart Blind Controller Protocol: RF command reconstruction

> Zemismart Blind Controller Protocol documents the 433.92 MHz OOK PWM messages used by Zemismart motorized blind remotes. It records pulse timing, payload fields and formulas for channel and button commands, with Python scripts to capture IQ samples and encode or decode transmissions.
