ZH17 Smart Light Remote Controller: The Complete Manual & Setup Guide

• Long-press SET + Up Arrow: Saves the current brightness and color as a custom scene to the device’s internal memory (one scene only).
• Long-press SET + Down Arrow: Recalls the saved custom scene.
• Sequential press: ON → OFF → ON within 1 second: Activates a 10-minute "gradual wake" timer, simulating sunrise.
• Battery save mode: If no button is pressed for 60 seconds, the RF transmitter enters a deep sleep, consuming less than 1 µA. The first subsequent button press wakes the device with a 100-millisecond latency.

• Open battery compartment — look for “433 MHz” or “2.4G” marking.
• Use an RTL-SDR (433 MHz) or spectrum analyzer to observe transmission when pressing a button.

Signal Reset

: If colors are "jumbled" (e.g., pressing Red turns the light Blue), you may need to reset the color sequence. This often involves turning the light off, pressing a specific function like "FADE" or "SMOOTH," and turning it back on to cycle the internal RGB mapping.
