Overview

Features

Bluetooth 5.2 SIG Mesh communication protocol, with strong networking capabilities and reliable and stable local control;
Supports use with LED controller B5-3A and intelligent touch panels EB1/EB2/EB5 to achieve intelligent lighting control;
When paired with Bluetooth lighting fixtures, it enables control of light switching, dimming, and color adjustment;
Combined with a smart gateway, it can achieve local automation/cloud automation control methods;
Supports local scenes, operates without a gateway, and remains controllable during network outages, offering faster and more stable performance;
Supports battery level detection – when the remote control's battery is low, the indicator light flashes to remind users to replace the battery;
Equipped with a dedicated wall-mounted base, it allows flexible selection of wall-mounted or desktop use to meet diverse usage needs.
