This module connects to 2.4GHz Wi-Fi and allows users to turn devices on/off remotely, set schedules, and create smart scenes. Each of the four channels can be controlled independently, making it ideal for lighting, fans, pumps, or other appliances.
The 4CH R3 supports DIN rail mounting, making it easy to install in electrical panels for centralized control. It’s compatible with Alexa, Google Assistant, SmartThings, and Alice, allowing voice commands to operate individual channels.
Users can configure inching mode, which automatically turns off a channel after a set time—useful for devices like kettles or garage doors. The switch also supports interlock mode, ensuring only one channel is active at a time, ideal for motorized systems.
