Take your smart home automation to a new level with the SONOFF DualR3 Lite Smart Wi-Fi Switch. Designed as a flush-mounted dual relay module, the DualR3 Lite allows you to convert traditional switches into intelligent devices without changing the wall switch's appearance. This compact yet powerful device enables two-way control of two separate appliances, offering ultimate flexibility in lighting and motorized control systems.
Whether you're managing lighting from multiple locations or automating motorized curtains, blinds, roller shutters, or awnings, DualR3 Lite seamlessly integrates your existing home infrastructure into a smart, responsive, and voice-controllable system.
You can schedule the curtains to open with the sunrise, control window shades with your phone, or automate blinds with voice assistants like Alexa and Google Home. The dual-channel relays independently support up to 2200W per gang or 3300W total, making it powerful enough for most home applications.
Easy to install, DIN-rail compatible, and built for safety with flame-retardant PC V0 material, the SONOFF DualR3 Lite is a perfect choice for smart home DIYers looking for a reliable and powerful upgrade.
