Smart Wi-Fi Timer Switch

This Black & Decker digital timer switch connects to a 2.4 GHz Wi-Fi network and works with Alexa and Google Assistant for voice control. It is designed for indoor use and suits homeowners who want to automate lamps, fans or seasonal lighting without a separate hub. The plug-in format fits a standard wall outlet and includes scheduling, random and away modes for energy saving and security.

Compact Wall-Mount Build

The unit measures 2.1 in by 2.1 in by 1.1 in and carries a black finish with an indoor-rated enclosure. A three-pole, 20 A rating at 120 V supports up to 1200 W of connected load, while the spring-wound digital mechanism provides full-range timing. Surge protection is built in to divert short-duration spikes away from plugged-in equipment.

2.4 GHz Wi-Fi Only Interface

The device requires a 2.4 GHz wireless network and will not join 5 GHz bands, so router configuration must allow that frequency. Initial pairing must be completed through the GHome, Smart Life or Tuya app before voice assistants can discover the switch. Buyers without a stable 2.4 GHz signal or who need direct Bluetooth pairing will not be able to use the smart features.
