What to know before buying

The listing requires 2.4 GHz Wi-Fi and says 5 GHz is not supported. It also reports that some Android users may be unable to download the HBN app during an app upgrade, with Smart Life or Tuya Smart offered as alternatives.

Listing details to confirm

Listing details are inconsistent about the controller field, which names Amazon Alexa, while the title and feature copy also claim Google Home support. The app name varies between HBN Smart, Smart Life and Tuya Smart. Customer feedback also reports mixed functionality and connection experiences, so app setup and network compatibility are worth considering.

Who is it for?

People wanting app-based remote on/off control and schedules for compatible household appliances.
Smart-home users with a 2.4 GHz Wi-Fi network who use Alexa or Google Home.

Less suited to
