  • Connectivity

    Bluetooth

    Wireless connectivity protocol for control from a short distance.

    ZigBee

    Special connectivity network for smart devices that offers high stability and energy savings.

  • Compatible Application

    The compatible app that you download to your mobile phone to control the switch remotely.

  • Maximum Load

    It is the maximum amount of current that the switch can withstand without burning out. It shows you how many or how powerful devices you can connect: for simple lights, 10A is enough, while for power-hungry devices (such as a water heater) more Amperes are required.

    For example, a typical LED bulb (e.g. 10W) draws very little current, about 0.04 Amperes. This means that a standard smart switch of 10A is more than sufficient for its operation.
  • Dimensions 29x34x17mm

  • With Remote Control

    It allows you to control the switch remotely with a remote control, without needing your smartphone.

  • Smart Ecosystem

    Alexa

    The Amazon automation platform based on the Alexa voice assistant. It offers voice control capabilities and the creation of "Skills" for connecting and automatically coordinating multiple smart devices.
