See full description

  • Connectivity

    Wi-Fi

    The most common connectivity option for individual switches, as it connects directly to the router.

  • Usage

    Lighting

    For remote control of lamps and lighting fixtures.

    Garage door

    They allow remote control (opening and closing) of garage doors.

  • 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 90x34x34mm

  • 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.

    Google Home

    Google's platform for managing and controlling smart devices. It allows operation via Google Assistant with voice commands in Greek and the integration of the device into automated routines.

    IFTTT

    Automation ecosystem that connects the device with applications and other smart gadgets. Allows the creation of smart scenarios (Applets) for automatic operation based on location, weather, or other digital notifications.

    the analog switches are only connected in parallel to the outputs, so the app does not know whether the lights are on or off if you operate them from the physical switches, nor can you turn them off from the app if they have been activated from the physical switches.

    I have 7 Sonoff devices at home, all single-channel and one like this, the single ones work perfectly, the 4-channel is constantly offline, whenever it feels like it, it comes online, I'm thinking of replacing it and putting 4 singles in its place

    This particular model is the basic R3, not the Pro. It does not have 433MHz RF control as shown in the first image.
