ATOM Socket is a smart power socket adapted to ATOM main control. Built-in HLW8032 high-precision energy metering IC, can read the electrical parameters (line voltage, current, active power, apparent power and power factor) of the socket through serial communication. The external jack adopts Japanese standard specifications, and the internal integrated single-circuit relay (AC-100~120V@10A) is used to control the power on and off of the socket. With the ATOM main control integrated with WiFi module, the power socket can be easily connected to the network for remote control And energy metering. The extra socket integrates HY2.0-4P interface, which can interact with external equipment (relay signal input, key signal output).

    Nice replacement for third party AC power controllers

    My needs were quite simple , being able to toggle power on and off from a rasp pi python app. Using MQTT this was easily accomplished. I am not using the v/a monitoring at this time. Bought two more for future tasks.

    Great Device need more documentation/Arduino support

    a lot of hardware is not supported by arduino by default or libraries don't exists would love to see more community work. i love the hardware you sell but more support of the chipsets would be great.

    It is a good product, though I would not recommend it for beginners.

    It is a useful product to keep track of power consumption, although it is up to the user to create their own firmware. Be careful when creating the application, as the buttons may work unexpectedly due to GPIO39 issues.
