Aoycocr-X10S Power Monitoring Plug

Aoycocr-X10S Power Monitoring Plug

Device Type: plug
Electrical Standard: us
Board: esp8266

This device did not have a serial number. FCC-ID is 2AKBP. This device shares the FCC-ID with Kauf plugs and also Cloudfree smartplug 2

This template was based on the AWP04L template and modified for this device. I used a Kill-A-Watt meter to measure voltage, current and watts of the plug with and without a downstream device turned on. The downstream device was an LED bulb. Power Factor was .93 on the Kill-A-Watt meter

The GPIO pinout was learned from Blakadder Tasmota documentation.

Note: You will want to exclude the red_led and blue_led lights from your recorder component, especially if you use the included Throb custom animation, since that would fill your database with the on/off blinking status updates.

Split Configuration

If you have several of these plugs, you may prefer to keep the shared code in one file and only put the device-specific code in the files for each plug.
