Control Appliances with Avatto Wi-Fi Wall Socket via HTTP Requests

Avatto Wi-Fi wall socket is 16 A wall socket that has two USB ports and integrated ESP8266 Wi-Fi module. This socket is compatible with Tuya Smart mobile application that allows to remotely turn on and off appliances.

Many device vendors uses Tuya firmware and cloud services.Tuya doesn't provide a way to control devices locally without connecting to cloud servers. So I decided to use Tuya-convert tool to flash Tasmota latest firmware to Avatto Wi-Fi wall socket. After it finished, I connected to Tasmota dashboard using a web browser. I started to create device template. I tried to assign the components to the GPIOs to match wall socket. After many attempts, I found which GPIOs are responsible for controlling the socket components. Here is a template:

{"NAME":"Avatto Wall Socket MC-801","GPIO":[0,0,0,0,576,32,0,0,0,0,224,0,225,0],"FLAG":0,"BASE":18}

The following image shows components of Avatto Wi-Fi wall socket (MC-801 model):

Wall socket can be bought from AliExpress.

The following table presents how components was assigned in the device template to the GPIOs:

Tasmota has commands can be issued using HTTP requests. We can send HTTP GET requests to control relay 1 and 2 to turn on and off socket and USB ports. The following table shows commands:

We can provide one of the following parameters to the command:

If command is used without a parameter then current state is returned.

The following table shows examples of HTTP GET requests using curl command:

• IP_ADDRESS - IP address of Avatto Wi-Fi wall socket.
• Command Power1 can be replaced with Power2 to control relay 2 or Power0 to control both relays.

We can send GET requests programmatically. You can read post how to do that using various programming languages.
