This article explains how to extend a Korad KA3005P power supply to be able to manage it thru your Wifi network with a simple Web browser.
Thanks to an ESP8266 module running a modified version of Tasmota, the KA3005P will get wifi connectivity. The power supply then becomes fully connected and can be managed thru a smartphone, any computer connected to the same network or even thru a MQTT client.
The ESP8266 will act as a bridge between the power supply serial interface and your network. It will provide a complete management console with real time display.
All you'll need is :
- an ESP8266 module
- some basic electronic components
- an USB to serial interface to program the ESP module
This hack is based on a Korad KA3005P, but it should work with other Korad power supplies providing a serial interface.
