In this tutorial I will show you how to convert an old power strip into WIFI remote control.
This will allow us to control electrical devices from the Internet via HTTP. For example we will
be able to turn on and turn off a heater, fan or light over the internet. To build i will
use a popular electronic circuit ESP8266 D1 mini. ESP8266 is a good platform for iot (the Internet of things).
At the beginning I removed the broken switch and everything cleaned.
Step 3: Measuring and cutting
I measured and cut the plexiglass board for electronic circuits.
For cutting I used Hot wire foam cutter from the previous project.
Follow this link to see how I built this tool.
Step 4: Drilling
I drilled mounting holes, for plexiglass board. Then I mounted the plexiglass board inside the power strip.
Step 5: Scheme
Step 6: Mounting the plexiglass board
The next step is assembling the plexiglass board and electronic circuits together. In this project, I only use one relay to control power strip.
Step 7: Mounting ESP8266
Because my power strip is made of metal, I'm afraid there might be a problem with the WIFI connection.
That's why the ESP8266 is assembled inside a plastic case and screwed to the power strip.
Step 8: ESP8266 flashing firmware
I had a problem with flashing firmware. My version of the ESP8266 D1 mini has something wrong
with the RST pin, it does not work. That's why, I disconnect the USB cable from the computer
instead of using the RST button. In this article, step by step, I described the entire software flashing procedure. SONOFF - ESP8266 update firmware with Arduino IDE
