In Part 1, half the space is taken up by the IoT power supply. Here, in Part 2, is a proper 1-gang IoT AC mains power extension using the ESP8266 NodeMCU ESP-01S and a very handy 700mA 5V AC mains power supply.

|Assembly is straightforward. The power socket fits nicely over the power module and the ESP-01S relay modle without coming into contact. Note the cable ties to hold the modules in place|
You may need to drill a hole in the side for the power cord, and maybe enlarge the various holes in the bottom enclosure to fit your cable ties.
