A take on the classic https://computerpowertest.blogspot.ca/
A wall-mounted light-up display that alerts you whether or not your WiFi is live. This will utilize the ESP8266 to poll your home network.
Other features include:
- displays wifi network name and password upon request (allow company to access your network)
- fetch and display your network download and upload speeds
I don't know how I've lived this long without it.
