Making a WiFi Space Heater Controller | Custom Smart Plug

In this tutorial, I'm making a space heater controller that uses a WiFi connection to get Ecobee temperature data. Using these data, I can turn the heater on and off. It's basically a thermostat for the space heater. It's also a custom smart plug.
This video will provide instruction on how to use an API and make requests with Arduino, how to deserialize JSON in Arduino, how to create a local web server, how to access flash memory, how to control a relay, and other stuff.
This is a specific application of those various skills, but there's an endless amount of projects you could come up with based on them.
