I have built many smart home devices and used full size ESP8266 until I found this one. They work the same as my ESP8266 but they are smaller and we are exactly what I was looking for. They work with my ESP8266 code, except instead of NodeMCU 12e I just chose Wemos D1 Mini as board type. I love that they come with many different headers, as some headers are better for prototyping and others are more permanent solutions. Nice to choose. The price of about $5 per board is perfect for my projects.
