The ESP8266 is an amazing little processor: cheap and capable and (most interestingly) WiFi enabled. I have some of the older “nodemcu” boards that I got for about $7 each, but there are newer alternatives that include up to 4M of flash memory, and a variety of interesting form factors.

I noticed that WeMos was producing these boards which nominally have the Arduino Uno form factor. With a 15% discount coupon from banggood.com, I got three of them on order for under $16. I’ll let you know how they work out. I’m normally not a fan of the classic Arduino shape, but I do have a number of 3d printed cases and bumpers that can be used, which makes them relatively easy to mount and wire up.

If you want to program the ESP8266, you might try using platformio, which makes it easy to use both the native SDK as well as a simpler Arduino based framework. It also supports a number of other embedded architectures, including the Arduino, but allows you to use your own editor and the like to build and organize your code. Worth looking at.
