Checkout NodeMCU. You can program in lua. There are some downsides, but overall my experience with NodeMCU is fairly good. Just like everyone else, I've been using them to upload sensor data (humidity, temperature, strain).
Tips: The cpu is responsible for everything, so if you crash it or get it into a loop the serial output will stop. Be careful with what you put in the init.lua, since it will run on startup. If you do get stuck in a boot loop simply hold down the button while pressing reset, and it will get into a recovery mode. Then use the nodemcu-flasher to reflash the chip.
