Yes, we have used this method and to be honest found it MUCH easier than the Arduino with ESP shield method.
We are BIG fans of the WeMos, reliable, cheap and easy to set up.
You can attach dozens of sensors to a WeMos, including the mini's, with less cost and effort than messing about with Arduino's. Think long and hard before using an Arduino on an IOT project.
Don't even think about ESP01's unless you are using hundreds of them or are unable to redesign your project for anything bigger to fit. Proper ESP's cost about the same as the near useless ESP01's these days.
