Controlling WeMo switch...
Posted: Mon Aug 03, 2015 10:29 pmI'm very excited to finally be able to control my wemo switches with the esp8266. Below is the code I used for. It is just a simple example, need to add a button and filter the response from the switch to check the wemo status. ar
Hoping to hear some feedback and improvements from you guys.
