First of all I want to thank you for creating SUPLA.
I think SUPLA has high potential to be the best IoT platform but I don't now why I can't find some project for it!
For example if I search for "arduino Esp8266 thingspeak" I find a tons of sample project but unfortunately seraching for "SUPLA esp8266" gives me only a sets of youtube video,nothing more!
There are a lot of users that can use SUPLA with Arduino and I think if you can prepare arduino IDE sketch for esp8266 your IoT platform can have more and more users But unfortunately you only made arduino mega library for arduino users,when we can use a 2$ module why we must buy arduino mega????
