Hi ,  
I am using esp8266 to run my program led example. I extended it for my needs. When I am trying to add more than about 8 led things or when im clicking on thing board, device (esp) reboots.  
Should I do it in a different way than shown in the program (led\_example) when I want to add more devices (led)?

You’ll probably want to increase the size of your JSON buffers, which you can do with 0.11.X versions of the library. See [here](https://github.com/mozilla-iot/webthing-arduino/blob/master/README.md#configuration) for instructions.
