This is some fantastic stuff that you're doing and I really hope you continue to develop it.
I had a bit of trouble with the code that your creator made. It didn't seem to work, I couldn't get my Android to sync.
When I used that simpler light one that you posted on the 2nd or 3rd page that worked well. At least, I could switch the light on but not off.
The Android app is a little buggy and needs some work but it's a solid start. I've had a little bit of experience with electronics, I'm an avid Arduino user and a beginner with the programming. Keep up the good work, this will be a great project to follow.
Thanks.
