I'm sure its great, if you can get it to work.
Upon installation, device launches, and starts with control tab:
'No JSON decoder'

Color wheel tab:
'The plugin is not configured. Please go to the 'Settings' tab.'

Ahh, perfect. Lets head over to Settings:
'There has been a communication problem.
Please try to reopen this tab.
}'

I assumed this error may mean it cant find my RGBW controller, which is a problem, because I have a FGRGBWM-441, included and working.
Didn't see any place to send a question, or review documentation. With that, great concept, if it worked.
