MILIGHT app, only 4 groups.

Hi there, how are you guys?

I recently have bought some milight bulb with the internet receiver and it worked great.
I have the bulbs conected to mi phone, but i have a lot of these lights and only 4 groups…

Do you know if there is an app or a way to have more groups?

I was thinking on buying another wifi reciever but i think there must be a smarter/cheaper way to do so.

Also if you have an app that programe the control the lights i would very appreciate. Imagine you could turn on/off at certain hours, etc.

Thanks a lot indeed!
