Controlling CTLite G4

[Connaissance]

Does anyone know how I could control my CTLite G4 120W? (approx 22 by 26 cm) i.e. to dim and adjust colors.
I have 3 Slave units, so I can only turn them full on.
I've searched for a Master unit, but there are none for sale

Are you not able to use of the three as the master unit to control the other two?
Are you using the app on your cellphone?
