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

Oddly they don't list a G4.
There are contact numbers/mail/chat.

Thank you, oreo54!
These lights are several years old and aren't manufactured anymore.
I have contacted them by email, but they aren't answering.

Yea not surprising.
They don't seem like they were very popular around " here". Think you got quite the challenge. Is the phone app even available? Will it work with the current versions of the OS?

Out of curiosity do the lights work at all w/ out the " master"?
Or possibly just full on when plugged in?

I've got reply from CTLite now. They said it was discontinued 5 years ago and that were nothing they can do to help me. Told me to buy their new ones.
 
I recently got hold of a CTLite G4 Mega Aqua Master unit, but unfortunately it’s not broadcasting any WiFi signal (neither in AP nor Station mode), and I can’t connect to it via the app.


The unit powers up and blinks like it’s trying to pair, so the LEDs seem to work, but there’s no way to access the settings or pair it with anything. I’ve tried powering it off/on, waiting several minutes, and checking for hidden SSIDs – nothing.


Has anyone else had this issue with the G4 Master version?
Is there any known method to reset it, force it into AP mode, or re-flash the WiFi module?
