FireTV Stick Power On/Off w CEC

Has anyone successfully set up a firetv stick to turn the vava projector on/off with the firetv remote’s power button? I am able to control other TV’s using CEC but vava doesn’t show up in the list of brands to control. Anyone know a brand that would be compatible?

I have the same problem with Apple TV. Anyone know how to set up the projector so that it powers on/off with Apple TV waking up and going to sleep. This works wonderfully with my Sony TV and Apple TV via HDMI

I have same problem. I think VAVA CEC has problem.
I am using fire qube 2g tv and apply 4k tv box it’s not working.

I can only turn the projector on with the fire cube, cannot turn it off.
