I looked at many threads and could not find the answer.
The Koada project seemed perfect but has died off?

How would I be able to control a Mean Well HLG-240H-48AB or HLG-120H-48B?

The Kingbrite pre-assembled 120W quantum board seems to use include a potentiometer, is that the resistor way of controlling the dimmer?

The need is to simply turn it on or off, ideally through another program (wifi or raspberri pi).

With the research, it seems there is the Mean Well SPD-001 would configuring and plugging this in work?

Do you need remote dimming or just on/off?

Just on off, but set at the last dimmed state.

I'd use a Pi or Arduino in conjunction with an optocoupler like a PC817 to do PWM dimming and then have the Pi or Arduino also control an AC outlet via wifi or something that turns the light on and off.

Thanks, it looks like I'll go with a pi with a few WhiteBoxLab T3 Tentacles and run Mycodo.
Now to figure out how to emit that 10v PWM...

The driver emits 10V itself. You just need to switch it on and off with a transistor or optocoupler. You can do this with a 3.3V or 5V output on a microcontroller.
