im looking for this too, since i actually don't have a timer to switch on/off the lights. Seeing my friend turning the knob every morning on his 2FT tank seems a hassle compared to on/off with just a small metal knob.

You should get a timer for your lights to save the hassle.
If you want to automate your CO2 on/off, then you can get a solenoid like in the picture. It connects to your timer so it turns on/off on schedule.

Anyway, I haven't got a solenoid. I slowly adjust the Co2 bubble to a comfortable level and leave it there running 24hrs.
