Bluetooth Connection

I’m wondering if the device the Turntouch is paired to has to be “on” all the time for the Turntouch to work? I know that once I paired it with my iMac when the iMac went to sleep it would no longer work my hue lights. I was hoping to use this independently of the device it’s paired with.

Yes the device has to be on. For a Mac, the Mac has to be awake. For an iPad or iPhone, the app will wake up automatically when a button is pushed, but the device itself needs to be on and have bluetooth enabled.
