Sorry for the noob question, but after I set up a new pulsegrow-pro, I wanted to turn it off and let it fully charge. I tried holding down the button for 3, 5, 10, and 25 seconds, and afterward my cell phone app was still reading the sensors. I looked around, and I found an online suggestion that I should be able to turn it off inside the (Android) native app, or in the web app via the device settings. When I looked under settings, I did not find any buttons, etc., suggesting I could turn it off. I have since unplugged it, and it is still running. I figure that there is some magic Vulcan death-grip to cause the unit to shut down while still charging the batteries.
Thanks.
