If your pill box does not make any noise or none of the lights turn on, it could be possible that the battery became disconnected. One big drop or a few small drops could result in the battery unplugging.
To resolve this, let's test if EllieGrid works when it is unplugged. One way to test is to plug it in to charge and then push the pinhole reset button to trigger the blinking reset light. After unplugging the cable, the lights should continue to blink.
If the light stops blinking, please email us at firstname.lastname@example.org so that we can further resolve this issue for you.
