Hello!  Purchased a Pixie from Amazon.  Easily set up the device, charged the battery, connected to the outdoor faucet, but the valve won't open.  I tried both through the app and using the 2-push manual button.  Both changed the light to blue, but no water came out.  A click could be heard though.
	
	The tap was most certainly on.  Is there a solve for this or did I just get a bad lot?
	
	Thanks,
