I want to setup a single float switch in my ATO reservoir so that when it's low on water it can send me an alert on my phone (via SMS/text/email... something) and turn off a certain relay socket (keep the pump from running when there is no water).
Is this covered in the wizard or will I need to do some research and write this code myself?
And finally, regarding the single float switch... I've looked at the user manual and can not determine how to position a single float switch for proper operation. Do I want the threads/nut side of the switch UP (fig A below) or DOWN (fig B below)?

Thanks
