In these hectic times, a lot of us don't notice when our phones make a short beep.
But a phone call directly from the sensor will ensure a timely answer. You don't have to worry about noticing this warning. You can set the water sensor to call you within seconds after the first drop of water.
One of WLD2's main advantages is that it supports zone creation. And so the flood sensor can call a different phone number for each zone.
The zone where the flood occurred will be indicated in the SMS also.
In addition, this solution does not require SensDesk. All you need is an SMS GW3.
