''During our research, we found a million different leak sensors. However, most of those didn’t have “smart” features. A good smart water sensor is compact and will alert your smartphone or tablet whenever water is present. And it delivers those mobile alerts regardless of if you’re inside the house or on the other side of the world. When you factor in the smart aspects, the list of what’s out there is much smaller—but still too lengthy for our mission. So we narrowed the list using price, features, and availability. Also, we were specifically looking for smart leak sensors that you could easily install yourself. That narrowed our list down to seven products to submit to our water-torture tests.''

Brings me right back to what exactly constitures a 'Server.'

I'v reviewed the Nunchi patent and brought it here to us, it states a 'network server.'

''A server is a computer that provides data to other computers. It may serve data to systems on a local area network (LAN) or a wide area network (WAN) over the Internet. Many types of servers exist, including web servers, mail servers, and file servers. Each type runs software specific to the purpose of the server.''

IMO YOUR HOME WIFI COULD BE DEAMED A SERVER.

When I graduated CS in 1990 LAN = Large Area Network, now it's 'Local' ie your HUB.
