In order to use Iris you need to have broadband internet in your home. You also need to have a router with at least one open port. Once you have your Iris hub it will connect to the internet via your router using an Ethernet cable. Please note the Iris hub will not connect to the internet wirelessly.
There are a handful of devices that do not require an Iris hub to connect to your Iris account. Each of these has built in Wi-Fi that allows them to talk to the internet via a wireless network. These devices include:

Whirlpool 46000 Grain Water Softener (Item #632879)
