All you need is a Windows computer that is:
1) Always on, and
2) Has a WIRED connection to the home WiFi network.
Once you have a hard-wired connection to the internet, the unGlue Home Monitor and unGlue Parent App should pair correctly.
If you don't have a home computer that you can always leave on, our unGlue Puck is a small device that attaches to your home router. The unGlue Puck costs $39 and can be purchased in the Parent App once you begin setting up the unGlue Home Monitor.
