The ESPs while technically not a Hub do bridge the connection to all the windows and door sensors that are hardwired in my house. One set acts as my [DIY alarm system](http://www.vmwareinfo.com/2017/06/building-my-home-alarm-system-hardware.html) while the other act as [DIY Motion Sensors](http://www.vmwareinfo.com/2017/11/yet-another-inexpensive-motion-sensor.html). The Aura system uses Wifi waves to detect motion through walls. It covers the entire house. Scenes are activated via IFTTT/HA integration.
