# General info

There are two Hubitat Hubs. One is a C8 Pro on my desk and one is a C7 in the furnace room in Mike's garage. Both are powered by USB. The C8 Pro is USB-C and the C7 is Micro-USB

The C8 Pro is "home" to most of the devices and rules than run the smart devices around. It is also attached to Home Assistant through a Make API app called Home assistant. you can access that app [HERE](http://10.100.100.21/installedapp/configure/232/mainPage "Home Asssitant app in Hubitat"). Please see the [Hubitat Rules](http://wiki.blizzhome.com/books/smart-home/chapter/rules "Rules") chapter for configuration info.

The C7 has a couple of devices on it but it is primarily for the Zigbee "911" buttons throughtout Mike's House. Those rules are on the C8 Pro hub and can be found [HERE](http://10.100.100.21/installedapp/configure/2092/mainPage "Bedroom Button"), [HERE](http://10.100.100.21/installedapp/configure/2109/mainPage "Garage Button"), and [HERE](http://10.100.100.21/installedapp/configure/2107/mainPage "Living Room Button").

The two hubs are connected together through the built in Hub Mesh application. This app allows sharing of devices between hubs. [Hub Mesh Link](http://10.100.100.21/device/hubMesh)

Both hubs will look similar to this. The C8 Pro has external antennas.
