No separate microcontroller required at all. Just install the two drivers, as described in the ReadMe, then create a virtual device using the Harmony Hub Parent device. Configure the settings of the Parent device, click save, and it will handle the rest for you. All of your Harmony Hub Activities will be created on Hubitat as child switch devices.
This integration use a webSockets integration directly to the Harmony hub. Thus, it is important that your Harmony hub’s IP address does not change. Reserve an IP address for it using your router’s DHCP server.
