I am pleased to announce a Release of my new Logitech Harmony Hub Driver. This driver communicates directly to your Harmony Hub over your LAN. It will create a child switch device for each of your Harmony Activities, and will keep them all up to date with instant status updates from the Harmony Hub. No polling required!
This integration requires new LAN connectivity features only available in the recent Hubitat Elevation Firmware version 2.03.
The instructions for using this driver are available in my GitHub repository within the ReadMe for this driver. This is a very early release. I expect users will want enhancements. I encourage GitHub Pull Requests as I welcome community support of this integration!
