I be able to copy the set up via software (with PC Access?)
I do not know. That said I keep both a drawing and hand typed over view summary of what is is I have done and used.
I consider the Leviton OmniPro panel first for security then secondarily for automation (basic stuff that just works).
The Leviton panel that I consider an automation controller on steroids is just that; very simple.
No bells and whistles; just an automation controller.
The computer chip and software in firmware on the OPII panel is very basic. That is where you look to integrate the combination security / automation panel to software. I can here shut off the automation software and the panel will turn on an off lights, connect to my HVAC thermostat, talk to the Omnitouch screens, do video CCTV, do Russound audio et al.
I do not and never have had automation dependencies on my multimedia. That said I can get to my Russound zoned amplifier from Russound keypads, Homeseer touchscreens or Omnitouch screens. I integrate my touch screen clients to the zoned amp and multimedia and do use it but not dependant on it.
Utilize Kodi boxes today as STBs, NAS boxes for internal multimedia, et al. I do not watch television but have had broadband, OTA, Dish and DTV all at the same time for a choice.
I know nothing about OpenRemote. With software you can do any type of integration (literally) to your Leviton HAI Omni panel.
I do have energy watching on some Z-Wave and Zigbee stuff; but never have watched or cared much about this.
I mentioned Homeseer because I have used it since the late 1990's.
You do have a nice choice today of software integration to the Leviton OmniPro panel.
Have a look here on Cocoontech for all of the options available today software wise for Omni Integration.
