Dingbatt:
I have an HTPC that runs 24/7. Can you give me an example of HA software that will run on a PC? Windows 7 actually, because I wanted to retain the Media Centre functionality.
What additional hardware is then required?
I ran OpenHAB and HABridge on a Windows 10 VM for a while (running as a Hyper-V) instance on my desktop. That worked fine. But it seemed overkill (and anyway I didn't have an activation code for the VM) so just moved it to a Pi3 which is fine also. It's just JavaScript after all.
