Reading here I'm encouraged by the PiX10 threads. This could be what I need to extend the life of my remaining X10 switches..... Not sure about Google home integration there, I'll have to keep reading.
You sound (read)
much like myself. How could (as automation guys) we ever past up things like Nest, MyQ (garage door control), and AI devices... like Google and Amazons. RIGHT?!?!?
But
not everyone here thinks like we do. Sure we want to keep X10 up and running along with our other whizzbang new stuff
why wouldn't we. And the cloud operated devices are the perfect integrator of everything. Except of course X10. Because X10 doesn't offer a Hub.
I've integrated my X10 with Amazons Alexa... using a Homeseer S2 Hometroller. You might be able to do some of the same using your Logitech Harmony Hub (maybe using a IR-543 X10 Command Console).
I was sadly disappointed when X10 didn't make their WM-100 an Internet Hub. And from what I am reading about the Pi X10 Hub.... it seems to be more Home Genie centric than Internet appliance.
The old X10 smart home with a (cm11) or CM15A (AHP Pro) connected to an on-line computer running various software(s) (and connected to others using a peer connection) seems to be an old idea.... still stuck in the minds of many. IMHO.... there is little to
absolutely no reason to try to whip centralized computing power out of an Internet appliance.... when that is what the cloud is for. After all... it works flawlessly with our garage door(s), thermostats, and myriad of other automation devices.
But
not everyone thinks like us.... or trusts the Internet, or google, or Amazon, or capitalism or whatever. And exploiting Internet technologies isn't an idea they like.
