... An Authinx created/supported application running on an Authinx supplied RPi3b that basically replaces AHP and supports all the above might be useful to those not ready for (or not needing) the WM100. And, it would give Authinx another product to sell.
I am in complete agreement! You had this idea LONG before I became aware of Raspberry Pi. But in recent months... I have learned my lesson. Now, I've been working on a Raspberry Pi 3 solution myself. Unfortunately... so far I have failed. But others claim various levels of success.
[Of course... Thanks to
fernracer I own and use one of the Homeseer Hometrollers...
which is a raspberry Pi running HS proprietary software. And it's an amazing setup... which uses the CM15A as an interface.]
So I KNOW a RPi3 solution could be perfect. Of course with the current reconfigured AHP (download).... maybe on a PC stick might be just as functional with a CM15A. Either with IFTTT could make Google Home or an Amazon Echo effective.
I would think... if someone would even just master a setup for a Raspberry Pi and image the whole thing on a SD card... there would be a market for those. At least... I would hope so. It would be an elegant solution. But if X10 was to enter the market... the Raspberry Pi could communicate with the WM100... and not need to bother with a CM15A for an interface.
