.........if you were looking for a new HA software, what would you use? ....
Sorry to read about your HomeGenie setup. I think the greatest fear of any HA user.... is losing our systems due to some failure that is out of our control.
I think (just my own humble opinion) the AHP software with the CM15A interface... was at one time... heads and shoulders above everything else.
Running AHP (and a few plug-ins) along with BVC (Bill's Voice Commander) on my Home Automation XP PC (running 24/7).... was pretty high tech.
But that all started a decade ago. But... also I have two back-up desk-top PC's loaded with AHP, and one additional laptop in case my current laptop fails. And thankfully
Tuicemen has created a means to continue with AHP.... maybe for years to come.
I keep hoping X10 will introduce a new wifi interface with new abilities that build on the old AHP. But I am not holding my breath either.
The grandkids crushed my daily-use laptop a few weeks ago. I have a Home Theater electrically operated recliner I use as an easy-chair now. And they accidently got my laptop caught in the mechanism while they played with raising and lowering the footrest. It was an old windows 8 laptop that had upgraded to the windows 10 OS.
In a way.... much like yourself (and HomeGenie) I first wondered... what should I do now? Which technology should exploit? I've played with android tablets. My wife has a iPad she really likes. I could got a windows tablet or a surface unit. I have an iPhone and an apple TV unit.... I could use a Bluetooth keyboard and mouse and use my phone and TV as Hi-tech Internet device.
I bought a new laptop. It was just simpler not to have to think about it.
And that may explain why many of us here continue to wait for a new X10 interface. Although many of us have also experimented with other devices and interfaces too. I've often wondered why I am using AHP/PC timers..... when all that stuff probability should be converted over to cloud-based AI stuff. After all [Amazon's] echo is currently the heart of my system. And why am I running my old XP laptop 24/7 when I could likely get similar results running everything on my phone (which is already running 24/7).
After all... all the best setups of a decade ago... resembled AI in they're operation... if only by using multiple simple macros. Today much of that AI technology is already there. I regularly talk to Alexa, telling her [it] to remind me, set an alarm, give me info on a actor, or something. Although control of my X10 is now accomplished using a Homeseer device... that works flawlessly with my CM15A and Alexa.
So that's my rambling advice. Find a copy of HomeGenie (if that's what you NEED).... but migrate over to voice controlled, phone monitored, cloud based AI technologies. And.... wait for the new X10 interface with the rest of us
