I’m thinking the CM19a and a plug in transceiver to cover rf and pl might be the way forward X10 hardware wise. Probably the Raspberry Pi Zero WH to keep the footprint as small as possible.
If anyone has other suggestions just fire away.
Now all we need is to agree on is the software platform to run all this. Plenty to choose from so any suggestions more than welcome.
The CM15 is my current choice to run with the PI the PI zero W even fits inside the cm15.
Of course if the CM15 was to get an overhaul with better PLC and RF it would I suspect be everyone's choice.
As for software I believe user here mostly want easy to setup without having to search for extra drivers and play around with for days on end to get simple HA control.
Get a "WORKING" set-up! Something that we can use..... not a new hobby we can take-up in the middle of yard-work season. Just... MHO.
I've had a simple "WORKING" X10 setup running well now for several months.
I originally figured from reading your and others exploits that this would be just a hobby to play with on rainy days.
This was not the case with HomeGenie simple x10 control was up and running in less time then it took to write a SD card.
Adding macros and timers too were a simple add. Customized things with adding Alexa control, security, and special Camera macros took a bit longer but no longer then my special AHP macros. all my HA needs are now off the PC and running on a PI and CM15
I've tried a few other Linux softwares and although they may be more actively being developed they are not as easy to get working for X10 (just my lack of linux experiance mostly).
I'd like to keep this subject as positive as possible.
I'm only too aware that a certain cohort would not give Linux or its variants the time pf day for whatever reasons, good or bad. I respect that. I wasn't aiming this post at them as can be seen from the title of the post.
The Pi unit is at the end of the day an educational board that has evolved far beyond its original purpose. Contrary to some beliefs it is not going away and has in fact renergised interest in a market that is flooded with smart phones and smart tablets with little or no access to their working parts and very little chance of the ordinary man or woman in the street learning anything about their inner workings.
Regarding a working set up, it's there. It's working and believe it or not it has does have Microsoft related "bits" inside it too. The problem is because it doesn't have a large price tag attached there must be something wrong with it.
In fact for those who are not aware of it, there's a unit called a Hometroller from a company called Homeseer. This unit is a fairly low speced, in today's terms, Raspberry Pi in a case complete with their company logo with an older scaled down version of the company's automation software with limitations on what plugins can be used. Price tagged at $199.95. Interestingly there could be one or two users who actually own and run one on this forum. And yes its run by the dreaded Linux OS Raspbian. This system is no different from the one myself and Tuicemen are suggesting.
For all the time, attention and dedication given to the WM100 I'd hardly call it a working solution either. In fact I'd attach it to the other end of the handle of my yard brush so I could lean on it in between brushing sessions
