. I'm not sure what HA Dave is referring to re the CM15A perhaps the IR543-PLC will trigger CM15A macros.
Yep. We can do so much more with a macro than just a light on or off. I use the Logitech Harmony remote with my Theater... which sends the X10 IR signal to the IR543. The IR543 sends the PLC which the CM15A interprets as a macro trigger, to setup the lighting (and other actions).
My only concern.... after some serious thought... is how many voice commands are available. And I wonder if a call to tech-support might help find/explore/create all the choices.
I am a big fan of the Logitech Harmony remotes. I've used them in theater installs... and even have one on my living TV. I can also use my phone to control TV's, and streaming units (apple, and Roku). But the Logitech Harmony remotes are very well designed/made.
It was my Home Theater that got me to X10. I built the theater more than a decade ago.... and it has had several updates. But
I've kept the old incandescence lighting in the theater. Because it works (and is X10 controlled)... and because the lighting gets so very little use. Converting to LED lighting would take more years to recover any saving..... than I have years left.
I am controlling some LED's elsewhere using SocketRockets and/or the "clicking" appliance modules. But there are also some parts of my X10 setup that uses Universal modules and the alarm modules (as well as sirens and chimes). That just wouldn't not be all that easy to rebuilt/replace with other HA products.
But that is where I am at. Trying to figure what part of my X10 I can control with Alexa...... or continue to control with alternate methods. And what I may want to modernize... now or later... to one of the (now) many flavors available.
I am truly enjoying the building, and rebuilding, of my setup....
in my imagination. I haven't worked out all my choices yet. And I am really enjoying reading of others progress. There are a lot of bright, imaginative, and knowledgeable people here at the X10 forum. Many.... although no longer with us... continue to educate and inform us from the record of their posts.
