I used to use the X-10 system. But that is old technology even though I never had any issues with it. Sometimes I need to control security lights that I can not install a wall switch for.
I will look into the ZigBee technology.
Thank you for your replies.
Lol,
My introduction to Home Automation/Control started prior to X10 in the EARLY 70's. I built my own system using a Sinclair 1000 computer (and still have in the original box with the 16K plug in module) even before I got my Commodore 20, then 64 (which I also have yet). All the modules were built from scratch by me and were connected to a relays that controlled the lights. Used low voltage, Quad telephone wire and a lot of relays. Was happy to see X10 when it was introduced, even though I had to un-wire everything.
I then saw and purchased my first X10 back in the late 70's and have made a few transitions since then (all those went belly up). The X10 program was running on my Commodore 64 computer. The only issue I had with X10 was line noise and I used capacitors across each phase and neutral to eliminate MOST of the line noise issue. I always issued commands 2 times to insure that the proper request was received by the X10 module. I still have a box of about 30+ X10 modules and devices that all work.
I am now in the process of moving my Home Automation/Control devices/sensors to ZigBee with some Z-Wave and away from Insteon products. Currently my home is controlled by Insteon (they went belly up this year) sensors and modules and the main controller is "POLISY" by Universal-Devices. I love POLISY (so does the wife) but I have started moving away from it to "Home Assistant", which is an "Open Source" system that communicates with almost EVERY type of manufactured module/sensor. They do have their own HUB/Controller (optional), but you can load the "Open Source" software on a Raspberry Pi, which is the method I use (Raspberry Pi 4). For residential customers I would most likely go with the "Control4" system which of course is expensive $$$$ and again is a propitiatory system, but it is high end and has a GREAT user interface and features. You need to complete a training process to be able to purchase/install their products.
You know that your Home Automation/Control system is designed/working GREAT when your neighbors call you and say they thought you were on vacation, but they see the lights inside and outside the house are going on/off at random times along with shades automatically opening/closing depending on TOD and sun intensity.
Currently I am working on an electronic "big mean barking dog" playback system. When there is someone that gets withing 15/20 feet of the house's perimeter. Two large speakers inside at different sides of the house that will adjust the speaker volume to sound like the dog is running back and forth and if they go to a door there will be a speaker behind it to sound like the mean dog is right behind the door. Probably a hundred watt amp will be needed. Working with Laser and Ultrasonic sensors to detect people walking close to the house.
Personally, ZigBee is the way to go. Z-Wave is OK, but has a Z-Wave alliance and is part of the I think it is called the "MAKE" alliance which Microsoft, Google.... and other BIG names are pushing which means you will need a "MAKE" hub ($$$$) and only use MAKE specific Z-Wave products ($$$$). MAKE is still in the planning stages as it has been for the last 4 or so years.
Good Luck
