From 2000 through 2015 I had my whole house working with X10 devices including 3 Dimming Wall Switches. 10 lamp modules, 5 Appliance Modules, Door Chime, 2 cameras, controller module, Transceivers, multiple remotes and 4 Motion Detectors. I had a Smarthome Signal Repeater plugged into my 220 volt dryer outlet to allow the X10 signals to work across both phases of my 220. I had macros controlling lights and appliances.
Then the Smarthome Signal Repeater quit working and X10 devices on one phase stopped working since the controller signals would not pass from one phase to another.
After doing some research on the different smart automation schemes I changed everything to Lutron Caseta in 2018 and 2019. I now have Lutron Caseta 6 Dimming Wall Switches, 3 on/off switches, 5 plug in lamp modules, 8 pico remotes, and the smart hub.
Lutron Caseta switches cost more but they have the following advantages:
1) The dimming wall switches do not require a neutral. Like many homes most of my wall switches do not contain a neutral.
2) The on/off wall switches can be used with existing 3 way switches.
3) The quality of the Switches is much better than the X10.
4) Most important is the Lutron Caseta Smart Hub integrates with Alexa, Google, and Apple Home Kit (Siri). Thus I can control all of my lights using Alexa or Google (My Dish Hopper3 has Google Assistant built in) or with Siri on my Apple IPhone.
5) I have created Scenes and Schedules on the Lutron Caseta hub to control lights based on x minutes before sunset and based on occupancy.
6) On Alexa I have created Scenes such as "Night Light" to turn on Main Bedroom and Bathroom Lights to 10% for nighttime bathroom breaks. Movie Light dims Living Room Lights for TV watching.
7) Unlike X10, the Lights turn on to the set brightness. X10 would turn on at 100% and then go to the preset brightness.
8) You can program a preset brightness for the center button on the Pica remotes and wall switches.
9) The lights can be CFL, incandescent, or LED.
10) I can control all of the Caseta devices remotely through my Apple TV.
11) Caseta will also control Serena Shades and several thermostats.
