Sounds like your interested in X10 or zwave to control switches.
I've used X10 in the old house.
In our new place, we had about 25 new LED (recessed) lighting added. To simplify things and to get through permit approvals I did everything with traditional switches.
Over the winter I will try switching out to Zwave.
Since its done at the switch, its not really too big of an extra expensive (not having done it at the start) as there are really only 3 or 4 LED switches to be updated. I'll also be swapping out a few traditional switches, which were already existing.
Anyway.... X10 sends signal over the wire. Decades of successful use.
Zwave is newer and sends signals via RF. a few advantages I see are:
- there is a multiple signal acknowledgement back and forth to make sure there are no erroneous switching. I had a problem with this using X10, but in another thread others jumped on me saying they never had a problem
- Being RF it can send signals to battery operated devices directly... such as a thermostate or digital door lock. When we got a digital lock for the new house I paid the extra $40 to get the zwave. I believe I was told that X10 now has a wireless component.
- - Battery operated security switches... windows.
Check out:
Z-Wave : Home control
Google X10
and make sure they both support the devices you'd want to control.
lastly... more specific to your question... When googling LED lighting it seems no matter the scenario people have bumped into problems with dimmer switches. I've had no problems, but I do have a concern, and some research to do.. regarding what switches are best for zwave.
