I want to replace my X-10 dimmer switches. Since they are in my media room, I want to control them with my URC MX-450 universal remote, as I do now. It can do IR or RF. There are 3 switches to replace. I also want to use them manually sometimes. Suggestions?
RF? Do you know which standard? Does your remote control x-10 directly?
IR seems harder to come by in recent years. I still see a few via google search. You would have to determine if you could teach your remote the proper codes.
I notice that, at one point at least, lutron made switches that can be controlled directly via RF and the MX-450. Whether they still do, I cannot say, but my suspicion is that these are not.
Much could depend on what it is worth to you, both time and treasure. I have a home automation hub that can learn IR commands and react to those commands as programmed. It can control insteon and z-wave switches. this would be an investment of hundreds of dollars and hours of time for you to learn how to set it up and program. It would certainly be cheaper (and likely take less time) to replace the remote with something like a Harmony Hub and compatible switches for your lighting.
Most X10 model wall switch dimmers where two wire Line and Load. With the switch getting power through the load. I would think most modern automation switches would also use the Neutral connection to get their power. Check to see if there are neutral wires in the back of the switch box. So you know if it would be part of the equation.
