truckdiagnostics - X-10 can be finicky on transmitting its signals, especially if there are multiple panels, noise on the line (yes some power supplies cause this) or an additional transformer.... although not as price friendly you could look at Pulseworx which uses UPB technology to communicate over the electrical wire. They have a Split Phase Repeaters & Split Phase Couplers to overcome such issues & should be able to overcome the transformer issue. They also have a module allowing X-10 signals to communicate to & from their devices so you can mix & match..
I did a lot of X-10 back in the day (started 20+ yrs ago), still have a bunch of it on my shelves, for lighting control am currently certified for Pulseworx, Lutron (Ra, Ra2, Homeworks), Vantage & Centralite lighting control systems & the one thing I can say about X-10 is either you have great results with it (like industrial Toys) or you are chasing demons... Pulseworx just works better... if there is an issue they have the work around. I have residential sites that have over 220 controlled loads in multiple building & if designed correctly work flawlessly... Just another option for UPB lighting...
For control options you could also look at Global Cashe & Control By Web they both offer very reliable hardware with Web Interfaces built-in (not inexpensive but very reliable).
I have a Dakota Alerts MURS system (we are also dealers for) with 2 probes in our driveway (little over a 1/2 mile long) which work great, zero false alerts. I use their base stations N/O contact relay to signal our ELANg home automation system, then based on events / status / time of day, I can trigger different events such as lighting, email notifications, camera snapshots ect....
