Well X10 did an OEM for Black and Decker called Freewire. They have discontinued the line now but dealers still have them.
They made an Indoor Remote Control FWIR and a Messenger Hub FWMH. The remote has a wheel on it that can do all 16 units of a house code and also have three sets of added buttons. Two are scenes where you can add 4 units and the third is an All Lights On and All Units Off set. The House code is set on the Messenger Hub and the remote is registered to the Hub like a Security Console and a Sensor. The Remote and Hub work on a different RF frequency so a standard X10 receiver will not see the remote, but once processed by the Hub standard X10 signals are sent over the Powerline.
They also made a neat water resistant outdoor module FWLROD that programs like a Socket Rocket. Power it up and send the same X10 signal three times in 30 seconds and it is on the new address. They called it a Lamp Type Module but it clunks like an Appliance Module and the rating label reads like a Appliance Module and I believe it responds to an All Lights on but that is from vague memory.
