The XPT-NS and XPT-1-NS is an X10 power line controller. It can send X10 commands to other X10 modules. It has no power line receiver or load controls in it. So it can not be controlled by other X10 transmitters.
The Power Line communications only Insteon Switches. All supported an X10 Primary Address. Some also an X10 Scene Address
2476D 600 watt dimmer, 2476DH 1000 watt dimmer, 2476S Relay type On/Off.
The Paddle Color Change Kits are still available.
The Bargraph color LED Light Pipe kit are still available. I am using Frosted and Blue.
The less feature Icon versions with a single Green or Amber Off LED are 2876D and 2876S. Also supported an X10 primary Address.
There was an issue with some production runs.
The small tact switches the paddles pushed. Would click but not make a connection. So local control didn't work.
If you get some used ones. Verify from the seller the paddles are not intermittent.
I also mentioned the dimmer versions use the %Dim command that AHP and the CM15A do not use.
Local Paddle activation with B1 X10 address.
Dimming and brightening sent a %Dim command back on the power lines.

The earlier hardware Dual Band also supported X10. I don't have the revision where X10 was removed.
