The LOM-15 is the Evolve in-wall outlet, used for switching ON/OFF plug-loads. They can be used on any bulb type, with a 15A limit.
There is a small LED on the device, which illuminates when the circuit is OFF.
The BOTTOM receptacle is the “controlled” side, which responds to commands with the Evolve network. The top receptacle receives constant power and does not respond to any commands. The middle button is used for programming and local control over the bottom receptacle.
