Once it's installed, is it difficult to add additional devices to the Pulse system? Not at all. Some devices, such as lamp or small appliance on/off modules, can simply be plugged into existing electrical outlets. Others require a little more skill, and may need the assistance of a professional electrician. To enroll additional devices, simply go to the System tab of your Pulse device and select “Manage Devices.” On-screen instructions will guide you through the installation process. (Please note that each device has unique requirements that need to be followed.) For Z-Wave devices, press the “Sync” button on each device to connect the unit.
