This is the "Z-Wave Plus"-certified add-on module that HomeSeer fans have been waiting for. The HomeSeer Z-NET Remote Z-Wave Interface communicates over the Internet with your existing HomeSeer HS3-based system to improve system performance. Because the Z-NET is IP-based, you can install it almost anywhere on your property. Its integrated antenna has also been optimized to improve wireless range. The Z-NET is perfect for creating large, complex Z-Wave networks that can be controlled through just one interface! HomeSeer designed the Z-NET to allow a hassle-free, reliable system upgrade with Z-Trollers, Z-Sticks, SmartSticks and almost all other Z-Wave interfaces. The unit also supports Network Wide Inclusion (NWI), so you can easily include Z-Wave devices that are outside the primary controller's range. The Z-NET has keyhole slots for wall mounting, or it can be placed on a shelf. The unit plugs into a power outlet using the included power supply, and connects to the Internet via Ethernet. You can optionally enable a wireless connection by adding the USB WiFi Adapter (sold separately), which plugs into a USB port on the Z-NET unit. FEATURES: Improves performance of existing systems running HS3 software. Z-Wave Plus certification enables wide Z-Wave compatibility. Optimized antenna design for improved range and performance. Adds support for 232 Z-Wave devices per Z-NET installed. Incorporate as many Z-NET units as you need. Built-in Ethernet jack (optional WiFi adapter sold separately). CONTENTS: Z-NET Unit, AC Power Supply, Quickstart Guide. NOTE: Not intended for use as a standalone controller. Must be connected to a system with HS3 software (plug-in v3.0.0.196 or higher). Not compatible with HS2 or earlier versions.
