Key Benefits of Z-IP Gateway*
Features
IP applications reach Z-Wave nodes via IP addresses
Z/IP Packets from LAN IP applications are terminated and forwarded as Z-Wave commands to Z-Wave Nodes
Z-Wave nodes are identified by IPv6 and IPv4 host addresses
Resource & Service Discovery (mDNS)
Remote Access and Configuration
Z-Wave SmartStart Auto-inclusion
Z-Wave Security 2 support
Features
Z-Wave Mailbox Service – Support for Non-Listening nodes
Installation and Maintenance framework
Firmware Update of Z-Wave module attached to the Z/IP Gateway
Migration to Z/IP Gateway from non-Z/IP Gateways
Back-up/Recover of Z-Wave network and product data
*The Z/IP gateway is a free reference design intended for development and demonstration purposes only. It is provided as is, with no warranties. Customers are advised to conduct security and compliance testing of all gateways during the product design process.
