But now that there’s a two-way IP to Z-Wave bridge available most of those limitations go way.
The ZIPR is a Gateway reference design and now it has been rolled out to some large commercial installation we asked Sigma Designs what this means in practical terms.
They told us…
Normally you can have 232 nodes on a single network but companies tie networks together with our Z-Wave for IP (Z/IP) application software layers. The Wynn hotel in Las Vegas has 68,000 nodes in 2,800 rooms where every room is one network with up to 30 nodes in the large suites and all rooms are connected through Z/IP.
The ZIPR is a bi-directional bridge and it’s IPv6 compatible.
The ZIPR is a ‘non-application-specific’ gateway. You simply plug it into an IP network using its Ethernet connection and add it to a Z-Wave network. Instantly, IP addresses will be assigned to every Z-Wave end-point or function. If the IP network is using IPv4 addressing, these will be IPv4 addresses; if IPv6, these will be IPv6 addresses. The user on the IP side can now fully communicate with the Z-Wave network using user datagram protocol (UDP) messages. This is a full-function, bi-directional bridge.
