1INTRODUCTION
1.1 What’s Z-WaveTM
Z-Wave is international wireless protocol used for Smart Home. It’s a mesh network technology to ensure reliable two-way
communication with each other.
This product can be operated in any Z-Wave network with other Z-Wave certified devices from other manufacturers. All mains
operated nodes within the network will act as repeaters regardless of vendor to increase reliability of the network.
1.2 About Custos WWD
Custos Wireless Water Detector “Custos WWD” detects Water Leakage with long battery operation lifespan, super tiny form
factor detects water from either in body detection probe on 4 sides as well as optional remote wired water detection probe. It is a
perfect companion for Custos BVS to work in concerto as a complete solution to close water valve once WWD detected water
leak (need proper set up on App or gateway configuration).
It gets Z-Wave Plus Certification means it can be worked with other Z-Wave certified gateways or end-devices from other
manufacturers. Custos WWD also supports SmartStart.
1.3 What’s SmartStart
SmartStart enabled products can be added into a Z-Wave network by scanning the Z-Wave QR Code present on the product with
a controller providing SmartStart inclusion. No further action is required and the SmartStart product will be added automatically
within 10 minutes of being switched on in the network vicinity.
