WiFi vs Zigbee & Z-Wave
Detailed comparison to help you choose the right smart home protocols for your smart home.
The protocol you choose affects everything: battery life, reliability, scalability, and cost. WiFi devices connect directly to your router — simple but limited. Zigbee and Z-Wave use mesh networking through a dedicated hub, enabling hundreds of devices with years of battery life. Start with WiFi for a few devices; graduate to hub protocols as you scale.
