Frequently Asked Questions
Can Zigbee smart locks interfere with WiFi?
Zigbee and WiFi both use the 2.4 GHz band but on different channels. Properly configured, they coexist well. Choose Zigbee channels 15, 20, or 25 to avoid WiFi overlap.
How long do Zigbee lock batteries last?
Zigbee's ultra-low power consumption typically yields 18+ months of battery life, making it one of the most efficient protocols for smart locks.
What hubs work with Zigbee smart locks?
Popular options include Amazon Echo (4th gen), SmartThings, Hubitat, and Home Assistant with a Zigbee coordinator. Many Apple HomePod devices also include Zigbee/Thread radios.
