Context:
To achieve optimal battery life (4-5 months) for Yale locks utilizing Wi-Fi, consider the following network setup recommendations:
Network Configuration Best Practices:
Wi-Fi Settings: Ensure your network is set to 802.11b/g/n standard and broadcasting 2.4 ghz
Avoid Mesh Networks: Mesh networks can significantly increase lock battery drain due to elevated network traffic as the lock frequently switches between access points.
Proximity to Access Point (AP): Ensure the AP is close to the lock. A weak signal can lead to frequent network reconnections, which also deplete battery life.
Unique SSID for APs: If using multiple access points (e.g., range extenders), configure each with a unique SSID. Identical SSIDs can cause the lock to "jump" between APs, similar to mesh networks, resulting in increased traffic and battery drain.
Sufficient DHCP Leases: Verify that enough DHCP leases are available for all wireless devices on site.
Firewall Configuration: If a firewall is in use, ensure it permits Yale lock connections.
TCP/IP Timeout (if applicable): If possible, set the TCP/IP timeout to a maximum value or disable it for devices not in constant use.
Minimize Radio Interference: Evaluate the site for any external radio interference that could disrupt communications.
Recommended Wi-Fi AP Brands:
Yale's data indicates that certain Wi-Fi AP brands correlate with longer lock battery life:
Best Performing: Atheros, Sagemcom, Broadcom, ASUS, and Arcadyan.
Good Performance: Arris and Xfinity.
Avoid: OpenWrt APs and TP-Link mesh networks, as they have shown extreme battery drain with Yale locks.
