Weiser Lock: Fixing Internal Relay Clicking Noise -... | digitalhomefaults.org

Technical Background:

The Weiser lock utilizes a relay to switch power to the motor drive circuit responsible for actuating the bolt. The relay is controlled by the lock's microcontroller, which interprets signals from the keypad, mobile app (via Zigbee/Z-Wave), and internal sensors. Low voltage, RF interference, or mechanical resistance can cause the relay to rapidly switch, resulting in the clicking noise. The motor drive circuit typically operates at 5-12V DC. Signal strength (RSSI/dBm) between the lock and the hub is crucial for reliable communication.

Symptoms:

Audible clicking from the internal relay mechanism within the Weiser lock body. May coincide with unsuccessful lock/unlock attempts. Check the Weiser app for error codes (e.g., "Motor Failure," "Communication Error") or LED blink patterns (refer to Weiser documentation). Verify that external keypad presses trigger the clicking sound.

Possible Causes:

Low battery voltage: Cold temperatures (-20°C to -40°C) significantly reduce battery capacity and increase internal resistance, leading to voltage drops under load.
RF Interference: 900MHz or 2.4GHz interference from other devices (cordless phones, Wi-Fi routers) can disrupt communication between the lock and the smart home hub, causing erratic relay operation.
Mechanical Binding: Door frame warping due to temperature fluctuations can increase resistance on the bolt, causing the motor to draw more current and stress the relay.
Corroded Relay Contacts: Oxidation on the relay contacts can increase resistance, leading to arcing and clicking.
Faulty Motor Drive Circuit: A failing capacitor or resistor in the motor drive circuit can cause the relay to cycle rapidly.
Firmware Glitch: A software bug can cause the relay to trigger erratically.

Solution:

1

Replace Batteries: Use fresh, high-quality lithium batteries (rated for -40°C). Monitor voltage with a multimeter; voltage should be above the Weiser-specified minimum under load (typically > 6V).
2

Check RF Environment: Use a Wi-Fi analyzer app (e.g., NetSpot, Wi-Fi Analyzer) to identify potential sources of interference on the 2.4 GHz band. Relocate the smart home hub or the Weiser lock to improve signal strength (RSSI).
3

Lubricate Bolt and Strike Plate: Apply a silicone-based lubricant to the bolt and strike plate to reduce friction. Inspect the strike plate alignment; adjust if necessary.
4

Inspect Wiring: If the lock is hardwired (C-wire configuration), verify that the wiring connections are secure and free from corrosion. Measure voltage at the lock with a multimeter.
5

Update Firmware: Use the Weiser app to check for and install any available firmware updates. Ensure the hub also has the latest firmware.
6

Factory Reset: Perform a factory reset of the lock (refer to the Weiser documentation) and re-pair it with the smart home hub. Note that this will erase existing access codes and settings.
7

Consult Weiser Support: If the problem persists, contact Weiser technical support for further assistance.

Safety Warning:

Always disconnect power to the lock before performing any maintenance. Avoid disassembling the lock beyond what is described in the user manual. Be cautious when handling lithium batteries; dispose of them properly at a designated recycling facility. Protect your data by using strong passwords and enabling two-factor authentication on your smart home hub.

Prevention:

- Regularly check battery health, especially before winter. Replace batteries annually or as needed. - Monitor RF environment and relocate hub or lock if interference is detected. - Lubricate bolt and strike plate seasonally to prevent mechanical binding. - Keep the lock's firmware up-to-date. - Consider using a Zigbee or Z-Wave repeater to extend the network range and improve signal strength.

Expert Tip:

Try a three-tap reset sequence: Remove one battery, tap the exterior lock button three times in quick succession, and then reinsert the battery. This can sometimes clear minor firmware glitches. Check the Bell Giga Hub Wi-Fi channel settings to minimize 2.4Ghz congestion if using Bell Fibe.

Frequently Asked Questions

•What is the optimal operating temperature range for my Weiser lock in a Canadian winter?

Weiser locks are generally rated to operate down to -25°C. For optimal performance in temperatures below this, use lithium batteries and ensure proper lubrication.

•How can I check the signal strength (RSSI) of my Weiser lock in the Weiser app?

The Weiser app typically does not display RSSI directly. However, you can infer signal strength from the speed and reliability of lock commands. Consider using a third-party Zigbee/Z-Wave network analyzer for precise measurements.

•My Weiser lock is connected to a Rogers Ignite hub. Are there any known compatibility issues I should be aware of?

Rogers Ignite hubs use Wi-Fi, Zigbee and Z-Wave. Ensure the hub's firmware is up to date and that the Weiser lock is within range. Some users have reported compatibility issues with certain Z-Wave versions; consider a dedicated hub if problems persist.
