August Lock Flashing Green But Door Still Locked:... | digitalhomefaults.org

Technical Background:

The August Lock relies on a motor drive circuit to actuate the deadbolt. A flashing green LED typically indicates a communication error between the lock's control board and the deadbolt position sensor, or a failure to calibrate the motor. Low battery impedance in cold Canadian winters can affect motor torque. RF interference on the 2.4 GHz band (shared with Wi-Fi) can disrupt communication with the August Connect bridge or integrated Wi-Fi.

Symptoms:

Observed continuous green LED flashing on the August Lock unit while the door remains locked. No mechanical unlocking is possible via the August app or physical turn mechanism. The mobile app may display a 'Door Stuck' or 'Calibration Error' message. Possible Z-Wave/Wi-Fi connectivity issues indicated in the app settings.

Possible Causes:

Low battery voltage, especially in temperatures below -20°C, reducing motor torque.
Mechanical binding of the deadbolt due to door frame warping from seasonal temperature changes.
Wi-Fi or Z-Wave signal interference from other devices (microwaves, cordless phones) operating on the 2.4 GHz or 900MHz bands.
Incorrect deadbolt system or strike plate alignment, causing excessive friction.
Calibration failure of the internal position sensor.
Corrupted firmware or failed OTA (Over-The-Air) update.

Solution:

1

Replace the batteries with fresh, high-quality lithium batteries, ensuring proper polarity. Note the date of install.
2

Manually unlock and lock the door several times to check for mechanical binding. Inspect the strike plate for wear or misalignment. Lubricate the deadbolt mechanism with graphite-based lubricant (NOT oil-based).
3

Use a Wi-Fi analyzer app (available on iOS and Android) to check for signal interference on the 2.4 GHz band. Reposition the August Connect bridge or Wi-Fi router to minimize interference. Consider a dedicated 5GHz network for less interference if available.
4

Force a recalibration of the August Lock through the app's settings menu. This may require removing and reinstalling the lock.
5

Check the August app for firmware updates and install any available updates. Ensure a stable Wi-Fi connection during the update process. Bell Giga Hub users should verify that the 2.4 GHz and 5 GHz bands are broadcasting separately.
6

As a last resort, perform a factory reset of the August Lock according to the manufacturer's instructions (usually involving holding down a button on the lock for a specific duration).
7

If the problem persists, contact August support for warranty assistance.

Safety Warning:

Data privacy is paramount. Ensure two-factor authentication (2FA) is enabled on your August account. Protect against physical tampering by regularly inspecting the lock for damage or signs of forced entry. Do NOT attempt to disassemble the August Lock yourself, as this could void the warranty and create a safety hazard. Dispose of used batteries responsibly at designated recycling centers.

Prevention:

- Replace batteries annually, ideally before the onset of winter. Use only high-quality lithium batteries rated for extreme cold temperatures. - Periodically check for and install firmware updates through the August app. - Regularly inspect and lubricate the deadbolt mechanism to prevent mechanical binding. - Monitor Wi-Fi signal strength and minimize interference from other devices.

Expert Tip:

If your August Lock is connected via Z-Wave, try excluding and re-including it from your Z-Wave network. This can often resolve communication issues caused by outdated Z-Wave routing tables. Press the August button three times rapidly to initiate Z-Wave exclusion mode.

Frequently Asked Questions

•How do I reset my August Lock?

Refer to the August Lock user manual or online documentation for specific reset instructions. Typically, this involves pressing and holding a button on the lock for a certain duration.
