August Lock: Calibration Failed Troubleshooting Guide

Troubleshoot August Lock calibration errors in Canada. Fix door lock calibration issues quickly with our expert guide. Secure your smart home now!

Frequently Asked Questions

•What type of batteries should I use in my August lock for cold weather?

Use lithium AA batteries for optimal performance in cold Canadian winters. Lithium batteries maintain voltage better at low temperatures compared to alkaline batteries.

•How can I improve the Wi-Fi signal strength to my August Connect bridge?

Try moving the bridge closer to your router or consider upgrading to a Wi-Fi mesh network. Minimize obstructions between the bridge and the router. Check for interference from other 2.4 GHz devices.

•My August lock still won't calibrate after trying these steps. What should I do?

Contact August support for further assistance. They may be able to provide additional troubleshooting steps or arrange for a warranty replacement if the lock is defective.

How It Works:

The August lock uses a motorized deadbolt mechanism. Calibration involves the lock determining the open and closed positions by measuring motor current and rotational distance via an encoder. The lock communicates wirelessly (Wi-Fi or Z-Wave) to the August Connect bridge or directly to the user's Wi-Fi router (Bell Giga Hub, Rogers Ignite) using TCP/IP over HTTPS. Calibration data is stored locally and in the cloud. RF interference or low battery can interrupt the process.

Expert Tip:

If calibration fails repeatedly, try temporarily disabling Bluetooth on your smartphone during the process. Some Bluetooth devices can interfere with the lock's calibration process, especially if they are actively transmitting data during setup. This forces the lock to rely on Wi-Fi and can bypass potential interference issues.

Possible Causes:

Weak battery voltage, especially in cold Canadian winters (-20°C to -40°C) affecting motor torque.
Door frame misalignment causing excessive friction and motor overload.
Mechanical binding in the deadbolt mechanism (Weiser or Schlage strike plate).
RF interference from other 2.4 GHz devices (microwave, cordless phone) disrupting wireless communication.
Faulty motor or encoder within the August lock.
Incorrect door handing configuration in the August app.

Solution:

1

Replace batteries with new, high-quality lithium AA batteries. Ensure correct polarity. Check battery voltage under load (while the lock is attempting to calibrate) using a multimeter; voltage should not drop below 4.5V.
2

Manually extend and retract the deadbolt. Inspect the strike plate and door frame for any obstructions or binding. Lubricate the deadbolt with graphite lubricant.
3

Temporarily relocate the August Connect bridge (if used) closer to the lock to improve signal strength (RSSI). Use a Wi-Fi analyzer app on your smartphone to check for 2.4GHz interference. Switch Wi-Fi channel on your Bell Giga Hub/Rogers Ignite router if necessary.
4

Perform a hard reset on the August Lock (check August support documentation for the specific reset sequence for your model).
5

Recalibrate the lock through the August app. Ensure correct door handing is selected.
6

If the calibration continues to fail, contact August support for warranty replacement or repair.
7

For C-Wire installations, verify stable 24VAC from the transformer using a multimeter. A fluctuating voltage will cause motor calibration errors.

What to Look For:

Calibration consistently fails during initial setup or after a factory reset. LED ring flashes red and white. The August app displays "Calibration Failed" or "Motor Jammed" error messages. Lock may be unresponsive to manual turn or app commands. Possible grinding noise heard from the motor.

Prevention:

Replace batteries annually, especially before the onset of winter.
Regularly check door frame alignment and lubricate the deadbolt mechanism.
Ensure the August Connect bridge (if used) has a strong and stable Wi-Fi connection. Consider a Wi-Fi mesh network for improved coverage in larger homes.
Keep the August app and lock firmware updated to the latest versions via over-the-air (OTA) updates.
Check screw tightness every 6 months on both the lock chassis and the strike plate.
