August DoorSense: Fixing Magnetic Interference on Metal... | digitalhomefaults.org

Technical Background:

DoorSense utilizes a magnetic field sensor to detect the proximity of a magnet (typically embedded in the door frame). The sensor transmits door status data wirelessly (likely Bluetooth LE or Z-Wave) to the August lock. A metal door frame can interfere with this magnetic field, causing false readings. Power is provided by a small coin cell battery, voltage drops in extreme cold (-20°C to -40°C) affect sensor sensitivity.

Symptoms:

DoorSense reports incorrect door status (open/closed) despite the door's actual position. The August app displays error messages such as 'DoorSense not calibrated' or 'DoorSense offline'. The lock LED may blink red indicating a DoorSense malfunction. Intermittent operation observed, especially during temperature fluctuations.

Possible Causes:

Magnetic field interference from the steel door frame disrupting the sensor's readings.
Weak battery in the DoorSense sensor, exacerbated by Canadian winter temperatures causing impedance increase.
Misalignment of the DoorSense sensor and the magnet in the door frame.
Physical damage to the DoorSense sensor or its internal components (e.g., moisture ingress).
Firmware incompatibility between the August lock and DoorSense.
Radio Frequency (RF) Interference on the 2.4 GHz band (Wi-Fi) disrupting communication.

Solution:

1

Relocate DoorSense: Experiment with repositioning the DoorSense sensor and magnet slightly to find a location less susceptible to magnetic interference. Try moving it further away from the metal frame's edge.
2

Shielding: Apply a non-magnetic shielding material (e.g., aluminum foil) between the door frame and the DoorSense sensor to reduce magnetic interference. Ensure proper grounding.
3

Battery Replacement: Replace the DoorSense battery with a new, high-quality lithium coin cell battery (CR2450 or similar). Ensure correct polarity. Test voltage under load (minimum 2.8V).
4

Calibration: Recalibrate the DoorSense sensor through the August app. Follow the in-app instructions carefully. Reboot the August lock after calibration.
5

Firmware Update: Check for and install any available firmware updates for both the August lock and DoorSense via the August app. A stable Wi-Fi connection (2.4GHz) is required. Verify router compatibility (Bell Giga Hub, Rogers Ignite).
6

Factory Reset (If Necessary): Perform a factory reset of the DoorSense sensor and re-pair it with the August lock. Consult the August support documentation for the correct reset procedure. Document original settings before reset.
7

Check Mounting: Verify that the DoorSense sensor and magnet are securely mounted and properly aligned. Use appropriate fasteners for the door frame material.

Safety Warning:

Data privacy is paramount. Change your August account password regularly and enable two-factor authentication. Securely store any backup unlock keys. Protect the physical lock from tampering. Avoid DIY electrical modifications. Contact a certified electrician for any wiring issues.

Prevention:

- Regularly check the DoorSense battery level in the August app, especially before the winter months. Replace the battery proactively. - Periodically recalibrate the DoorSense sensor through the August app. - Keep the area around the DoorSense sensor clean and free of debris. - Inspect the sensor and magnet for any signs of physical damage. - Maintain the August lock and DoorSense firmware up-to-date.

Expert Tip:

To diagnose magnetic interference, temporarily move the DoorSense sensor and magnet away from the door frame (e.g., holding them in your hand) and observe if the DoorSense readings become accurate. This isolates the door frame as the source of the interference.

Frequently Asked Questions

•Why is my August DoorSense not working after a power outage?

After a power outage, the August lock and DoorSense may lose their connection. Ensure your Wi-Fi router is back online and that the August lock has reconnected to the network. Recalibrate DoorSense through the August app if necessary.

•How do I change the battery in my August DoorSense?

The DoorSense sensor uses a coin cell battery (typically CR2450). Refer to the August support documentation or online videos for step-by-step instructions on how to safely replace the battery. Ensure correct polarity.

•Is the August DoorSense compatible with all types of doors?

August DoorSense is designed to work with most standard doors. However, thick metal doors or doors with significant magnetic interference may require adjustments to the sensor placement or additional shielding.
