August DoorSense: Door Showing Open When Closed -... | digitalhomefaults.org

Technical Background:

The August DoorSense relies on magnetic field disruption. A magnet within the doorframe interacts with a Hall effect sensor inside the DoorSense module. The module interprets changes in magnetic field strength to determine door open/closed status. This data is transmitted via Bluetooth Low Energy (BLE) to the August Connect or directly to the August lock. Interference on the 2.4GHz band (BLE) or a weakened magnetic field can cause false readings. Power is supplied by a CR123A lithium battery. Low temperatures increase internal battery resistance.

Symptoms:

The August app displays "Door Open" status despite the door being physically closed and locked. No error messages are present in the August app event log. The DoorSense unit LED may flash amber or red intermittently. Inconsistent readings are reported regardless of the door's lock status. Occasional audible clicks are heard from the DoorSense module without a corresponding state change.

Possible Causes:

Weakened magnetic field due to misaligned or displaced magnet.
Low battery voltage, particularly exacerbated by cold Canadian winters (-20°C to -40°C).
RF interference on the 2.4GHz band from other devices (Wi-Fi routers, microwave ovens) operating nearby.
Mechanical binding of the doorframe due to seasonal temperature and humidity changes, affecting the door's alignment with the magnet.
Faulty Hall effect sensor within the DoorSense module.
Firmware bugs in the DoorSense module or the August app.

Solution:

1

Verify magnet alignment: Ensure the magnet on the doorframe is correctly aligned with the DoorSense module. The magnet should be within 1/4 inch of the sensor when the door is closed. Reposition the magnet if necessary, using the included adhesive strips.
2

Replace the battery: Install a new CR123A lithium battery. Use a high-quality brand known for low-temperature performance (e.g., Energizer Ultimate Lithium).
3

Check for RF interference: Use a Wi-Fi analyzer app on your smartphone to scan for 2.4GHz interference. If interference is high, try changing the Wi-Fi channel on your router or moving the August Connect closer to the DoorSense.
4

Calibrate DoorSense: Remove and reinstall the DoorSense module. Re-calibrate the sensor through the August app. Follow the on-screen instructions carefully.
5

Inspect the doorframe: Check for any signs of warping or misalignment that could be preventing the door from closing properly. If necessary, adjust the door hinges or strike plate to ensure a proper fit. Consult a door installation professional if significant adjustments are needed.
6

Update firmware: Ensure both the August lock and DoorSense module are running the latest firmware versions. Check for updates within the August app.
7

Factory reset: As a last resort, perform a factory reset of the DoorSense module. Refer to the August support website for instructions. Note that this will require re-pairing the device with your August account.

Safety Warning:

Do not attempt to disassemble the DoorSense module. Lithium batteries can pose a fire hazard if mishandled. Ensure the battery compartment is securely closed after replacing the battery. Protect your August account with a strong, unique password and enable two-factor authentication. Be aware of potential physical tampering with the DoorSense module. Report any suspicious activity to local authorities.

Prevention:

- Replace the DoorSense battery annually, ideally before the onset of winter. - Periodically check the magnet alignment and reposition if necessary. - Monitor the August app for low battery warnings. - Regularly update the firmware for both the August lock and DoorSense module. - Consider using a Wi-Fi mesh network to improve 2.4GHz coverage throughout your home.

Expert Tip:

If the DoorSense frequently loses connection, try assigning a static IP address to your August Connect within your router's settings (consult Bell Giga Hub/Rogers Ignite documentation for setup details). This can improve network stability and reduce intermittent connectivity issues. Also ensure proper grounding of any metal door frames.

Frequently Asked Questions

•My August DoorSense keeps disconnecting. What should I do?

First, ensure the August Connect is within close proximity to both the August lock and the DoorSense. Check your Wi-Fi signal strength near the August Connect. Try assigning a static IP address to the Connect on your router. If the problem persists, consider upgrading your Wi-Fi router or adding a Wi-Fi extender.

•The DoorSense magnet keeps falling off. What adhesive should I use?

Clean the surface of both the doorframe and the magnet with isopropyl alcohol. Use a strong, weather-resistant adhesive such as 3M VHB tape. Ensure the adhesive is fully cured before using the door.

•How do I check the battery level of my August DoorSense?

The battery level is displayed within the August app. Navigate to the DoorSense settings to view the current battery percentage. You will also receive a notification when the battery is low.
