August Keypad: Fixing Sticking Buttons - Smart Home | digitalhomefaults.org

Technical Background:

The August Keypad communicates wirelessly (typically via Bluetooth) with the August Smart Lock. Power is supplied by two AAA batteries. Button presses are registered via tactile switches connected to a microcontroller, which then transmits the code to the lock. Keypad relies on mechanical button action and tactile switch integrity. Operating temperature impacts battery impedance and switch responsiveness. RF interference can affect communication reliability.

Symptoms:

Keypad buttons remain depressed after being pressed, requiring excessive force for release or failing to register subsequent presses. LED may exhibit unusual flickering or remain illuminated. App may intermittently report incorrect PIN entries or key presses. Increased latency observed between button press and lock response. Cold weather exacerbates symptoms.

Possible Causes:

Accumulation of dirt, debris, or ice within the button housing, causing mechanical obstruction.
Low battery voltage, leading to inconsistent button press detection.
Mechanical wear or damage to the tactile switch beneath the button.
Extreme cold temperatures (-20°C to -40°C) affecting the flexibility of the button material or increasing battery impedance.
RF interference from other devices operating on the 2.4GHz band (Wi-Fi routers, microwave ovens).
Warping of the keypad housing due to temperature fluctuations, causing binding of the buttons.

Solution:

1

Power cycle the keypad: Remove batteries, wait 30 seconds, re-insert fresh batteries (Energizer Lithium recommended for Canadian winters).
2

Clean the keypad: Use compressed air to dislodge any debris from around the buttons. Gently wipe the surface with a soft, slightly damp cloth (distilled water).
3

Inspect button movement: Ensure buttons move freely without excessive friction. Manually exercise each button multiple times.
4

Check battery contacts: Clean battery contacts with a cotton swab dipped in isopropyl alcohol.
5

Verify firmware: Using the August app, ensure the keypad firmware is up to date. OTA updates enhance stability.
6

Test RF environment: Use a Wi-Fi analyzer app (e.g., NetSpot) on your smartphone to check for 2.4GHz interference. Move the August keypad away from potential sources of interference, if possible.
7

Factory Reset: If problems persist, perform a factory reset of the keypad (consult August documentation) and re-pair with the lock.

Safety Warning:

Always handle batteries with care. Dispose of used batteries properly according to local Canadian regulations. Ensure the keypad is securely mounted to prevent tampering. Avoid using excessive force when pressing the buttons, as this can damage the tactile switches. Regularly verify the functionality of the lock using a physical key as a backup in case of keypad failure. Secure your Wi-Fi network with a strong password to prevent unauthorized access.

Prevention:

- Replace batteries annually, ideally before the onset of winter. Monitor battery health via the August app. - Regularly clean the keypad to prevent debris buildup. Use a silicone sealant around the keypad edges for added weather protection. - Schedule periodic firmware updates to maintain optimal performance. - Consider using a keypad cover or enclosure to shield the keypad from extreme weather conditions.

Expert Tip:

Try lightly lubricating the edges of the sticky buttons with a small amount of silicone grease (dielectric grease) to reduce friction. Use sparingly and avoid getting grease on the keypad's electronic components. Perform a three-tap reset sequence (press and hold any button for 5 seconds, release, then press three times quickly) to clear temporary glitches in the keypad's memory. Check your Bell Giga Hub settings for excessive 2.4Ghz congestion.

Frequently Asked Questions

•How do I reset my August Keypad?

Refer to the August website for precise reset instructions. Generally requires holding a button for 5 seconds until the LED blinks a certain way. You will then need to re-pair the keypad with your August lock.

•What type of batteries are best for my August Keypad in cold weather?

Lithium AAA batteries (e.g., Energizer Lithium) are recommended for optimal performance in cold Canadian winters. They have a wider operating temperature range and lower internal resistance compared to alkaline batteries.

•How do I improve the wireless signal strength to my August Keypad?

Move your Wi-Fi router closer to the keypad, or consider adding a Wi-Fi extender to improve coverage. Ensure the keypad is not obstructed by metal objects or walls. Periodically check for and mitigate interference from other 2.4GHz devices.
