August 4th Gen Lock Overheating During Wi-Fi Search -... | digitalhomefaults.org

Technical Background:

The August 4th Gen lock uses a 2.4GHz Wi-Fi radio for direct connection to the home network (IEEE 802.11 b/g/n). The Wi-Fi module draws significant current during network scanning and association. Internal temperature sensors do not appear to have thermal throttling enabled, or are non-functional. Poor signal strength forces higher transmit power, increasing heat. The motor drive circuit could also contribute to overall heat generation if the bolt is binding.

Symptoms:

Observed high case temperature (>45°C) near the Wi-Fi module during network discovery. Event log indicates repeated Wi-Fi scan attempts and possible disconnections. App reports 'Lock Unavailable' or 'Searching...' status.

Possible Causes:

High RF interference on the 2.4GHz band from neighbouring Wi-Fi networks (common in dense urban environments).
Weak Wi-Fi signal (RSSI below -75dBm) requiring the lock to operate at maximum transmit power.
Low battery voltage causing the lock to draw excessive current to maintain Wi-Fi connectivity, combined with increased internal resistance at cold temperatures.
Firmware bug causing the Wi-Fi module to continuously scan for networks.
Internal short circuit or component failure in the Wi-Fi module power supply.
Mechanical binding of the deadbolt, causing the motor to work harder and generate heat affecting nearby electronics.

Solution:

1

Check Wi-Fi signal strength (RSSI) near the lock using a Wi-Fi analyzer app on a smartphone. Aim for RSSI above -65 dBm. If weak, relocate the Wi-Fi router or add a Wi-Fi extender.
2

Replace the batteries with a fresh set of alkaline or lithium batteries known to perform better in cold weather. Monitor battery voltage under load with a multimeter.
3

Update the lock's firmware to the latest version via the August app. Check release notes for any fixes related to Wi-Fi connectivity or power management.
4

If using a Bell Giga Hub or Rogers Ignite router, ensure that the 2.4GHz Wi-Fi channel is set to a less congested channel (1, 6, or 11). Use the router's admin interface to manually select a channel.
5

Inspect the deadbolt and strike plate for any signs of binding. Lubricate the bolt mechanism with silicone lubricant.
6

Perform a factory reset of the lock by following August's official instructions. Re-pair the lock with the August app.
7

Contact August support for warranty replacement if the problem persists after attempting the above steps.

Safety Warning:

Do not attempt to disassemble the lock or repair internal components. Lithium batteries can pose a fire hazard if damaged or short-circuited. Protect your August account with a strong, unique password and enable two-factor authentication. Be aware of physical tampering risks and inspect the lock regularly for any signs of damage.

Prevention:

- Replace batteries annually before the onset of winter to ensure optimal performance in cold temperatures. - Monitor the lock's battery level through the August app. - Regularly check for firmware updates and install them promptly. - Optimize Wi-Fi network placement and configuration to minimize interference and maximize signal strength. - Clean and lubricate the deadbolt mechanism twice a year (spring/fall) to prevent binding.

Expert Tip:

Temporarily disable the Wi-Fi on the August lock via the app and test if the overheating issue resolves. This will isolate the Wi-Fi module as the source of the problem. If overheating stops with Wi-Fi disabled, then focus troubleshooting on Wi-Fi interference and settings.

Frequently Asked Questions

•What is the optimal Wi-Fi signal strength (RSSI) for the August lock?

RSSI should be above -65 dBm for reliable operation.

•What type of batteries are recommended for cold weather performance?

Lithium batteries generally perform better than alkaline batteries in cold temperatures.

•How do I check for Wi-Fi interference on my 2.4 GHz network?

Use a Wi-Fi analyzer app on your smartphone to visualize channel usage and identify congested channels.
