How to Update Your Smart Devices for Better Security

How to Update Your Smart Devices for Better Security: In 2025, smart devices ranging from smart TVs and thermostats to security cameras and voice assistants are integral to modern homes, offering convenience and connectivity.

However, their internet connectivity makes them vulnerable to cyberattacks, with over 1.5 billion IoT device breaches reported in 2024 alone, according to cybersecurity reports. Regular updates are critical to maintaining security, as they patch vulnerabilities, enhance performance, and protect personal data.

Why Updating Smart Devices Matters

Smart devices often collect sensitive data, such as location, voice recordings, or video feeds, making them prime targets for hackers. Outdated firmware or software can expose vulnerabilities that allow unauthorized access, data theft, or even device hijacking for botnets. For example, a 2024 study by Kaspersky highlighted how unpatched smart cameras could be exploited to spy on users. Regular updates deliver security patches, bug fixes, and new features, reducing risks and ensuring compliance with privacy standards like GDPR or CCPA. Updates also improve device performance, preventing lag or compatibility issues with new apps or protocols.

Steps to Update Your Smart Devices

1. Identify Your Devices

Start by creating an inventory of all smart devices in your home, including:

Smart Home Hubs: Amazon Echo, Google Nest Hub, Apple HomePod
Appliances: Smart TVs, refrigerators, thermostats (e.g., Nest, Ecobee)
Security Devices: Cameras (e.g., Ring, Arlo), doorbells, smart locks
Wearables and Health Devices: Smartwatches, fitness trackers
Networking Equipment: Routers, mesh Wi-Fi systems

Check each device’s brand, model, and current firmware/software version, typically found in the device’s settings or companion app.

2. Enable Automatic Updates

Most smart devices support automatic updates, which ensure timely security patches without manual intervention. To enable:

Smart TVs: On Samsung TVs, go to Settings > Support > Software Update > Auto Update. For LG, navigate to Settings > General > About This TV > Allow Automatic Updates.
Smart Speakers: For Amazon Echo, open the Alexa app, go to Devices > Echo & Alexa > [Device Name] > Change Settings > Device Software Version, and enable automatic updates. Google Nest devices update automatically when connected to Wi-Fi.
Security Cameras: In the Ring app, go to Device Settings > General Settings > Automatic Firmware Updates. Arlo cameras update via the Arlo Secure app under Device Info.
Thermostats: Nest thermostats update automatically via Wi-Fi, but you can check status in the Nest app under Settings > Software.

Verify that your device is connected to a stable Wi-Fi network, as updates require internet access.

3. Manually Check for Updates

If automatic updates are unavailable or disabled, manually check for updates:

Smartphones/Tablets: For iOS, go to Settings > General > Software Update. For Android, navigate to Settings > System > System Update.
Smart TVs: On Roku TVs, go to Settings > System > System Update > Check Now. For Fire TV, select Settings > My Fire TV > About > Check for Updates.
Routers: Access your router’s web interface (e.g., 192.168.1.1) or app (e.g., Netgear Nighthawk, TP-Link Tether) and look for a Firmware Update section.
Other Devices: Check the manufacturer’s app or website for firmware updates. For example, Philips Hue bulbs update via the Hue app under Settings > Software Update.

Perform manual checks monthly to catch missed updates.

4. Secure Your Network

A secure Wi-Fi network is essential for safe updates and device protection:

Use a strong, unique password with WPA3 encryption (or WPA2 if WPA3 is unavailable).
Create a separate guest network for smart devices to isolate them from personal devices like laptops.
Regularly update your router’s firmware to patch vulnerabilities. For example, ASUS routers notify users of updates via the ASUS Router app.
Disable Universal Plug and Play (UPnP) to prevent unauthorized device access.

5. Monitor Manufacturer Support

Check if your device is still supported, as manufacturers may end updates for older models (e.g., after 3–5 years). Visit the manufacturer’s website or support portal to confirm. If a device is no longer supported, consider replacing it to maintain security.

6. Back Up Device Settings

Before updating, back up critical settings, especially for devices like smart locks or thermostats. For example:

Nest Thermostat: Save schedules in the Nest app.
Smart Locks (e.g., August): Export access codes via the August Home app.
This ensures you can restore configurations if an update resets the device.

7. Test Post-Update Functionality

After updating, test devices to ensure they function correctly. For cameras, verify live feeds; for smart locks, test remote access. If issues arise, check the manufacturer’s support forums or contact customer service.

8. Remove Unused Devices

Deactivate or reset unused smart devices to factory settings before disposal to prevent data leaks. For example, reset an Amazon Echo via the Alexa app under Devices > Echo & Alexa > [Device Name] > Factory Reset.

Device-Specific Tips

Smart TVs: Ensure apps like Netflix or cloud gaming services are updated via the TV’s app store. Restart the TV after firmware updates to avoid glitches.
Smart Speakers: Update companion apps (e.g., Alexa, Google Home) to maintain compatibility with device firmware.
Security Cameras: Regularly check for firmware updates, as cameras are frequent hacking targets. Enable two-factor authentication (2FA) in the app.
Routers: Prioritize updates, as routers are gateways to your network. Use apps like Eero or Orbi for seamless updates.

Best Practices for Ongoing Security

Use Strong Passwords: Set unique passwords for each device and app, ideally managed by a password manager like LastPass.
Enable 2FA: Activate two-factor authentication on apps controlling smart devices (e.g., Ring, Nest).
Monitor Activity: Check device logs for unusual activity, such as unauthorized logins, via companion apps.
Limit Data Sharing: Review privacy settings to disable unnecessary data collection (e.g., voice recording on smart speakers).
Regular Audits: Review connected devices quarterly to ensure all are updated and secure.

FAQs

Why do smart devices need regular updates?

Updates patch security vulnerabilities, fix bugs, and improve performance. Without them, devices are at risk of hacking or data breaches.

How often should I check for updates?

Enable automatic updates where possible. For manual checks, review monthly or when manufacturers announce security patches.

What if my device doesn’t support automatic updates?

Manually check for updates via the device’s settings, app, or manufacturer’s website. If unsupported, consider upgrading to a newer model.

Can updates cause device issues?

Rarely, updates may introduce bugs or reset settings. Back up configurations before updating and test functionality afterward. Contact support if issues persist.

Are older smart devices safe to use?

Devices no longer receiving updates are vulnerable. Check manufacturer support status and replace unsupported devices to maintain security.

How do I know if my network is secure for updates?

Use WPA3 encryption, a strong Wi-Fi password, and a separate guest network for smart devices. Regularly update your router’s firmware.
