Is It Safe To Leave Smart Home Devices On While Traveling Or Should You Unplug

Smart home technology has transformed how we manage security, comfort, and convenience in our homes. From smart thermostats that adjust temperatures remotely to cameras that stream live footage from your phone, these devices offer peace of mind—especially when you're away. But when planning a trip, a common question arises: Should you leave your smart devices running, or is it safer to unplug them?

The answer isn’t always straightforward. While some devices enhance security during your absence, others may pose privacy risks, consume unnecessary power, or become vulnerable to cyber threats. Understanding which devices to keep online—and which to shut down—can help you strike the right balance between safety, efficiency, and digital hygiene.

Understanding the Risks of Leaving Devices On

Leaving smart home devices powered on while traveling introduces several potential concerns. These range from cybersecurity vulnerabilities to physical risks like overheating or electrical surges.

Cybersecurity threats are among the most pressing issues. Connected devices often rely on cloud services and mobile apps for remote access. If your account credentials are weak or reused across platforms, hackers could gain control of your cameras, door locks, or voice assistants. A compromised smart camera, for example, might allow unauthorized viewing of your empty home—potentially tipping off intruders or violating your privacy.

According to the Federal Trade Commission (FTC), millions of IoT (Internet of Things) devices are targeted annually due to poor password hygiene and outdated firmware. “Many consumers don’t realize that their smart thermostat or baby monitor can be an entry point for hackers,” says cybersecurity analyst Lisa Tran. “Just because a device seems minor doesn’t mean it’s not a risk.”

Another concern is electrical safety. While rare, faulty wiring or power surges during storms can damage plugged-in electronics—or worse, cause fires. Devices with batteries, such as smart speakers or hubs, may overheat if left charging indefinitely. Even energy-efficient gadgets draw \"phantom load,\" contributing to higher electricity bills over time.

Tip: Unplug devices with large transformers or those known to generate heat after prolonged use, especially if they’re near flammable materials.

Which Smart Devices Should Stay On?

Not all smart devices should be turned off. Some provide critical functions that enhance home safety and monitoring while you're away. The key is identifying which ones serve a protective role and ensuring they remain secure and functional.

• Smart security cameras: These deter burglars and allow real-time monitoring. Many models send motion alerts directly to your phone, giving you immediate awareness of unusual activity.
• Video doorbells: Devices like Ring or Nest Hello let you see who’s at your door—even if no one answers. This simulates occupancy and discourages package theft.
• Smart locks: If family members or pet sitters need access, keeping your lock connected ensures secure entry without hiding spare keys.
• Water leak detectors: These can prevent catastrophic flooding by alerting you to leaks from burst pipes or malfunctioning appliances.
• Security systems and sensors: Door/window contact sensors and glass-break detectors integrated with alarm systems should remain active to trigger notifications or professional monitoring.

These devices are designed for continuous operation and typically include built-in safeguards against tampering. However, ensure they’re updated with the latest firmware and protected by strong, unique passwords. Two-factor authentication (2FA) should be enabled wherever possible.

Which Devices Should You Unplug?

Convenience-driven smart devices often don’t require constant connectivity and may introduce more risk than benefit when left unattended. Consider disconnecting the following:

Device	Why Unplug?	Alternative
Smart speakers (e.g., Alexa, Google Home)	Voice assistants can be hacked; microphones may record unintended audio.	Disable microphone physically or unplug.
Smart displays	Cameras and screens increase privacy exposure.	Turn off or cover camera and disable wake words.
Smart plugs controlling non-essential items	Risk of surge damage; no functional benefit when away.	Unplug both the device and the appliance it controls.
Gaming consoles & streaming boxes	High power draw; potential software updates or remote access risks.	Power down completely or use a smart plug with scheduling.
Unused smart kitchen appliances	Fire hazard if malfunctioning; no practical use while traveling.	Unplug coffee makers, air fryers, etc.

Even devices marketed as “energy-saving” can accumulate wear over time when left in standby mode. Unplugging reduces electronic stress and minimizes attack surfaces for cyber intrusions.

Step-by-Step: Preparing Your Smart Home for Travel

Before locking the door, follow this structured routine to optimize device usage, security, and energy efficiency:

1. Update all firmware and apps: Check for pending updates on your router, hub, and individual devices. Outdated software is a primary vector for breaches.
2. Enable travel modes: Some systems (like Nest thermostats or Arlo cameras) offer a “vacation mode” that randomizes lights or disables certain alerts to simulate presence.
3. Review access permissions: Remove temporary users (e.g., house cleaners) and revoke app access for unused third-party integrations.
4. Secure your Wi-Fi network: Change your Wi-Fi password periodically and avoid using default SSID names that reveal your identity (e.g., “SmithFamilyNetwork”).
5. Unplug non-critical devices: Focus on high-draw or high-risk electronics. Use smart power strips to simplify shutdowns.
6. Test remote access: Ensure you can still view camera feeds or receive alerts from your destination. Verify two-factor authentication works.
7. Set up automated routines: Schedule lights to turn on/off at different times using smart bulbs or plugs to create the illusion of occupancy.

Tip: Label your circuit breakers so you can quickly cut power to specific rooms if needed—without shutting down security systems.

Real-World Scenario: A Cautionary Tale

In 2022, a family from Austin, Texas, returned from a two-week vacation to discover their home had been burglarized. Surprisingly, their smart doorbell recorded the entire break-in—but they never received an alert. Investigation revealed that the device had lost Wi-Fi connectivity due to a router reboot triggered by a neighborhood power flicker. Because the system wasn’t set to send push notifications via cellular backup, the homeowners remained unaware.

Additionally, their smart TV and gaming console were left on, drawing unnecessary power and increasing internal temperature. One device showed signs of overheating, raising concerns about fire risk.

This case highlights two oversights: failure to ensure redundant alert delivery and neglecting to power down non-essential electronics. Had they followed a pre-travel checklist, they might have avoided both the security lapse and potential equipment damage.

Frequently Asked Questions

Can someone hack my smart home while I'm away?

Yes, though the likelihood depends on your security practices. Weak passwords, unpatched software, and unsecured Wi-Fi networks make devices vulnerable. Using strong, unique passwords, enabling 2FA, and updating firmware significantly reduce this risk.

Should I turn off my Wi-Fi completely when traveling?

Only if no devices require internet access. Turning off Wi-Fi disables cameras, alarms, and remote monitoring. Instead, consider creating a separate guest network for essential devices and disabling the main network if feasible. Alternatively, use a router with scheduling features to limit bandwidth or access hours.

Do smart devices use a lot of electricity when idle?

Individually, most devices consume minimal power in standby mode—often less than 5 watts. However, a home with 20+ connected gadgets can collectively draw as much as a small appliance. Over months, this adds up. Unplugging non-essential devices saves energy and extends device lifespan.
