10 Smart Home Gadgets That Save Energy (and Your Security Deposit)

Living in a rental shouldn’t keep you from upgrading your space with smart tech that conserves energy and helps you keep that hard-earned security deposit. The latest wave of renters-friendly smart home gadgets are easy to install and undo, energy efficient, and make your apartment feel like the future. Read on for our expert picks and tips on making your home greener — with zero holes in the wall required!

Why Energy-Saving Smart Gadgets Are Perfect for Renters

Most eco-friendly upgrades can seem out of reach for renters, especially when landlords are wary of permanent changes. Thankfully, today’s smart home gadgets offer:

• No-drill installation: Most devices attach with adhesive or replace easily when you move out.
• Remote controls: Manage your home’s energy use from your phone.
• Low-cost fixes: No need to replace wiring or appliances.
• Deposit-friendly: Remove everything before you leave—no trace, no penalty!

Let’s dive into the top 10 smart home gadgets for renters that help slash energy bills while safeguarding your deposit.

1. Smart Plugs: Turn Anything Into a Smart Device

Many everyday devices—like lamps, fans, or your coffee machine—consume energy even when “off.” Smart plugs give you full control with scheduling and remote shut off, so nothing stays on when you’re away.

How Smart Plugs Save You Energy (and Hassle)

• Set schedules, timers, or automation rules.
• Monitor energy consumption for each plugged-in device.
• Control appliances via app or voice (Alexa, Google, Siri compatibility).
• No wiring required: Just plug in and connect.

Quick Renter Tip

Before moving out, simply remove the smart plug—no permanent changes made.

2. Smart Thermostats: Comfort & Efficiency, No Wires Needed

Traditional thermostats need wiring, but renters have wireless alternatives. New smart thermostats offer:

• Easy-to-install: No screws or rewiring apartments.
• Room-by-room temperature and scheduling control.
• Auto-adjustment for sleep or away modes.
• Remote control from your phone (great for travel or unpredictable schedules).

Important Renter Considerations

Many smart thermostats now come with adhesive wall mounts or simply sit on a table. Always check with your landlord if you need to replace an existing hardwired thermostat—wireless ones are usually fair game.

3. Smart Light Bulbs & Switches: Brighter Savings

LED bulbs are already energy-savers. Smart bulbs and switches take things further, letting you:

• Dim or schedule lights anywhere—reduce accidental “left on” waste.
• Change color temperatures for comfort and productivity.
• Group bulbs by room in the app for quick control.
• Set lights to turn off when you leave (geo-fencing).

Perfect for Renters

All you do is swap out the bulb or add a switch cover. No electrical expertise required—replace with the landlord’s original bulbs before moving out.

4. Smart Power Strips: Eliminate Hidden Vampire Loads

Did you know electronics like TV, gaming consoles, and printers can use power even when off? Smart power strips let you:

• Turn off multiple devices with one tap.
• Set “master” and “slave” outlets—turn off accessories when the main device powers down.
• Monitor real-time energy use in the connected app.

Easy to unplug and go, smart strips are a non-permanent energy win for renters.

5. Smart Window Shades: Let the Light (and Savings) In

Heating and cooling are a renter’s biggest energy drains. Smart window shades open or close automatically, optimizing natural light:

• Block sun during peak heat for instant cooling efficiency.
• Let in warmth during winter morning hours.
• Control with your phone or set daily routines.

Adhesive, No-Drill Options

Look for self-adhesive or tension rod models that are installation- and landlord-friendly. Remove them (no marks) before moving out.

6. Water Leak Sensors: Stop Wasting Water (and Prevent Damage)

Even a small leak can spike your water bill—and if it causes damage, you risk your security deposit. Smart leak sensors give you an instant heads-up:

• Place battery-powered sensors under sinks, appliances, or radiators.
• Receive instant phone alerts if moisture is detected.
• No installation: Just set them on the floor and connect to WiFi.

Avoid the nightmare (and cost) of unnoticed drips and floods.

7. Smart Motion Sensors: Automate Lights and Save Power

Forgot to turn off the lights? Smart motion sensors handle it for you:

• Set entryway, hallway, or bathroom lights to turn on when you enter—and off when you leave.
• Avoid wasted power in high-traffic spaces.
• Battery operated (stick-and-go installation).

Perfect for forgetful roommates or families with kids!

8. Smart Radiator Valves: Precision Heating for Every Room

If your rental uses radiators, a smart valve can let you fine-tune temperatures and cut heating costs—without replacing the entire system:

• Replace existing radiator knob (tool-free models available).
• Program temperature schedules by time of day and room.
• Control via app or voice assistant.

No Permanent Alteration

The original knob can be swapped back when your lease is up.

9. Smart Showerheads: Save Water, Energy, and Money

Heating water is expensive, but you can cut costs with a smart showerhead that tracks water use (and even gives you feedback on time spent):

• LED indicators for optimal shower time.
• Some models display water temperature or usage.
• Easy to install—just unscrew old showerhead, screw on new one.

No plumbing skills needed and easy to remove when you leave.

10. Smart Door Sensors: Security and Energy Efficiency

Smart door/window sensors do more than alert you to break-ins. They can communicate with your other smart devices to help save energy:

• Set up rules: When the window is open, the smart thermostat or AC turns off automatically.
• Get alerts if you forget to close a door or window (great for ground-level units).
• Tiny and removable—adhesive-backed, with no drilling required.

Combine with smart plugs, lights, and thermostats for a super-efficient system—all deposit-friendly.

How to Choose the Right Smart Gadgets as a Renter

Before you invest, keep these renter-savvy tips in mind:

• Portable is key: Opt for plug-in, battery-powered, or adhesive-backed models.
• WiFi, not wires: Avoid gadgets that require hardwiring or permanent installation.
• Check with your landlord: Especially for anything that replaces an existing fixture.
• Plan for move-out: Save all packaging and instructions to reinstall the original item.

Smart Home Automation Hubs: Worth It?

If you choose multiple smart gadgets, an automation hub (like Amazon Echo, Google Nest, or Apple HomeKit) can bring them all together for seamless control. Just remember, pick a hub that doesn’t require permanent installation or modifications.

Maximizing Savings: How to Get the Most from Your Smart Gadgets

• Automate routines: Schedule temperature, lighting, and plug controls based on daily patterns.
• Create scenes: “Away mode” switches off all non-essential devices in one tap.
• Share access: Give roommates or family members control from their phones, too.
