10 Smart Home Gadgets Under $100 That Make Renting More Sustainable

Sustainable living isn’t just for homeowners with big solar panels and sprawling gardens. Renters can take plenty of action, too—especially with affordable smart home gadgets that boost energy efficiency, reduce waste, and make eco-friendly living easier than ever. The best part? You don’t need to spend a fortune to make a difference.

Below, discover 10 smart home devices under $100 that are renter-friendly, effective, and simple to install or pack up at move-out. Let’s explore how these tech tweaks can minimize your footprint—and your bills.

1. Smart Plugs: Stop Phantom Energy Loss

“Vampire” or standby power is when electronics draw electricity even when turned off. Smart plugs are an effortless solution for renters who want to cut down on wasted energy.

How Smart Plugs Help Renters

• Remote control: Schedule on/off times from your phone so devices don’t run all day.
• Monitor usage: Some smart plugs track real-time energy use, helping you identify energy hogs.
• No installation: Just plug them into a standard outlet—perfect for rental properties.

Tip: Use smart plugs for high-drain devices like space heaters, coffee makers, and entertainment centers.

2. LED Smart Bulbs: Light the Way to Efficiency

Swapping out regular bulbs for LED smart bulbs is one of the cheapest and quickest sustainability upgrades you can make. These bulbs use a fraction of the energy and last far longer than traditional options.

Benefits for Renters

• Adjust brightness and color: Match lighting to your needs or mood with a simple app or voice command.
• Schedule and automation: Never worry about accidentally leaving lights on.
• Energy savings: LEDs use up to 80% less power than incandescents.
• Easy to swap back: Take your bulbs with you when you move out.

3. Smart Power Strips: Tame Multiple Devices

For renters with entertainment set-ups or home offices, smart power strips offer extra control and efficiency compared to standard extension cords.

Key Features

• Individual outlet control: Turn off specific devices remotely without unplugging everything.
• Overload protection: Safeguards against power surges, extending device life.
• Energy monitoring: Track total usage for groups of appliances.

Swap out a traditional power strip for a smart version and start managing “phantom loads” with ease.

4. Smart Thermostats for AC Units

Most renters can’t replace wall thermostats, but if you have a window or portable AC unit, you’re in luck. Smart AC controllers plug into your AC unit and let you control the temperature using your phone.

Why Renters Love It

• Custom scheduling: Cool the room before you get home—save energy when it’s empty.
• Geo-fencing: Some models adjust settings when you leave or return, maximizing efficiency.
• No permanent installation: Just unplug and take the controller with you when you move.

These gadgets help reduce energy waste, keep bills low, and stay rental-friendly.

5. Leak Detectors: Prevent Water Waste (and Damage)

Leaky pipes and faucets waste thousands of gallons of water every year. Smart leak detectors can alert you to trouble before a minor drip becomes a flood—or a mark on your security deposit.

Top Features

• Real-time alerts: Get smartphone notifications the moment a leak is detected.
• Easy placement: Stick them under sinks, water heaters, washing machines, or anywhere leaks are likely.
• No plumbing skills required: Totally tool-free installation for renters.

Pro tip: Notify your landlord immediately if you detect a leak—prevent wasted water and costly property damage.

6. Smart Water Usage Monitors

If your rental has its own water meter (or for specific appliances like showers), smart water monitors can help you understand your usage and change habits to conserve more.

Water-Saving Advantages

• Track use in real-time: Find out exactly how much water you’re using, right on your phone.
• Goal setting: Challenge yourself to shorter showers or fewer laundry loads and watch your progress.
• Leak detection: Spot hidden leaks by watching for unexpected spikes in usage.

Most water monitors attach quickly without any need to alter pipes—perfect for renters who want insight, not renovation headaches.

7. Smart Blinds or Curtain Controllers

Natural light can be a massive energy saver. Smart blind controllers automate your shades to keep rooms cool in summer and warm in winter.

How They Boost Sustainability

• Automated schedules: Open blinds to let in winter sun, close them during summer heat.
• Integration with weather triggers: Some models adjust blinds based on outside conditions.
• No drilling or hardwiring: Most smart controllers retrofit existing blinds or curtains in minutes.

You’ll cut HVAC use and make your apartment more comfortable year-round.

8. Smart Shower Timers

Water usage in showers can be sky-high. A smart shower timer helps you stick to shorter, more efficient routines.

Sustainable Perks

• Customizable alerts: Get notified when it’s time to finish up.
• Waterproof displays: Some timers use LED lights or audio cues right in your shower.
• Monitor habits: Use the data to challenge yourself or roommates to save more.

Easy to install and remove—just stick them to the shower wall or hang from the showerhead.

9. Indoor Air Quality Monitors

An efficient home is a healthy one. Smart air quality monitors keep tabs on VOCs, CO₂, humidity, and more—helping you act before issues escalate.

Why It Matters for Renters

• Data-driven insights: Find out when it’s time to open windows, run a fan, or address mold risks.
• Portable: These monitors can go from rental to rental.
• Peace of mind: Keep your living space healthy, even in older buildings.

Look for monitors with smartphone alerts or Alexa/Google compatibility for added convenience.

10. Smart Recycle and Compost Reminders

Recycling and composting can be inconsistent in rental properties—but smart tech is here to help keep you on track.

How These Gadgets Work

• Reminder systems: Set scheduled alerts for trash, recycling, and compost days.
• Smart bins: Some have weight sensors or QR codes to ensure proper sorting and reduce contamination.
• App integration: Learn local recycling rules or track your landfill diversion on your phone.

Even simple motion-sensor bins can boost recycling by making it easier for you and guests to do the right thing.

Tips for Smart Gadget Use in Rentals

Choose Portable and Non-Invasive Devices

• Look for plug-in or battery-powered gadgets that don’t require drilling or rewiring.
• Stick-on options or tabletop sensors are easiest to remove without damaging walls or fixtures.

Get Landlord Approval (When Needed)

• Devices that change wiring (like thermostats) may require approval. Many of these gadgets avoid permanent installation, making landlord consent unnecessary.
• Always read your lease to stay compliant and protect your security deposit.
