10 Smart Home Gadgets Under $100 That Make Renting More Sustainable
Looking to make your rental more sustainable without breaking the bank or upsetting your landlord? Smart home gadgets are an affordable, renter-friendly way to reduce energy use, save money, and lower your environmental footprint. The best part? There’s no need for major installations or permanent changes—just smart, portable tech.
Below, you’ll find ten game-changing smart devices under $100. Each one is easy to install, safe for renters, and designed to make your home greener with minimal effort.
Why Smart Gadgets Matter for Sustainable Rentals
Traditional home upgrades can be expensive and often require modifying fixtures (not ideal if you rent). Smart home gadgets solve this problem:
- No drilling or rewiring: Most work via Wi-Fi, Bluetooth, or existing outlets.
- Portable: You can take them with you to your next place.
- Instant impact: Lower utility bills and reduce waste instantly.
Let’s jump into the top choices to make your rental—and lifestyle—more eco-friendly.
1. Smart Plugs: Control Energy Vampires
Smart plugs are one of the simplest and most versatile green upgrades for renters. They let you remotely turn devices on or off using your phone—or even set schedules, so devices never waste electricity while idle.
- Cut “phantom” power use from appliances and chargers.
- Create automations that match your routines.
- Enable voice controls with Amazon Alexa or Google Home.
Pro tip: Plug in your TV, gaming console, or any rarely-used appliance to save up to 10% on annual electricity costs!
2. Water Leak Sensors: Prevent Waste and Damage
Water damage and leaks waste natural resources and energy—and cost renters their deposits. Fortunately, wireless smart water leak detectors monitor high-risk areas and send instant alerts to your phone.
- Place them under sinks, behind toilets, or near washing machines.
- Many models work with no hub—just Wi-Fi and a smartphone app.
- Some even track humidity to help diagnose mold risk.
A little water awareness goes a long way in preserving resources and your rental deposit.
3. Smart LED Light Bulbs: Light Up Sustainability
Switching to LED light bulbs is already a huge energy saver—but smart LED bulbs take it a step further. These bulbs can be scheduled, dimmed, or programmed to turn off when you’re away.
- Compatible with most standard fixtures—no tools required.
- Set automation routines for evenings or out-of-town trips.
- 16 million colors for mood (or plant-friendly white light for indoor gardens).
Bonus: LEDs use up to 80% less energy than incandescents and can last for years, reducing both bills and waste.
4. Smart Power Strips: Smarter Than “Off”
Take energy savings further with a smart power strip. Unlike basic strips, smart versions let you automate, monitor, and individually control outlets—perfect for home offices, entertainment centers, or appliance clusters.
- Individually switch outlets remotely.
- Monitor each device’s real-time energy use.
- Enable voice or app control.
You’ll maximize savings and cut down on unnecessary electricity draw from every device, all in one spot.
5. Smart Thermostats (No Hardwiring!): Control Comfort Efficiently
Smart thermostats are often seen as a homeowner upgrade, but there are renter-friendly versions that require no hardwiring. Some models sit on a table or window ledge and work with portable A/C and space heaters.
- Control temperature via phone or voice assistant.
- Create heating/cooling schedules to save energy.
- Monitor real-time energy use for better budgeting.
Even a simple sensor can help you optimize your climate control—for comfort and lower emissions.
6. Smart Shower Heads: Track and Reduce Water Use
Smart shower heads are a surprising win for eco-minded renters. Many models track water flow, temperature, and time, giving you direct feedback to help cut shower times and overall water consumption.
- Monitor usage via built-in displays or Bluetooth apps.
- Water-saving aerators maintain great pressure with less waste.
- Easy to install; no plumbing experience needed.
With the average shower using over 17 gallons, trimming a few minutes adds up to significant savings for water, energy, and your utility bill.
7. Smart Window Sensors: Optimize Energy Use
Heating or cooling the outside is one of the most common ways renters waste energy. Smart window and door sensors let you know when someone leaves a window open, helping you maintain an efficient home climate.
- Receive alerts when a window is left open during A/C or heating.
- Integrate with other smart devices to adjust climate or lights automatically.
- Simple, adhesive installation; easy to relocate.
Small sensors = big efficiency boosts, especially in shared homes or apartments.
8. Smart Humidifiers and Air Quality Sensors
Good indoor air quality is vital for health and comfort, especially if city air is poor or windows are closed for efficiency. Today’s smart humidifiers and air quality monitors help you track and optimize your home’s environment.
- Measure pollutants (VOC, CO2, dust) and humidity in real time.
- Automate humidifier use or air purifiers based on actual needs.
- Most models are ultra-portable—perfect for renters.
Breathe easy and efficiently manage energy used for heating, cooling, and ventilation.
9. Smart Blinds or Curtain Controllers
Natural light is a free resource, but managing it isn’t always easy. Smart blind/curtain controllers let you schedule window coverings to reduce heat/cold loss or let in more sun—improving comfort and reducing HVAC use.
- Automate open/close times for maximum sunlight or shade.
- Some attach to your existing curtains—no drilling required.
- Integrate with smart thermostats or sensors for full eco-automation.
This upgrade requires a small investment but pays dividends in ease and energy savings.
10. Smart Recycling and Compost Bins
Recycling and composting are core to sustainable living, but actually remembering to do it properly can be a hassle. Smart bins use sensors and reminders to nudge you when it’s time to take out the trash or sort recycling.
- Integrated sensors prevent overflow and reduce contamination.
- Some models feature app-based tracking and reminders.
- Portable and renter-friendly: just plug in and set up the app.
Reduce waste, cut odor, and keep your rental sustainable—without a compost heap in the backyard!
Tips for Renters Using Smart Home Gadgets
- Check your lease: Most gadgets require no permanent changes, but avoid drilling or rewiring unless you have permission.
- Opt for plug-and-play devices: Choose tech that installs with adhesives, USB power, or standard plugs so you can bring it with you when you move.
- Secure your smart network: Protect your devices with strong, unique passwords and update firmware for security.
- Combine devices for maximum savings: Automate routines—like turning off lights and lowering blinds during the day—to amplify efficiency.
Short-Term Rental? No Problem!
If you’re in a short-term or furnished apartment, focus on smaller, ultra-portable gadgets (like smart plugs and lights) that won’t leave a trace when you leave. You’ll see monthly savings and make a positive impact—without investing in property you don’t own.
