10 Smart Home Gadgets Under $100 That Make Rentals Greener and More Efficient

Making your rental home more eco-friendly doesn’t have to mean big renovations—or a big budget. Thanks to advancements in smart home tech, it’s easier than ever to boost energy efficiency, cut utility costs, and minimize environmental impact, all without drilling a single hole or violating your lease. This guide explores ten game-changing smart gadgets under $100 that eco-conscious renters can use to create greener, more efficient living spaces.

Why Smart Home Gadgets Matter for Renters

As a renter, you may feel limited in your ability to improve the sustainability of your living space. Permanent upgrades like solar panels or new windows are rarely feasible. That’s where affordable smart home devices come in. Most of these gadgets are:

Easy to install—usually plug-and-play or app-based
Non-invasive—no need for drilling or rewiring
Portable—take them with you to your next home
Universally compatible—work with most rental infrastructures

10 Smart Home Gadgets Under $100 for Greener Rentals

1. Smart Plugs: Outsmart Phantom Energy Use

Did you know that electronics and appliances can drain energy—even when turned off? Smart plugs kill “vampire power” by letting you control outlets right from your phone or with voice assistants like Alexa or Google Home.

Automate schedules for lamps, fans, or coffee makers
Switch devices off remotely to cut power when you’re away
Track energy consumption in real time

Estimated savings: Up to 10% off your electric bill.

2. Smart Thermostats: Intelligent Climate Control

Traditional thermostats are often wasteful. Smart thermostats (even renter-friendly plug-in or wireless models) learn your routines and optimize heating and cooling for comfort and efficiency.

Control temperature from anywhere with an app
Set geofencing—adjust temp as you come and go
Create custom schedules for different days

Bonus: Some models are battery-powered or adhesive, avoiding hardwiring.

3. LED Smart Bulbs: Bright Ideas for Savings

Replacing incandescent bulbs with LED smart bulbs slashes electricity use by up to 80%. With Wi-Fi/Bluetooth models, you get:

Remote control and voice activation
Customizable brightness/color for ambience or focus
Scheduling, grouping, and automation features

Pro tip: Take bulbs with you when you move!

4. Smart Power Strips: Targeted Power Management

Smart power strips go a step beyond ordinary surge protectors by letting you individually control or automate each connected device. Ideal for entertainment centers, home offices, and kitchen counters.

Timer and app control for each outlet
Monitor device-by-device power usage
Cut power to idle electronics automatically

5. Smart Water Leak Sensors: Prevent Waste and Damage

Rental properties often have hidden leaks that waste water and cause pricey damage. Smart leak detectors are small, battery-powered, and stick easily under sinks, behind washers, or near water heaters.

Instant smartphone alerts for drips or floods
Helps conserve water and avoid costly repairs
Essential for high-rise rentals or older buildings

6. Smart Window Sensors: Savings with Simple Monitoring

Window and door sensors aren’t just for security—they let you monitor when windows are left open, which can drastically affect heating or cooling bills.

Get notifications if a window/door is left ajar
Integrate with smart thermostats to pause heating/cooling
Battery-operated and peel-and-stick; easy removal for moving out

7. Smart Shower Heads: Monitor Water & Energy Use

Smart shower heads track water consumption, set usage goals, and sometimes even change color to warn you when it’s time to finish up. No plumber required!

Real-time feedback on water usage
Helps cut both water and heating bills
Simple to install on most standard showers

Combine with low-flow settings for maximum impact.

8. Smart Radiator Thermostats: Control Heat Room-by-Room

If your rental has radiator heating, smart radiator thermostats are a true game changer. These battery-powered devices attach to traditional radiators, offering precise control over each room.

Set schedules by room or zone
Remote adjustment via mobile app
Reduce heating costs and energy waste

No central thermostat needed—perfect for older apartments.

9. Smart Blinds Controllers: Automated Sunlight Management

Smart blinds controllers motorize your existing blinds and automate opening/closing based on time, temperature, or sunlight. This reduces thermal loss in winter and blocks heat in summer.

Install in minutes—no holes or wires
Schedule to match your daily routine
Reduce HVAC demand by blocking or letting in sunlight as needed

Choose models with solar charging for extra efficiency.

10. Smart Air Quality Monitors: Breathe Cleaner, Smarter

Reducing energy use is great, but a healthy indoor environment matters, too. Smart indoor air quality monitors track pollutants, humidity, and CO2. They provide actionable tips or even soothe allergies by prompting you to open a window or run a purifier only when needed.

Receive alerts when air quality drops
Track trends over time and identify pollution sources
Some models sync with other smart devices for automation

How to Choose the Right Smart Gadgets for Your Rental

Before diving into smart home upgrades, keep these renter-friendly tips in mind:

Prioritize portability: Choose devices that can move with you.
Seek non-permanent installation: Favor stick-on, plug-in, or otherwise non-invasive gadgets.
Check compatibility: Ensure the devices work with your current Wi-Fi and smart ecosystems (Alexa, Google, Apple, etc.).
Batch for savings: Starter kits or multi-device packs often cost less per unit.
Inform your landlord: While most smart gadgets are temporary, it’s smart to keep landlords in the loop about device use and removability.

Maximizing Impact: Bundle Gadgets for Greater Savings

Many smart home devices work even better together. Consider these bundled strategies:

Smart thermostats + window sensors: Automatically pause heating or cooling if a window is open.
Smart plugs + LED bulbs: Control all lighting from one app and track savings.
Leak sensors + smart plugs: If a leak is detected near a washing machine, automatically cut power to prevent hazards.

Installation Tips for Renters

No tools needed: Most smart gadgets designed for renters use adhesives, suction cups, or simple screw-on attachments.
Label your devices: Especially useful for smart plugs and bulbs when moving or resetting.
Set up device groups/scenes: Use your smart home app to group devices by room or activity to simplify control.
Use surge protectors and cable organizers: Keep things tidy and protect your investment.
