7 Smart Home Gadgets Under $100 That Instantly Boost Energy Efficiency in Rentals
Energy efficiency isn’t just for homeowners anymore! If you’re renting, there are plenty of affordable smart gadgets that make it easy to save energy, lower bills, and reduce your environmental impact. The best part? Most can be installed without tools or permanent changes, making them renter-friendly. Here’s a look at seven smart home gadgets under $100 that offer instant energy savings for apartments, condos, and rental homes.
Why Smart Home Gadgets Are Perfect for Renters
Moving often or dealing with landlord rules doesn’t have to keep you from enjoying the benefits of smart home technology. Today’s affordable gadgets are:
- Portable: Most devices are wireless and can move with you.
- Non-invasive: No hardwiring or drilling required.
- Easy to use: Intuitive apps and integrations minimize learning curves.
- Energy-efficient: Small changes add up to big utility savings, even if you can’t replace appliances.
1. Smart Plugs: Eliminate Energy Vampires Easily
Smart plugs are a renter’s secret weapon for cutting “phantom” energy usage—power that devices draw even when they’re turned off. Simply plug them into an outlet, connect your appliance, and control power with your phone or voice assistant.
Key Energy-Saving Features
- Scheduled power: Automatically turn off gadgets when not in use.
- Remote access: Forgot to turn off the fan or TV? Shut them off from anywhere.
- Energy monitoring: Some models track how much electricity each device uses.
Best For:
- Lamps and lighting
- Fans and space heaters
- Chargers
- Entertainment systems
Installation: Just plug and play—no need to call your landlord!
2. Smart Thermostats (No Hardwiring Required)
Traditional thermostats often require wiring, which can get tricky in rentals. But new battery-powered or plug-in smart thermostats work with portable heaters and A/C units—no electrician required.
How They Save Energy
- Precise temperature control: Avoid overheating or overcooling your space.
- Scheduling: Set heating/cooling to match your daily routine.
- Remote adjustments: Control via your smartphone from anywhere.
Perfect For:
- Window A/C units
- Portable heaters
- Radiant heaters
Note: Always check compatibility with your appliances before buying.
3. Smart LED Bulbs: Cut Lighting Costs Instantly
Swapping standard bulbs for smart LED bulbs is one of the quickest ways to lower your utility bill. LEDs use up to 80% less energy and last much longer than incandescents.
Top Benefits
- Dimming: Reduce brightness to save even more energy.
- Scheduling: Automate when lights turn on/off.
- Remote control: Never worry about leaving lights on by accident.
Smart bulbs fit into standard sockets, so they’re perfect for any rental. Take them when you move!
4. Energy Monitoring Smart Power Strips
If you have a cluster of electronics—think TV setups, gaming consoles, or a work desk—an energy monitoring smart power strip is ideal. These strips control several devices at once and measure real-time electricity usage for each outlet.
Features for Renters
- Individually controlled outlets: Customize which devices power down.
- Energy reports: Identify which gadgets eat up the most electricity.
- Automated schedules: Set everything to shut off overnight or when you’re away.
Best Use Cases
- Entertainment centers
- Home office equipment
- Kitchen gadgets
Plus, surge protection keeps your electronics safe!
5. Smart Window Sensors: Maximize Heating and Cooling Efficiency
Heating or cooling a space with cracked windows wastes energy fast. Smart window sensors alert you when a window is left open, allowing you to respond before energy escapes.
Renter-Friendly Features
- Easy installation: Most attach with adhesive (no drilling or tools).
- Mobile alerts: Get notifications if a window is open while HVAC is running.
- Integration: Some can pause your smart thermostat or send reminders.
Ideal For:
- Urban apartments prone to drafts
- Family homes with kids who forget to close windows
They’re small, subtle, and move with you when your lease ends.
6. Smart Radiator Valves (For Hot Water Radiators)
Renting in an older building with radiator heating? Smart radiator valves replace existing manual valves, giving you digital temperature control—without touching the boiler or central system.
Features That Save Energy
- Custom heating schedules: Warm rooms only when needed.
- Room-by-room control: Avoid overheating unused spaces.
- Quick installation: Most twist on by hand (no tools or plumber needed).
Check that your radiator valve is compatible—most UK/European-style hot water radiators are, but ask your landlord if unsure.
7. Smart Ceiling Fan Switches (No Wiring Needed)
Ceiling fans are a cost-effective way to cool (and even heat) your space, but it’s easy to forget to turn them off. Battery-powered smart fan switches let you adjust speeds, set schedules, and power off remotely—all without touching existing wiring.
Energy Efficiency Benefits
- Remote on/off: Kill the fan when you leave, from bed or while away.
- Custom routines: Run fans only during peak hours.
- Battery installation: Attach over old switch or use included adhesive—no landlord approval required.
This is a perfect upgrade for older rentals where ceiling fans lack remote controls!
Bonus Tips for Green Rental Living
- Talk to your landlord: Many property managers encourage energy-saving upgrades—some will even share the cost!
- Keep receipts and boxes: Smart gadgets are portable, so take them when you leave.
- Integrate with voice assistants: Connect devices to Alexa, Google Home, or Apple HomeKit for maximum convenience.
- Monitor your savings: Use gadget energy reports or utility apps to see your progress.
