5 Smart Home Gadgets Under $100 That Save Energy (and Your Security Deposit)
Renters face a unique challenge: enjoying the comfort and savings of a smart home, without risking damage to the property or violating lease agreements. Good news! Smart home tech is more affordable—and renter-friendly—than ever. You don’t need to shell out tons of cash or drill holes to gain better control over your energy use. In this guide, we’ll highlight five powerful—and portable—gadgets under $100 that help lower utility bills and protect your deposit.
Why Go Smart in a Rental?
Landlords love a unit that’s well cared for—but they may get nervous about holes in walls, hardwired devices, or systems they can’t control. That means renters must find tech solutions that are:
- Easy to install & remove
- Non-permanent (no drilling, wiring, or major modifications)
- Cost-effective
- Flexible for move-out
- Compatible with all skill levels
The five gadgets below check all these boxes—keeping you green, comfortable, and in your landlord’s good graces.
#1: Smart Plugs: The Easiest Energy-Saving Win
What Are Smart Plugs?
Smart plugs are Wi-Fi-enabled adapters that fit between ordinary appliances and your outlet. They allow you to control any plugged-in device remotely using an app or voice assistant (like Alexa or Google Home).
Power-Saving Benefits
- Eliminate phantom loads: Some electronics drain power 24/7 just by being plugged in. A smart plug cuts all power when off.
- Schedule usage: Automate on/off times for coffee makers, lamps, fans, or TV—never leave things running all day again.
- Avoid overheating: Some smart plugs monitor energy use and warn you of potential fire risks or device malfunctions.
Renter-Friendly Features
- No wiring or installation
- Zero risk of wall damage
- Simply unplug and take it with you when you move
How To Use Smart Plugs
- Plug in high-standby appliances: TVs, game consoles, computers
- Create morning/evening routines: automate lighting and fans based on your work schedule
- Monitor energy hogs: see what costs most—and cut their usage
Price Range: $10–$40 per plug, often less when bought in packs.
#2: Smart Bulbs: Customizable, Efficient Lighting
What Are Smart Bulbs?
Smart LED bulbs replace your standard bulbs and connect via Wi-Fi or Bluetooth. They let you control lighting color, brightness, and power from your phone or smart home assistant.
Power-Saving Benefits
- Use up to 80% less energy than old incandescent bulbs
- Automation: Set schedules so lights aren’t accidentally left on
- Remote control: Turn lights off when you leave home—even if you forgot
- Long lifespan: LEDs can last over 10 years, slashing replacement costs
Renter-Friendly Features
- No wiring—just swap bulbs
- Fits standard screw-base sockets (E26/E27)
- Take them with you or switch back to old bulbs when you move out
How To Use Smart Bulbs
- Replace bulbs in the most-used rooms: living room, bedroom, desk lamps
- Pair with smart plugs for extra control
- Create lighting “scenes” for reading, relaxation, or parties
Price Range: $10–$25 per bulb, with affordable starter packs available.
#3: Smart Thermostats for Renters: Affordable Climate Control
What Are Smart Thermostats for Renters?
Traditional smart thermostats need to be hardwired, which isn’t always permitted in rentals. Fortunately, several new models require nothing more than a plug, a battery, or a simple snap-on installation over your existing controls.
Power-Saving Benefits
- Easy temperature adjustments: Keep your home just comfortable enough and cut wasteful heating/cooling
- Scheduling: Avoid paying to cool or heat an empty apartment
- Receive usage reports highlighting savings opportunities
Renter-Friendly Features
- Models that fit over existing dials (like for baseboard heaters or window ACs)
- Battery-powered wireless options—no need to touch HVAC wiring
- Simple, reversible installation
How To Use Smart Thermostats for Renters
- Upgrade small spaces: control room heaters/ACs more precisely
- Pair with voice assistants for hands-free temp adjustments
- Use geo-fencing to trigger heating/cooling as you arrive or leave
Price Range: $40–$99. Look for “heat-and-cool” smart plugs, snap-on AC controls, and room thermostats made specifically for renters.
#4: Smart Switches & Dimmers: Retrofit Control Without Wiring
What Are Smart Switches & Dimmers?
You don’t have to rewire your walls to automate light switches. Battery-powered smart switches and stick-on dimmers give you control over existing lights—often without even swapping a single bulb.
Power-Saving Benefits
- Quickly turn off forgotten lights: Place extra switches near doors or bedside tables
- Dim lights: Save energy (and set the mood!) by reducing brightness
- Remote & voice control: Never cross the room just to shut off a light
Renter-Friendly Features
- No-wiring adhesive installation
- Attach to walls or furniture; easily remove without residue
- Works with most smart bulbs or switches; check for compatibility
How To Use Smart Switches & Dimmers
- Put a switch by your bedside to control overhead lights without getting up
- Add a stick-on dimmer to tricky rooms (like bathrooms)
- Pair with other smart devices for routines and automations
Price Range: $20–$50 per switch. Look for battery-powered or adhesive options designed for renters.
#5: Smart Sensors: The “Invisible” Energy Saver
What Are Smart Sensors?
Smart motion, door/window, and ambient sensors are tiny wireless devices that trigger other smart products based on movement, light, or temperature. They take your automation—and savings—to the next level.
Power-Saving Benefits
- Lights on only when needed: Motion sensors in halls, entryways, or closets mean never leaving lights on by accident
- Monitor open windows or doors: Cut heating/cooling waste by getting an instant alert or shutting off the system automatically
- Optimize heating/cooling: Use ambient sensors to fine-tune temperature in rooms you actually use
Renter-Friendly Features
- Small size, usually battery-powered
- Stick-on or portable—no damage to your rental
- Easy to relocate or pack up when you move
How To Use Smart Sensors
- Place motion sensors where lights are often forgotten (closets, laundry rooms, entryways)
- Put a window sensor on AC units to turn them off if a window is open
- Set up routines: e.g., if no one is home, turn off all lights and non-essential appliances
