10 Smart Home Gadgets Under $100 That Make Eco-Friendly Renting a Breeze

Living sustainably is easier — and more affordable — than ever before. Gone are the days when “smart home” tech meant expensive installations. Today, eco-conscious renters can optimize their homes with smart gadgets that require no permanent changes and won’t upset the landlord. Even better, these greener upgrades don’t have to break the bank.

Below you’ll find our top picks for smart home gadgets under $100 that streamline your eco-friendly journey as a renter. Each of these affordable devices can help you save energy, reduce waste, and enjoy a more comfortable living space — all with quick, non-invasive setup and simple removal when you move.

Why Smart Home Gadgets Are Perfect for Eco-Friendly Renters

• Portability: Take your investment with you when you move.
• No permanent installation: Most gadgets require no drilling, rewiring, or landlord approval.
• Immediate savings: Cut down on energy or water usage right away.
• Easy setup: Many devices are plug-and-play — no tech expertise required.

Let’s dive into the best smart gadgets every eco-minded renter should consider.

1. Smart LED Light Bulbs

Old incandescent bulbs waste energy and add to your electricity bill. Replace them with smart LED bulbs that use up to 80% less power and offer convenient features:

• Control from your phone via Wi-Fi or Bluetooth
• Set schedules so lights turn off automatically
• Adjust brightness or color temperature

Look for Energy Star rated models (such as Philips Hue or Wyze Bulb) for extra efficiency. These bulbs pay for themselves quickly through reduced utility costs.

Best Practices for Renters:

• Screw them into existing lamps or fixtures, and just take them out when you move.
• Use scenes like “All Off” before leaving for work to cut down on wasted electricity.

2. Smart Plugs

Many appliances keep sipping power even when off. Smart plugs let you schedule, automate, or remotely turn off electronics with your phone.

• Reduce phantom loads by cutting power to TVs, game consoles, coffee makers, and more
• Monitor usage with energy reporting features on select models
• Compact, renter-friendly size — just plug in and go

Best Practices for Renters:

• Set a “bedtime routine” to switch off all unnecessary devices at night.
• Pair with voice assistants for voice controls if you want extra hands-free convenience.

3. Smart Power Strips

Upgrade from a simple surge protector to a smart power strip. These offer:

• Individually controlled outlets so you can shut off only what you need
• App-based scheduling to power down appliances while you’re away
• Energy consumption tracking in real time (on select models)

Smart strips are great for clustered devices like entertainment centers, workstations, or charging hubs.

Best Practices for Renters:

• Mount to the wall with removable adhesive strips if needed — avoid drilling!
• Label outlets in the app for easy identification and control.

4. Programmable Smart Thermostats (No Wiring Required)

Smart thermostats aren’t just for homeowners — certain models are designed for renters, working with portable heaters, window A/C units, or plug-in systems.

• Remotely control temperature from your phone
• Set energy-saving schedules that adjust automatically when you’re home or away
• No C-wire or hardwiring necessary (look for plug-in or infrared models like Sensibo or Cielo Breez)

Best Practices for Renters:

• Choose models specifically made for plug-in or window units.
• Store old remotes in a safe place in case you need to revert settings for move-out.

5. Smart Water Leak Detectors

Even a small leak can waste hundreds of gallons and damage your rental property. Smart water leak sensors alert your phone the moment they detect moisture.

• Place under sinks, near hot water heaters, or behind toilets
• Battery-powered and portable — no installation required
• Peace of mind while traveling or away from home

Best Practices for Renters:

• Let your landlord know right away if a leak is detected — you’ll avoid costly disagreements and ensure quick fixes.
• Check batteries twice a year for reliable operation.

6. Smart Shower Heads

Traditional showers waste water and energy heating it. A smart shower head analyzes water usage and can gently nudge you to shorten your showers for bigger savings.

• Track real-time water and energy use via smartphone
• Visual timers or color indicators for shower durations
• No tools needed for installation — simply screw onto your existing pipe

Best Practices for Renters:

• Save your old shower head to swap back when you move out.
• Use built-in tracking to set personal goals (e.g. cut your showers by a few minutes each week).

7. Smart Window Sensors

Poorly sealed windows lead to lost heat or A/C. Smart window and door sensors help alert you when windows are left open or entry points are insecure — ideal for energy savings and peace of mind.

• Send notifications to your phone if a window is open when it shouldn’t be
• Activate smart routines like switching off HVAC while windows are open
• Install with removable adhesive strips — no tools required

Best Practices for Renters:

• Test placement before sticking sensors to ensure best signal and reliability.
• Pair with window insulation kits for additional efficiency.

8. Smart Blinds Controllers

Optimize daylight and indoor temperature by automating your blinds. Smart blinds controllers retrofit to existing blinds to open or close them according to a schedule, sunlight, or even weather conditions.

• No drilling or rewiring — most use adhesive or strap mounting
• Integrate with your phone, Alexa, or Google Assistant
• Prevent unwanted heat loss/gain by adjusting blinds automatically

Best Practices for Renters:

• Double-check your blinds’ size and type for compatibility.
• Use scheduled routines (like closing blinds at noon in summer) to keep cool without A/C.

9. Smart Air Quality Monitors

Indoor air pollution affects your health and how efficiently you heat or cool your space. Smart air quality monitors track humidity, VOCs, temperature, and even CO2 levels, helping you make healthier, greener choices.

• Monitor air quality trends over time
• Receive alerts when it’s time to ventilate or adjust your air purifier
• Portably placed — just plug in or use internal batteries

Best Practices for Renters:

• Position monitors away from vents for more accurate readings.
• Combine with smart fan or air purifier plugs for automatic air quality control.
