Smart Home Devices for STR: Locks, Thermostats & Monitoring
Transform your short-term rental operations with smart technology. From keyless entry to noise monitoring, learn which devices deliver real ROI for vacation rental investors.
Smart home technology has evolved from luxury novelty to operational necessity for serious STR operators. The right devices save hours of time per month, reduce energy costs, prevent problems before they become emergencies, and create the seamless guest experiences that earn five-star reviews. For more on creating memorable stays, check out our Guest Experience Optimization Guide.
But the smart home market is crowded with options, and not every consumer device works well in a vacation rental context. STR properties have unique requirements: devices must work reliably without your presence, tolerate abuse from unfamiliar users, integrate with property management systems, and operate without depending on guest assistance.
This guide evaluates smart home technology specifically for STR applications, covering what to buy, what to avoid, and how to implement an effective smart home strategy for your properties.
Smart Locks: The Foundation of STR Technology
If you implement only one smart device category, make it locks. Smart locks eliminate key management headaches, enable flexible check-in times, and provide access logs that enhance security and accountability.
Why Smart Locks Matter for STRs
- No Key Exchanges: Eliminate the logistics of meeting guests, hiding keys, or changing locks when keys are lost.
- Unique Codes Per Guest: Generate temporary codes that automatically expire at checkout, enhancing security.
- Flexible Check-In: Guests can arrive at their convenience without coordinating with you or a property manager.
- Access Logs: Know exactly when guests arrived, when cleaners accessed the property, and detect any unauthorized entries.
- Emergency Access: Grant temporary access to maintenance workers or emergency responders remotely.

Smart Thermostats: Comfort and Savings
Smart thermostats deliver dual benefits: improved guest comfort through better climate control and significant energy savings through intelligent scheduling and remote management.
STR-Specific Thermostat Requirements
- Remote Access: Adjust temperatures from anywhere, whether pre-cooling before arrival or adjusting for a guest complaint.
- Temperature Limits: Prevent guests from setting extreme temperatures that waste energy or strain HVAC systems.
- Occupancy Detection: Automatically adjust when property is unoccupied between guests.

Temperature Management Strategy
Effective thermostat management for STRs requires thinking through different scenarios:
- Between Guests: Set to energy-saving mode (78F summer, 62F winter) to reduce costs while preventing extreme conditions.
- Pre-Arrival: Schedule comfort temperatures (72F) to begin 2-3 hours before check-in.
- During Stay: Allow guest control within limits (66-76F) to balance comfort with efficiency.
- Post-Checkout: Return to energy-saving mode once checkout time passes.
Noise Monitoring: Protecting Your Property
Noise complaints are among the most common neighbor issues for STR operators and can threaten your ability to operate, especially in areas with noise ordinances or HOA restrictions. Noise monitors provide early warning of parties or disturbances.
How Noise Monitors Work
Privacy-compliant noise monitors measure sound levels (decibels) without recording audio. They alert you when sustained noise exceeds thresholds, allowing intervention before neighbors complain or police are called.
- Decibel Monitoring: Track noise levels throughout the property.
- Customizable Thresholds: Set alert levels appropriate for your property and neighborhood.
- Duration Triggers: Avoid false alarms by requiring sustained noise levels before alerting.
- Time-Based Rules: Different thresholds for daytime versus quiet hours.
- Automated Guest Messaging: Some systems can automatically send warnings to guests.
