What is a Smart Thermostat?

Updated 2026-05-28

A smart thermostat is a climate control device that connects to the internet, allowing for remote management via a smartphone, tablet, or computer. These devices can learn guest preferences, adjust to local weather conditions, and be programmed with schedules to optimize energy consumption.

By providing remote access to a property's HVAC system, hosts can ensure the unit is comfortable upon guest arrival and that energy isn't wasted between stays.

How it works

A smart thermostat replaces a traditional thermostat and connects to the property's Wi-Fi network. Once installed and linked to a companion app, a property manager can set specific temperature schedules, such as lowering the heat after check-out or pre-cooling the unit before check-in.

This remote control capability can be integrated into broader property management systems for seamless automation; for instance, a check-out logged in a PMS platform like Lodgify could automatically trigger the thermostat to enter an energy-saving mode. Some models also use geofencing or motion sensors to detect occupancy and can provide energy usage reports to help hosts find opportunities for savings.

Why it matters

Smart thermostats offer significant advantages for vacation rental management by reducing energy costs, which are often one of the largest variable expenses for hosts. They also enhance the guest experience by ensuring a comfortable temperature upon arrival and providing easy-to-use controls.

For managers, the ability to remotely monitor and control the climate prevents energy waste, such as when guests leave the AC running after departure, directly protecting the property's profitability.

Examples

  • A property manager in Florida receives an alert that the AC in a vacant beach condo is running at 65°F. They use their smartphone to remotely raise the temperature to an energy-saving level.
  • A host of a ski chalet in Colorado sets their smart thermostat to warm the cabin to 70°F two hours before a guest's scheduled check-in, ensuring a cozy welcome.
  • After guests check out, a host's system automatically sets the thermostat to an 'away' mode, maintaining a baseline temperature that prevents pipes from freezing while saving significant energy.
  • A host sets a maximum cooling limit of 68°F and a maximum heating limit of 75°F on their smart thermostat, giving guests control within a reasonable range while preventing extreme energy use.

Frequently asked questions

Can a smart thermostat save money in a vacation rental?+
Yes, by preventing unnecessary heating or cooling when a property is vacant and by setting energy-efficient schedules, a smart thermostat can significantly reduce utility bills. The ability to remotely monitor and adjust settings ensures no energy is wasted between guest stays.
What is the difference between a smart thermostat and a programmable thermostat?+
While both can be scheduled, a smart thermostat connects to Wi-Fi, enabling remote control, learning capabilities, and integration with other smart home devices. A standard programmable thermostat only allows for setting schedules directly on the physical device.
Should vacation rental hosts give guests full control over the smart thermostat?+
It is common practice to allow guests to adjust the temperature within a reasonable range. Many smart thermostats allow hosts to set minimum and maximum temperature limits to prevent extreme settings that could drive up costs or strain the HVAC system.
Do I need a specific type of HVAC system to use a smart thermostat?+
Most modern smart thermostats are compatible with a wide variety of HVAC systems. It is crucial, however, to check the compatibility of a specific thermostat model with your property's heating and cooling system before purchasing and installing it.
