Smart home for vacation rentals: three building blocks that pay off, and what you can skip.
A smart lock, a radiator thermostat and the check-out sign you print yourself as an A4 PDF (included in the CheckYout subscription): these are the three smart-home pieces that actually pay off for vacation rental hosts. The other devices that keep being recommended deserve a closer look, and some of them you can skip.
Why Smart Home for Vacation Rentals?
As a vacation rental host, you're rarely on-site. Yet you still need to know what's happening at your property: Has the guest checked out? Is the heating running unnecessarily? Is the door locked? Smart home devices give you this information in real time, without having to be there.
The difference from a regular smart home: in a vacation rental the guests change constantly, and nobody should have to install an app or read a manual just to turn on the heating. Whatever you set up has to run on its own.
Smart Door Lock: No Key to Hand Over
A smart door lock like Nuki solves one of the biggest problems for hosts: the key handover. Instead of lockboxes, meeting points, or hidden keys, each guest receives a temporary access code.
Benefits for hosts:
- ✓ No more lost keys
- ✓ Access codes expire automatically
- ✓ See in your dashboard when someone opens the door
- ✓ Your cleaning team gets their own code
Pro tip: With CheckYout + Nuki, you automatically see when your cleaner arrives and when they finish. The access code is simply linked to the cleaning profile.
Cost: You buy the Nuki Smart Lock separately. Connecting it to CheckYout runs on the Smart Home add-on (CHF 9.90 per month), which unlocks every smart-home integration.
Smart Thermostat: Cut Heating Costs Without Sacrificing Comfort
Between bookings, the heating often runs at full power unnecessarily. A smart thermostat like tado° automatically lowers the temperature after check-out and heats back up in time for the next arrival. If the next arrival is booked for the same day, it simply stays at comfort temperature.
What does this mean in practice?
- ✓ Automatic temperature reduction after check-out (e.g. from 21°C to 15°C) – unless a new arrival is booked the same day
- ✓ Timely pre-heating before the next arrival
- ✓ No more fully heated apartment on the days between guests
- ✓ How much you save depends on vacancy, insulation, and energy prices
Pro tip: The tado° integration with CheckYout makes this fully automatic: guest checks out → heating goes down (unless a new arrival is scheduled the same day). Next booking in Smoobu → heating goes back up in time.
Cost: You buy the thermostats separately, one per room. Connecting them to CheckYout runs on the Smart Home add-on.
Check-out Automation: The Part Almost Nobody Thinks Of
Most hosts think of hardware when they hear smart home: locks, thermostats, cameras. But the biggest time savings often come from software: automatic check-out notifications.
The problem: your cleaning team doesn't know when the guest has actually left. Many guests depart earlier than planned without letting anyone know. Your team waits. Or you send an awkward morning message.
The solution: a check-out sign with a QR code. The guest scans it when leaving, confirms the check-out, and your team instantly receives a WhatsApp message. That saves you the morning coordination routine.
What you gain:
- ✓ Your team hears about the check-out as soon as the guest scans, even when that is before the scheduled check-out time
- ✓ No more manual coordination
- ✓ Guests see a reminder checklist (keys, windows, trash)
- ✓ Automatic Google review request right at check-out
What is only worth it in some cases
Not every smart home device makes sense for a vacation rental:
- Smart speakers (Alexa, Google Home): Privacy concerns for guests, complicated setup, and barely any value for the host.
- Smart lighting: Not a must as guest comfort, guests can find the light switch. It becomes useful when the lights go off by themselves after departure: with Philips Hue, CheckYout switches the lights off at check-out.
- Indoor surveillance cameras: Absolute no-go in vacation rentals. Violates guest privacy and is illegal in many countries.
- Smart plugs: Useful for specific appliances such as the boiler: with Shelly, CheckYout switches them off at check-out.
Rule of thumb: Invest in devices that save you time or reduce costs as a host, not in gimmicks for the guest.
Smart home and CheckYout working together
The three building blocks we would start with:
- CheckYout Check-out Sign – Cleaning-team notifications, Google reviews, reminder checklist. Included in the CheckYout plan, with a 14-day free trial.
- Nuki Smart Lock – Keyless handover, cleaning tracking, security.
- tado° Smart Thermostat – Reduce heating costs, automatic temperature management.
All three feed into each other: guest checks out → team gets notified → heating goes down (unless a new arrival is scheduled the same day) → cleaning is tracked → heating goes back up before the next arrival – all automatically.
Where to Start
Smart home marketing loves features. For vacation rentals, a different question matters: what saves you time or money every weekend as a host? Invest with that in mind and you'll get away with three things: door lock, thermostat, and checkout signal.
The most important thing: your guests shouldn't even notice the technology. Everything runs in the background, for you as the host.
