Owen Bradley A house left alone for two weeks is a house with nobody to notice the small problems. A dripping washing machine hose, a heating system stuck at holiday temperature, or a package sitting on the porch for nine days all cost money or invite trouble. A proper smart home vacation setup solves those problems in about ninety minutes of preparation, and it does something a timer switch never could: it tells you what is happening while you are away and gives you a way to respond. This checklist walks through everything worth configuring before you lock the door, in the order that matters most.
Start With a Realistic Risk List
Before touching a single app, write down what could actually go wrong in your specific home. For most households the list is short: water damage from a burst supply line or failed appliance, a heating or cooling failure that lets pipes freeze or humidity spike, a break-in through an unwatched entry point, and a power cut that silently disables everything else. Each of those has a cheap, well-understood countermeasure.
Ranking the risks stops you from over-buying. A ground-floor apartment with no plumbing on outside walls needs very different preparation from a detached house with a basement and an old water heater. Spend your budget where the failure would be expensive and slow to detect, not where the gadget is most fun to install.
What to Prepare a Week in Advance
- Update firmware on every hub, camera, lock, and thermostat, then reboot each one so the update settles while you are still home to fix problems.
- Check battery levels on locks, sensors, and doorbells, and replace anything below half rather than gambling on it lasting.
- Confirm push notifications actually arrive on your phone, including with the screen locked and on mobile data instead of home WiFi.
- Test remote access away from the house, such as from a coffee shop, so you know the apps work outside your own network.
- Write down your router admin details and any hub recovery codes and store them in your password manager, not on a note at home.
Step-by-Step Vacation Setup
- Set the thermostat to a setback, not off. In cold weather hold the house at a temperature safely above freezing, commonly around 12°C or 55°F, so pipes stay safe while you avoid heating empty rooms. In hot, humid climates keep cooling running at a higher setpoint, around 28°C or 82°F, so humidity never climbs high enough to grow mould. Schedule the normal temperature to resume a few hours before you land.
- Turn off the water at the main, or at least the appliances. Supply hoses to washing machines and dishwashers are the most common source of catastrophic leaks. If you cannot shut the main because of an irrigation system or ice maker, close the individual valves behind those appliances instead.
- Place leak sensors where water would appear first. Put one under the water heater, one behind the washing machine, one under the kitchen sink, and one at the lowest point of a basement. Confirm each triggers an alert by touching the contacts with a damp finger before you leave.
- Build a lighting schedule that looks lived-in. Avoid a single lamp snapping on at exactly 19:00 every night. Use randomized on and off times across two or three rooms, follow a plausible pattern from kitchen to living room to bedroom, and let everything go dark at a normal hour rather than burning all night.
- Unplug or de-energize the electronics you do not need. Games consoles, printers, desktop computers, and space heaters should be off at the socket. Controllable outlets let you cut power remotely and restore it before you return, which is both a safety measure and a small saving on standby draw.
- Set up entry alerts on doors and windows. Contact sensors on the front door, back door, and any accessible ground-floor window give you an instant notification. Pair them with the door lock so an unexpected opening while you are away escalates immediately rather than sitting in a log.
- Create a temporary access code for whoever is checking in. Give a neighbour, house-sitter, or pet carer their own code with a start and end date so it stops working the day you return. Never share your master code, and enable the log so you can see exactly when each visit happened.
- Point cameras at approaches, not at rooms you do not need to watch. Cover the front door, the driveway, and any side gate. Set motion zones tightly so passing traffic does not bury you in alerts, and switch on person detection if your system supports it.
- Verify cloud recording or local storage has capacity. A camera that overwrites in two days is useless for a fortnight trip. Extend the retention window, add storage, or reduce the number of recording triggers so the footage that matters survives until you get home.
- Arm the security system in away mode and test the escalation path. Trigger a test alarm, confirm the notification, and check who gets called if you do not respond. Tell your monitoring provider and your neighbour that you will be away and who is authorised to enter.
- Stop deliveries and mail, or redirect them. A full mailbox and stacked parcels advertise an empty house more clearly than any dark window. Where possible have parcels held at a locker or collection point instead.
- Take a final walkthrough with the app open. Room by room, confirm every device shows online, the thermostat is at the holiday setpoint, the lock is locked, and the alarm is armed. Then check the same screen once you are a few kilometres away.
Choosing the Devices That Do the Heavy Lifting
Four categories deliver almost all the value. A learning thermostat handles the setback and holiday scheduling automatically and reports if the heating fails to reach its target, which is your earliest warning of a boiler problem; our comparison of the best smart thermostats explains which models expose that kind of alerting. A connected deadbolt removes the hidden key under the mat and gives you dated access codes, and the best smart locks roundup covers battery life and offline behaviour, which matter far more when nobody is home to intervene.
Controllable outlets do the unglamorous work of lamp schedules and cutting power to appliances, and the models in our list of the best smart plugs include energy monitoring so you can see if a device draws power when it should not. For eyes on the property, choose cameras with sensible local or cloud retention rather than the cheapest option; the best smart home cameras guide compares storage options directly. If you want the whole set tied together with professional monitoring and a siren, our overview of the best home security systems covers packages that include sensors, a hub, and a response service in one subscription.
The Power and Internet Failure Problem
Every plan above assumes electricity and broadband keep working. Neither is guaranteed. Put your router, modem, and hub on a small uninterruptible power supply so a brief cut does not take the whole system offline for the rest of the trip. Many hubs also support a cellular backup or at least send an alert when they lose connectivity, which is worth enabling before you leave.
Decide in advance how each device behaves when it loses its connection. A good lock stays locked and keeps working from the keypad. A good thermostat keeps running its last schedule rather than reverting to a default. A camera with local storage keeps recording even when the cloud is unreachable. Devices that simply stop working offline should not be the only thing standing between you and an expensive problem.
Common Mistakes People Make Before Leaving
The first is announcing the trip publicly. Posting departure dates or airport photos in real time undoes every security measure you configured. Share the photos when you get back. The second is over-notifying: if every leaf blowing past a camera sends an alert, you will mute the app on day two and miss the one notification that mattered. Tune motion zones and sensitivity until you get a handful of alerts per day, not a hundred.
The third is leaving nobody with physical access. Cameras and sensors tell you something is wrong; they cannot mop a floor or close a window. Always have one trusted person nearby with a code and your phone number. The fourth is forgetting the mundane: bins, plants, a car left blocking a drive, and a heating system whose annual service falls due while you are away. Finally, do not install brand-new hardware the night before departure. Anything unfamiliar should run for at least a week so you learn its quirks while you can still fix them.
Frequently Asked Questions
Is it cheaper to turn the heating off completely?
Marginally, and it is rarely worth the risk. A frozen pipe or a mould outbreak costs far more than the modest energy used to hold a low setback temperature. In mild climates with no freeze risk, a much lower setpoint is fine, but off entirely is only sensible if the water is drained.
How many cameras do I actually need?
Two or three well-placed units beat six poorly aimed ones. Cover the main entry, the least visible approach, and any area where valuables are stored such as a garage or shed. Everything beyond that adds alerts without adding useful evidence.
Should I leave a radio or television on?
A randomized lighting schedule is more convincing and uses far less power. If you like the idea of sound, use a controllable outlet on a radio for a short window in the evening rather than leaving it running around the clock.
What should I do first when I get home?
Check the event log before you unpack. Look for leak alerts you missed, unexpected door openings, gaps in camera recording, and any device that went offline and never returned. Then restore your normal schedules, expire the visitor code, and reopen the water main slowly while watching for drips.
Final Thoughts
A vacation setup is not about owning the most devices. It is about making sure the four things that genuinely go wrong in an empty house get detected early and reported to someone who can act. Set the thermostat to protect the building, kill the water risk at the source, make the place look occupied, and give one trusted person a code that expires. Do that consistently before every trip in 2026 and you will come home to the same house you left, which is exactly the point.
