Let apartment, light renovation
An already furnished dwelling, let as it stands. No building work, no rework of the panel, and a budget that has to pay for itself in a few months of bookings.

Backbone — network and Wi-Fi
EssentialThe only item in this scenario whose absence shows up in public reviews. Everything else is secondary beside it.
- Coverage and bandwidth
- One decent router and a well-placed access point beat three repeaters. Size for a group on holiday: several screens at once, not one occupant checking email.
- UniFi
- Guest network
- An isolated guest network, with a password simple enough to copy from a welcome book. The guest must reach neither the cameras, nor the thermostat, nor the owner's storage.
- UniFi

Security and access control
EssentialThe number one item in this scenario — the one that removes the key handover, therefore the journey, therefore the constraint that stops the property being let.
- Temporary keypad lock
- One code per stay, revoked automatically at checkout. Mechanical override mandatory and a reachable local contact: a flat battery at 11 pm must not leave someone outside.
- Aqara
- Detection
- A connected smoke detector, reporting to the owner. It is the one safety sensor that needs no arguing for on this kind of property.
- Aqara
- Video
- On outside entrances only, never indoors. The limit is stated explicitly to the guest in the listing: it is a mark of seriousness before it is a legal precaution.
Automation
OptionalAs little as possible, and that is advice rather than a budget reservation. A let property does not need scenes — it needs to work for someone who has learned nothing.
- Lighting
- Conventional switches. One or two connected lamps at most, as accents, and never on the primary lighting.
- Govee
- Air conditioning
- Connected thermostat with a setpoint ceiling and cut-off on window opening. The only item in this scenario with a demonstrable payback: it pays for itself in one season.
- Aqara
Energy
RecommendedElectrical sub-metering, in order to know. Without measurement, abnormal consumption only surfaces on the bill, months after the stay that caused it.
- Sub-metering
- A communicating meter on the dwelling's incomer. It turns a hunch into a fact, and lets you tell the next guest what is included.
- Aqara
Outdoors
Ruled outAn apartment has no gate, no pool and no irrigation. The block has no object here, and putting it in a quote would be selling thin air.
Audio and video
Ruled outA connected speaker in a transient dwelling is a personal account left behind, a history attached to someone who has gone, and an object that disappears. The television is enough.
Supervision and interfaces
OptionalA manufacturer's app is enough if the owner is not technical. Adding a supervision layer here means adding one more thing that can fail.
- Remote monitoring
- The app of the chosen brand — provided you choose one. Three apps for three devices means three forgotten passwords on the day something needs doing.
- Aqara
Ecosystem and assistants
RecommendedOne ecosystem, chosen before buying anything. That is what avoids ending up with four gateways for six devices.
- The choice
- Aqara covers lock, thermostat, detection and sensors on a single hub, and stays compatible with both Apple HomeKit and Google Home. On this segment, consistency beats the performance of each item taken separately.
- Aqara
- Apple HomeKit
- Google Home
What we advise against in this case
KNX, without ambiguity. Neither the budget nor the use justifies it on a dwelling of this kind, and we say so rather than stretch the quote.
And if your need comes down to a lock, a thermostat and Wi-Fi: you can do it yourself, and we are not the right people to call. We come in from the point where there are several units to manage, charges to apportion, or a building to take over.
