Start with a problem, not with shopping
The most common beginner’s mistake: buying a set of "smart" devices because they look nice and then not understanding what they are for. Better to answer three questions first.
- What annoys or worries you now? A forgotten iron, a hallway light you have to switch off by hand, the risk of a leak while you are away, a hot flat while you drive home from work.
- Is the flat yours or rented? In a rented flat you cannot change wiring or drill walls, but you can use plug-in sockets, bulbs and sensors.
- What phone do you have? iPhone, Android or both in the family. Which system will be more convenient depends on it.
If the problem is not clear, do not buy anything: a "smart" kettle will not make your life better until it is clear what problem it solves.
How it works, in plain words
A smart home has three parts: devices (bulbs, plugs, sensors, cameras), the "brain" (an app on the phone, sometimes plus a separate hub) and the home network (Wi-Fi). If one part is weak, everything else suffers.
A hub is a small device that manages sensors and bulbs and lets them work together. Some systems have no hub: devices then connect straight to Wi-Fi and are controlled from an app. For two or three devices a hub is not essential, but when there are ten, it makes the system faster and more reliable.
Remember: a device that only speaks Wi-Fi cannot talk to a Zigbee bulb without a special hub or bridge. It is exactly this incompatibility that disappoints many beginners and makes them think smart homes are "unreliable".
Choose a system for your phone
The system you control your home in is called an ecosystem. The main options:
- Apple Home suits a family that is all on iPhone. Simple and neat, but fewer devices are compatible with it. For the Home app to accept Matter accessories you first need to set up a home hub — a HomePod mini or an Apple TV plays that role.
- Google Home is for Android but also works on iPhone. According to reviews, it is the easiest starting point for most beginners: clear setup, voice control and a practical path to Matter.
- Amazon Alexa has the widest range of compatible devices, but the voice assistant and interface in Russian and Georgian are limited.
- Inexpensive systems such as Tuya and Smart Life are found in cheap plugs and bulbs. They work, but the quality of devices and apps can be uneven. More on their security below.
- Samsung SmartThings is convenient if you have a lot of Samsung equipment.
Do not try to make three systems work together at once. Choose one main system and buy devices with its badge.
Matter, Thread, Zigbee, Wi-Fi: what they mean when buying
Boxes carry lots of abbreviations. You only need to remember four.
- Matter is a common standard that lets devices from different makers work together. Matter devices can be controlled from several apps at once, for example Google Home, Apple Home and Alexa. Advice for 2026: where possible, choose Matter-certified devices so you are not tied to one app.
- Wi-Fi is in every home. It suits cameras, video doorbells and anything that sends video, but it is not the best choice for other devices.
- Thread and Zigbee are low-power networks for small sensors and bulbs. They need a hub. Thread devices need a "border router" such as an Apple TV 4K or HomePod mini.
A simple buying rule: look in the description for the word "Matter" and the name of your system (Apple Home, Google Home and so on). Leave devices without clear compatibility on the shelf.
Wi-Fi: the foundation that is often forgotten
A smart home is dozens of devices, and they all work through your home network. A weak router and dead zones turn it into a source of irritation.
- Check that the Wi-Fi signal reliably reaches every room where devices will be. If not, a range extender or mesh system helps.
- Many inexpensive devices connect only to the 2.4 GHz band. If your router combines 2.4 and 5 GHz under one name, you may need to temporarily turn off 5 GHz during setup.
- A router you got from your provider and have not restarted for years often becomes the weak point. It is worth updating and setting up properly.
- Think about what happens when the internet goes down. Devices that work locally keep working; cloud ones do not.
Stage 1. Smart plugs: the easiest start
A smart plug goes into an ordinary socket and lets you switch the connected appliance on and off from your phone, on a schedule or by voice. It is the safest and cheapest way to try a smart home.
Good for: a lamp, a humidifier, a fan, a charger, a coffee machine with a button that can stay in the "on" position.
What matters:
- read the maximum power on the box. A heater, water heater and air conditioner draw a lot, and a weak plug can overheat;
- do not connect appliances through such plugs that are dangerous to leave on unattended;
- choose plugs that match your system and standard.
Stage 2. Lighting
Smart lighting is the most visible improvement.
- Smart bulbs. Screw one in instead of an ordinary bulb and connect it to the app. You can change brightness and tone and switch it on a schedule. Downside: if someone turns it off with the ordinary wall switch, it can no longer be controlled.
- Smart switches and relays. They replace ordinary switches and control any lamp. But they require working with the wiring.
Honestly about electrics. Replacing switches and working with wiring must be done with the circuit breaker off, and only if you understand what you are doing. Many smart switches need a neutral wire, which not every old flat has. If in doubt, better call an electrician or technician. In a rented flat use bulbs and plugs and leave the wiring alone.
Stage 3. Sensors: leaks, smoke, doors
These devices are less spectacular, but they give the most important thing: a notification when something goes wrong while you are away.
- A leak sensor goes under the sink, the washing machine or by the water heater. When water appears it sends a message to your phone and sounds an alarm. In an apartment building with neighbours below, it is one of the most useful sensors.
- A smoke and carbon monoxide detector. Choose certified models; a smart detector should not replace an ordinary standalone one — add to it, do not give up the proven one.
- A door and window sensor tells you a door has opened.
- A motion sensor turns on the hallway light at night.
A good habit: check the batteries and test the sensors every few months.
Stage 4. Cameras and video doorbells: privacy first
Cameras give a sense of control but raise the most security questions.
- Put cameras only where needed: entrance, hallway, yard. Not in the bedroom or bathroom.
- Use two-factor account protection and a unique password for cameras.
- Do not use unbranded cameras without updates: many cheap models connect to unknown clouds and their firmware is never updated.
- If you rent the flat to guests, cameras inside cannot be hidden, and booking platform rules and the law usually require disclosing any cameras. Check your platform’s terms.
- Remember that a Wi-Fi camera needs a good connection.
Stage 5. Climate: air conditioning and heating
For a southern city this is one of the most practical topics. An air conditioner you can switch on half an hour before getting home, and switch off when you forgot, saves both electricity and nerves.
- If your air conditioner already has Wi-Fi, connect it through the manufacturer’s app.
- If not, there are universal IR controllers: they "learn" the commands of the ordinary remote and control the air conditioner through an app.
- Smart thermostats for radiators and underfloor heating do not suit everyone: check compatibility with your heating system.
Stage 6. Locks: only if you are sure
A smart lock is convenient: a code instead of keys, access for guests and relatives. But it is the most serious decision.
- The lock must work reliably without internet and with a flat battery, and there must be a backup way to open the door for that case.
- Installation must be done well: a weak lock is worse than an ordinary one.
- Do not put everything on one unprotected account: hacking the account means access to the door.
- Do not start with a lock. Gain experience with plugs, lights and sensors first.
Smart home security
A smart home is a computer network, so it needs the same protection as a phone.
- Unique passwords for every manufacturer account and for Wi-Fi. Two-factor authentication wherever possible.
- A guest network for smart devices. Many routers let you create a separate network for bulbs, plugs and cameras. Then hacking a cheap bulb does not open access to your computer and phone.
- Updates. Install them on devices and in apps. If the manufacturer has stopped updating a device, that is a reason to replace it.
- Do not buy devices "from nowhere". Brands with a history and support are better than nameless ones.
- Look at what data the app collects. Turn off what is unnecessary, such as microphone and contacts access, if not needed.
- Change the router’s default password and keep its firmware up to date.
A staged shopping plan
Do not buy everything at once. A sensible order:
- The router and Wi-Fi, if there are problems with them.
- The hub of your chosen system (if needed) and two or three smart plugs.
- Smart lighting in one or two rooms.
- Leak and motion sensors.
- A camera or video doorbell, if you need one.
- Climate and everything else, once you understand what you actually use.
Live with each stage for at least a couple of weeks: you will see what really saves time and what turned out to be a toy.
Prices of such devices change, so I do not name sums. Compare offers on the day you buy.
Common mistakes
- Buying devices from different "worlds" and then looking for a way to connect them.
- Saving on the router and then blaming the "stupid smart home".
- Using weak plugs for powerful appliances.
- Installing a smart switch without understanding the wiring.
- Buying nameless cameras and sensors.
- Never updating devices or changing passwords.
- Installing many devices and not a single useful automation.
- Starting with the hardest things: locks and cameras.
A short checklist
- decided what problem the smart home solves;
- chose one main system;
- devices support Matter and your system;
- Wi-Fi is stable in every room;
- started with plugs, lights and sensors, not a lock;
- a separate network is set up for smart devices;
- two-factor authentication is on for every account;
- powerful appliances are connected through plugs with spare capacity;
- cameras are only where needed.
When to call a technician
You can take the first steps yourself: plugs, bulbs, sensors. But when you need to choose a system, set up the router and a separate network for devices, connect a hub and bring everything into one app, I will help.
I provide home-visit IT help in Batumi: I come to your home, help choose a system for your phone, set up the router and Wi-Fi, connect and configure smart devices, protect the accounts and explain how to use it all. I can also do light electrical work; if the job is more complex, I will say so honestly.
