Where to start
Not with a "smart home" all at once. The best start is one thing that actually makes life easier:
- Lighting - smart bulbs (screw in and it works) or in-wall modules that make ordinary wall switches "smart";
- Smart sockets and plugs - schedules, energy consumption measurement, remote switching off;
- Sensors - motion (hallway light), window opening, flooding under the washing machine, smoke;
- Roller shutters - control from a phone and sunrise/sunset schedule.
Protocols without jargon
Smart devices must communicate somehow. In practice, you will encounter three approaches:
- Wi-Fi - the simplest, without an additional hub; with a larger number of devices, it can overload the home network;
- Zigbee / Thread - an energy-efficient "mesh" network, requires a hub, but works stably and locally;
- Matter - a common standard of the largest manufacturers: devices with the Matter logo work together regardless of brand and app.
To start: a few Wi-Fi devices will suffice. If you plan to expand - choose equipment with Matter or Zigbee, you will avoid being locked into one app.
What you can do yourself, and what with an electrician
You can install bulbs, plugs and battery-powered sensors yourself. It is worth calling an electrician when:
- you install in-wall modules under switches - in older installations, the neutral wire (N) is often missing in the back box, without which most modules will not work;
- you connect roller shutter drives or heating control;
- you want to have order in the distribution board - protections, relays, consumption measurement for the whole house.
Typical trap: module bought, wall chipped, and in the box only two wires. Checking the installation before buying costs less than corrections after.
Security at the end
Change default passwords, update devices and - if the router allows it - set up a separate network (e.g. guest network) for the smart home. Where possible, choose local control, which works even without the internet.
