How to choose a smart plug, switch or remote
Communication standard. Wi-Fi devices need no separate hub, but each one connects directly to your router. Zigbee and Z-Wave devices work through a hub and pass signals between each other, which keeps a network steadier in a larger home. KNX, Homematic IP and wireless EnOcean systems are aimed at fixed installations that an electrician usually plans.
Installation method. A smart plug goes into an existing socket and works within minutes. A relay module is hidden behind the switch in the wall box, so you keep the ordinary switch and gain app control, but many models need a neutral wire and enough space in the box. DIN rail modules are fitted in the consumer unit, while battery-powered remotes and buttons can be stuck or hung up with no wiring at all.
Load and appliance type. Check the maximum rated current and the load type. A heater or water heater needs a model rated for high current, LED bulbs need a dimmer that supports LED loads, and blind or awning motors need controllers designed for them. Plugs with energy monitoring show how much electricity a connected appliance uses.
Control and compatibility. See whether the device works on your local network without cloud services, and whether it connects to Apple Home, Google Home or Amazon Alexa. A physical remote or button helps when your phone is not at hand or when guests are staying.

Frequently asked questions
What is the difference between a smart plug and a relay module?
A smart plug goes into an existing socket and controls whatever is plugged into it, while a relay module is installed in a wall box and controls the light or other load wired to it. The plug is simpler and suits rented homes. The relay module stays out of sight and lets you keep using the normal switch.
Do smart switches need a neutral wire?
Many smart switches and relay modules do need a neutral wire, because their electronics must be powered all the time. Some models can work without one, but they often come with extra requirements for the connected load. Check the manufacturer's specification and the wiring in your wall box before buying.
Does a smart plug work without internet?
It depends on the model and the system. Zigbee or Z-Wave devices with a local hub, and some Wi-Fi devices on a local network, can keep working without internet, but remote control through an app cannot. Schedules are usually stored on the device or the hub.
Should I choose Wi-Fi, Zigbee or KNX?
For a small flat, Wi-Fi or Zigbee is enough, as both are affordable and easy to start with. Zigbee is worth considering if you plan many devices. KNX suits new builds and major renovations, where an electrician designs and commissions the system.
