If you turn your home into a smart home, you can enjoy convenient functions: the light switches on automatically at the specified time, the heating is turned down when the window is open or an alarm is triggered when the IP camera detects movement. The respective devices and their commands are configured and controlled via smartphone app. You can also control many smart home centers using voice assistants or smart displays. But even in a smart home, wall switches or buttons with which you can quickly call up a desired function are still useful. How do you explain what to look out for?
With a smart switch, you can switch the light on and off in the classic way at the touch of a button. They are connected directly to the existing neutral cable, replace the existing light switch and expand it with smart functions. Buttons do not require a power connection and only give the necessary switching impulse for activation. They are usually powered by a battery, which has follow-up costs. Smart switches and buttons that use energy harvesting can do without batteries. Pressing the switch generates the energy required for a radio pulse.
Connection to the base station
Which smart switch is suitable for you depends first of all on the wireless protocol of your smart home system. In addition to WLAN, Z-Wave, Zigbee and EnOcean, some manufacturers also use Bluetooth and DECT ULE for communication.
