With a smart plug you can easily control on/off of the device you have chosen to connect to, eg control an element with plug and switch it on when the temperature in the house drops. Fibaro's smartplug is so small that it does not block the power socket next to it, which makes it possible to have two smartplugs next to each other.
Fibaro Wall Plug is grounded and has a built-in meter that shows the consumption of the device connected in it in real time. Around the outlet there is an LED ring that changes color after the load, it can be switched off if desired. The socket is controlled via the app to your smarthub (must have support for Z-wave), manually on the button on the socket or via the Tibber app (for heat control). Max load 2500 W.
