Ledvance Smart and wifi plug

The graphics are perhaps not so appealing and set-up is only possible via 2.4 GHz WLAN. But for the small price, the Ledvance plug at least provides remote control functions and a rough consumption overview.

If you only want to know the approximate power consumption of certain devices and record it via an app, the Ledvance plug is the cheapest option. But it stops at 2300 watts, and the Tuya-based app doesn't knock anyone's socks off.
