Data from the official Fibaro and Sonoff sites.
2026 verdict
Hub-free Wi-Fi versus a Zigbee mesh node: the Fibaro Wall Plug (EU) is the stronger smart plug overall, winning on a higher owner rating, a hefty 2500W maximum load, built-in energy monitoring and overheat/overload protection, plus richer onboard connectivity. It runs directly over its own 2.4GHz Wi-Fi and Bluetooth with no hub required, whereas the Sonoff Zigbee Smart Plug S40 Lite is Zigbee-only and cannot do anything without a Zigbee coordinator. The Sonoff Zigbee Smart Plug S40 Lite claws back real ground on price, on a much longer integration list (Google Home, Alexa, SmartThings, Home Assistant and IFTTT versus Fibaro's Apple HomeKit and Alexa only), and on its ability to work as a Zigbee router. Pick the Fibaro Wall Plug (EU) for a self-contained, well-rated plug with power tracking; reach for the Sonoff Zigbee Smart Plug S40 Lite if you are extending a Zigbee network and want wide voice-assistant reach on a budget.
