Sonoff WiFi Smart Plug S60 vs Sonoff Zigbee Smart Plug S40 Lite comparison

Updated December 2025

Data from Amazon and official Sonoff site.

2026 verdict

In this all-Sonoff face-off the Sonoff WiFi Smart Plug S60 is the more capable smart plug, taking the win on a huge 4000W maximum load, built-in energy monitoring, overheat/overload protection and wider onboard connectivity. It pairs directly over 2.4GHz Wi-Fi with no hub, while the Sonoff Zigbee Smart Plug S40 Lite is Zigbee-only and needs a coordinator to run. Where the Sonoff Zigbee Smart Plug S40 Lite pulls ahead is a lower price, a slightly longer integration list (it adds Samsung SmartThings) and its Zigbee router role, which repeats mesh signal to other Zigbee devices. Both are 1-year-warranty Sonoff plugs, so brand and support are common ground. Pick the Sonoff WiFi Smart Plug S60 to safely power and track a washer, dryer or heater; the Sonoff Zigbee Smart Plug S40 Lite is the cheaper choice for extending an existing Zigbee mesh.
