Meross Outdoor Smart Plug vs Sonoff Zigbee Smart Plug S40 Lite comparison

Updated August 2026

Data from Amazon and official Meross and Sonoff sites.

2026 verdict

On the overall scorecard the Sonoff Zigbee Smart Plug S40 Lite is the better-value smart plug here, winning on a lower price and its Zigbee router role, neither of which the Meross Outdoor Smart Plug can match. That verdict carries an important caveat: the Meross Outdoor Smart Plug is the only one of the two with an IP44 weather-resistant housing and two independently controllable outlets, making it the obvious choice when the outlet lives outside. Both are 1800W, 15A Type B plugs and both work with Alexa, Google Home and SmartThings, so their control basics overlap. The designs simply point in opposite directions, one is a hub-dependent indoor Zigbee mesh device, the other a hub-free Wi-Fi outlet built for the yard. Take the Sonoff Zigbee Smart Plug S40 Lite for affordable indoor control that strengthens a Zigbee network; the Meross Outdoor Smart Plug earns its place wherever weatherproofing is the requirement.
