2026 verdict
Setup ecosystem is really what decides this smart plug matchup: the TP-Link Tapo P125M pulls ahead on price, carries a longer warranty, and offers broader wireless connectivity by pairing 2.4 GHz Wi-Fi with Bluetooth for onboarding, while the Sonoff Zigbee Smart Plug S40 Lite has no Wi-Fi or Bluetooth radio at all and depends on a separate Zigbee hub to work. That dependency is also the Sonoff plug's real advantage: it doubles as a Zigbee router, repeating signal to other Zigbee devices on the mesh, a job the Wi-Fi-only Tapo P125M cannot do. Both plugs switch up to 15A, include a physical on/off button for manual control at the outlet, and skip energy monitoring entirely. Shoppers already running a Zigbee network through Home Assistant, Zigbee2MQTT, or a SONOFF hub get real mesh value from the Sonoff Zigbee Smart Plug S40 Lite, while anyone who wants a plug that talks to Apple Home, Google Home, Alexa, or SmartThings over Matter without adding a Zigbee coordinator will find the TP-Link Tapo P125M the more complete and lower-maintenance option.

Frequently Asked Questions
Which is better overall: Sonoff Zigbee Smart Plug S40 Lite or TP-Link Tapo P125M?
The TP-Link Tapo P125M wins overall. It costs less, carries a longer warranty, and offers broader wireless connectivity with both Wi-Fi and Bluetooth. The Sonoff Zigbee Smart Plug S40 Lite answers back with Zigbee router functionality that the Tapo P125M does not have.
What is the biggest difference between the Sonoff Zigbee Smart Plug S40 Lite and the TP-Link Tapo P125M?
How they connect. The Sonoff Zigbee Smart Plug S40 Lite has no Wi-Fi or Bluetooth radio and needs a separate Zigbee hub to work at all. The TP-Link Tapo P125M connects directly over 2.4 GHz Wi-Fi, uses Bluetooth only for onboarding, and is Matter-certified, so it can join Apple Home, Google Home, Alexa, or SmartThings through a Matter controller already in the house.
Does the Sonoff Zigbee Smart Plug S40 Lite extend a Zigbee network?
Yes. It doubles as a Zigbee router, repeating signal to help other Zigbee devices farther from the hub stay connected, which the TP-Link Tapo P125M, a Wi-Fi and Matter device with no Zigbee radio, cannot do.
Do either of these plugs monitor energy usage?
No. Neither the Sonoff Zigbee Smart Plug S40 Lite nor the TP-Link Tapo P125M tracks power consumption; both are on/off plugs with schedules and timers.
Who should buy the TP-Link Tapo P125M?
Buyers who want an easy, Matter-certified plug that reaches Apple Home, Google Home, Alexa, or SmartThings without adding a Zigbee coordinator, plus a longer warranty, should choose the TP-Link Tapo P125M.
Who should buy the Sonoff Zigbee Smart Plug S40 Lite?
Buyers who already run a Zigbee mesh through Home Assistant, Zigbee2MQTT, or a SONOFF hub, and want the plug itself to help extend coverage, should choose the Sonoff Zigbee Smart Plug S40 Lite.
