Model: P400M
An outdoor Matter-over-Wi-Fi plug with two separately controlled outlets and an IP65 rating. It supports Tapo schedules and Away Mode. Matter setup needs a controller for the chosen ecosystem.
Catalog-level details. Controllers, bridges, accounts, and available features depend on the connection route.

What to know about this device before choosing a connection.
A recommendation is not recorded yet. Compare the requirements below with your home and the capabilities you need.
Two independent outlets and IP65 protection are documented; keep unused sockets covered as instructed. Product scheduling and Away Mode do not establish their exposure through each Matter platform. This is a Wi-Fi client; the advertised signal coverage does not establish mesh repeating. TP-Link explicitly states that P400M does not support energy monitoring. This is an unversioned manufacturer model statement; a countdown timer remains unverified. US documentation agrees on a device maximum of 15 A and 1800 W for general-use/resistive loads. The US datasheet limits total connected equipment to 15 A across the device; two outlets do not provide 30 A or 3600 W. Motor limits conflict: the product table states 1/2 HP, while the US V1.0 datasheet states 1/6 HP and an 8 A incandescent limit. The applicable motor limit remains unverified; confirm the exact unit/hardware documentation before connecting a motor.
Check your ecosystem, then choose a connection method for its requirements and available controls.
A listed ecosystem is a starting point. Connection methods and exposed capabilities must be checked for the exact variant.
