Specifications

The WP-P09D is the dual USB-C version of Aqara's Wall Outlet H2 UK: a double socket that replaces a standard UK twin outlet in a double-gang back box. Each of the two outlets is switched by its own button and relay, and the USB-C ports can be switched too. Aqara rates it at 230 to 250 V AC, 50/60 Hz and 13 A maximum, with overload and overheat protection.12

Where it is used

  • Fridges, water boilers and coffee machines in UK office kitchenettes, metered at the socket they are plugged into.

    Refrigeration energy monitoring

  • Socket loads in meeting rooms, classrooms and hotel rooms across an estate, switched off out of hours from Edge.

    Multi-site energy monitoring

  • Permanent socket-level metering where plug-in monitors tend to be unplugged or moved.

Power endpoint 1 is the whole outlet, endpoint 2 is socket 1 plus the USB-C ports, and endpoint 3 is socket 2. The switches use their own numbering: socket 1, socket 2 and the USB-C ports.4

The overload threshold can be written but not read back from this model, so treat the value you set as the only record of it.4

The outlet has no voltage reading and no internal temperature sensor over Zigbee.4

Setup

  1. Have it wired

    With the circuit isolated, an electrician connects live to L, neutral to N and earth to the earth terminal, fits the 10 mm spacer if the back box is only 25 mm deep, and mounts the outlet.1

  2. Open pairing in Edge

    In Edge, open pairing on the Gateway's Zigbee network.

  3. Start Zigbee pairing

    Double-press either button, then within 3 seconds press and hold it for 5 seconds until the indicator flashes purple, Aqara's signal for Zigbee pairing. A quickly flashing blue indicator means Thread pairing instead.1

  4. Check each outlet

    Plug a load of known rating into socket 1, then socket 2, and compare it with the matching power reading: socket 1 appears in the socket 1 and USB-C reading, socket 2 in its own.4

  5. Set the protections

    Choose what the sockets do after a power cut, and lock the buttons where occupants should not switch loads off.3

Common questions

Does the WP-P09D need an Aqara hub to work with Edge?
No. In Zigbee mode it pairs with the Zigbee radio on an EpiSensor Gateway, and Edge reads and switches it locally. It ships in Thread mode, so start Zigbee pairing with the purple indicator sequence.1
Can it meter each socket separately?
Yes, in Zigbee mode. It reports the whole outlet, socket 1 with the USB-C ports, and socket 2 as three power readings. Energy is reported for the whole outlet.24
Does it report voltage?
No. Over Zigbee it reports power, energy and current, but not voltage.4
How do I factory reset it?
Press either button 10 times in a row. That restores factory settings and opens pairing again.1
