Third Reality 3RDP01072Z

Dual metering smart plug

A Zigbee 3.0 plug with two outlets that are switched and metered separately. Each outlet reports power, current, voltage, frequency, power factor and energy, within a shared 15 A and 1800 W limit at 120 V.

Specifications

The 3RDP01072Z, sold as the Smart Dual Plug ZP1, puts two outlets side by side on one Zigbee 3.0 plug. Each outlet has its own relay and its own meter, so two appliances on one wall outlet can be switched and measured independently. The body is compact enough that two ZP1s fit side by side in a standard two-socket wall outlet, giving four switched and metered outlets.12

Where it is used

  • Two plug-in appliances on one outlet, such as a coffee machine and a water boiler in a staff kitchen, each metered alongside the site's main meter.

    Multi-site energy monitoring
  • A small comms or AV position where one outlet must stay on in metering-only mode and the other can be switched off out of hours.

  • Comparing two similar appliances side by side, with power factor showing which one draws more current for the same work.

Interface

On the Zigbee network it joins as a router and extends the mesh for other devices.2

Endpoint 1 is the left or bottom outlet and endpoint 2 the right or top. Each endpoint carries its own standard Zigbee Electrical Measurement and Simple Metering clusters, so the two outlets report independently.4

A factory reset resets both outlets together and clears the accumulated energy of both. It cannot be undone, so record the energy totals in Edge before you reset the plug.1

The same Zigbee definition covers THIRDREALITY's Smart Wall Plug ZW1 (3RWP01073Z). It shares this interface, but take its ratings from its own manual.4

Setup

  1. Open pairing in Edge

    In Edge, open pairing on the Gateway's Zigbee network. The Gateway accepts new devices while pairing is open.

  2. Plug it in

    Insert the plug into an outlet near the Gateway. A new plug enters pairing mode by itself and its LED flashes red.1

  3. Or start pairing by hand

    With the plug powered, press and hold the button for more than 10 seconds until the red LED comes on, then release it. The LED flashes rapidly red, and the plug leaves pairing mode after 3 minutes if it has not joined.1

  4. Confirm the join

    The LED goes out when pairing completes. Check that Edge identifies the plug as Third Reality 3RDP01072Z and shows both outlets.1

  5. Check each outlet

    Switch outlet 1 and outlet 2 from Edge in turn to confirm which is which, then run a load of known rating on each and compare the power reading.

Common questions

Does it need a THIRDREALITY hub to work with Edge?
No. It is a Zigbee 3.0 plug, so it joins the Zigbee radio on an EpiSensor Gateway directly and Edge reads both outlets without a THIRDREALITY hub or app.1
Is the metering accurate enough for billing?
No. THIRDREALITY describes its power data as for reference only. Use it to see what individual appliances use and when, and use a revenue meter for billing.1
What happens to the energy totals after a factory reset?
A factory reset resets both outlets and clears the accumulated energy of both. It cannot be undone.1
