Shelly S4PL-00116US

Compatibility

Compatible with EpiSensor Edge over Zigbee.

Pair it with the Zigbee radio on an EpiSensor Gateway. Edge reads it locally on the Gateway.

Edge reads 10 values from it, listed under Interface.

Specifications

The Plug US Gen4 is a compact plug-in switch for 120 V, 60 Hz outlets with NEMA 5-15 sockets. Shelly rates it at 15 A and 1800 W for resistive loads, with overheating, overvoltage, overcurrent and overpower protection, and it draws less than 1.5 W itself.¹

Power

Mains. Powered from the outlet it plugs into at 120 V~, 60 Hz, drawing less than 1.5 W itself.¹

Where it is used

• Single plug-in loads that run around the clock, such as vending machines, water coolers and under-counter fridges, where the energy between two dates shows what they cost.

  Refrigeration energy monitoring

• Office and retail equipment switched off out of hours from Edge, across several North American sites.

  Multi-site energy monitoring

• A Zigbee router in a spot where battery sensors need a nearby hop back to the Gateway.

Interface

On the Zigbee network it joins as a router and extends the mesh for other devices.³

Readings and settings, with units and ranges where Shelly publishes them. R readable, R·W readable and writable, W writable only.^1, 4

Power, voltage and current come from the Electrical Measurement cluster (0x0B04) and energy from the Metering cluster (0x0702), both on endpoint 1.³

The light sensor reports through Shelly's own Light Level cluster (0xFC21) on endpoint 1, not through the standard illuminance cluster, and it is not among the readings in the table.^3, 4

The plug's Zigbee definition has no setting for its behaviour after a power cut, so plan for the output state it comes back in rather than configuring it from Edge.⁵

Setup

1. Update the firmware first

   While the plug still runs its Matter firmware, update it in the Shelly app. Firmware cannot yet be updated over Zigbee.⁴

2. Switch it to Zigbee

   Press the button five times in quick succession. The plug switches from its default Matter firmware to Zigbee.¹

3. Open pairing in Edge

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

4. Start Zigbee pairing

   Press the button three times in quick succession. The LED flashes purple slowly while the plug looks for a network.¹

5. Check one reading

   Plug in a load of known rating, such as a kettle or heater, switch it on from Edge and compare the power reading with the load's rating.

Common questions

Does the Plug US Gen4 need a Shelly hub to work over Zigbee?

No. Once it runs its Zigbee firmware it joins the Zigbee network on an EpiSensor Gateway directly, and Edge reads and switches it locally without the Shelly cloud.^1, 3

What load can it switch?

Shelly rates it at 15 A and 1800 W for resistive loads on a 120 V, 60 Hz supply. Its documentation lists resistive, capacitive and inductive loads such as heaters, electronics, fans and refrigerators.^1, 2

Is it a router or an end device on the Zigbee network?

A router. It is mains powered and Shelly lists it as a Zigbee router, so it relays traffic for battery devices nearby.³

How do I put it back into Zigbee pairing mode?

Press the button three times quickly. The LED flashes purple slowly while pairing is open.¹

How do I factory reset it?

Within 60 seconds of plugging it in, press and hold the button for 10 seconds.¹
