Model: S4PL-00116US
A compact US smart plug with power and energy monitoring, device schedules and local Wi-Fi control. Zigbee mode can relay Zigbee traffic; Matter and Home Assistant use their own connection paths.

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.
Exact US model technical/API documentation rechecked October 10. Zigbee router, Wi-Fi extender and BLE gateway are separate functions. Matter is the default profile; five control-button presses select Zigbee and start inclusion for three minutes. BTHome components are unavailable in Zigbee mode. Local Wi-Fi/Home Assistant does not need Shelly cloud; exact HA meter entities and simultaneous-mode behavior remain unverified. Compact design, 20 device-firmware schedules and a 15 A AC output limit are documented. The 1800 W figure applies to resistive loads. Product scheduling does not establish identical options through Home Assistant, Matter or Zigbee. Existing mode-specific network behavior, meter-entity limits and firmware unknowns remain in the connection guides.
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.

Original manufacturer pageOriginal manufacturer files, including its safety instructions. Diagrams may show different AC and DC configurations; check the exact model and supply type.
Earlier observations checked 9/28/2026. Later observations state their own dates. Certification claims below are attributed to the manufacturer.
For model S4PL-00116US, the manufacturer lists 120 V AC, 60 Hz, maximum switching current of 15 A, and maximum output power of 1800 W for resistive loads only. The page lists resistive, capacitive and inductive load types but does not give those other types a separate output rating.
Manufacturer sourceFor model S4PL-00116US, Matter firmware is the documented default; five rapid button presses switch the device to Zigbee firmware. These are alternative firmware modes, not simultaneous Matter and Zigbee operation.
Manufacturer sourceThe US storefront labels the exact product/model UL-Certified. This records Shelly's storefront claim only; the consulted content does not specify a certificate number or UL standard.
Manufacturer sourceLocal web control is available through the device access point or on the same local network. For Matter setup, the manual requires a compatible hub connected to the Internet. Zigbee setup uses a Zigbee hub and an alternative firmware mode. In Zigbee mode, the access point is off by default; holding the control button for five seconds enables it.
