Sonoff MINI ONE PM Zigbee Smart Switch

Bi-directional metering, so it reads balcony solar generation as well as consumption, with up to a year of energy history and electricity bill tracking with time-of-use rates

The power-on state is configurable, and a delayed power-on timer staggers the load after an outage

Detach relay mode separates the wired wall switch from the relay output so smart bulbs downstream stay powered

The terminal table lists both outputs as live wire output terminals, so the contact is not potential-free

The two L Out terminals switch mains live to the load and are internally connected for wiring convenience only

Indoor concealed installation in an 86-type, EU-type or 120-type wall box, 60 mm depth or deeper

A single press toggles the load; five seconds enters pairing and ten seconds is a factory reset

Schedules, countdowns, inching, group control and smart scenes in eWeLink, plus run-completion and maintenance-reminder alerts driven by the power readings, and Zigbee Binding for direct device-to-device control

SONOFF lists its Zigbee role as Router: 180 m to the gateway by default and 250 m with Turbo mode enabled

Over-the-air updates through eWeLink and Zigbee2MQTT

Rated 16A 110-240V~ 50/60Hz, single-phase only

The specification table states 16A 110-240V~ 50/60Hz and the manual warns the device is for single-phase use only

SONOFF rates the relay at 16A max resistive load

Mains AC only: the manual restricts it to a single-phase 110-240V~ supply

SONOFF's own FAQ answers that the MINI-ZB1GSP requires a neutral wire, and the terminal block reads N, L, L, L Out, L Out and S1

SONOFF's own comparison lists the connectivity as Zigbee 3.0/BLE: Bluetooth drives Proximity Mode, which lets the phone control the switch directly when the Zigbee gateway is offline

Zigbee 3.0 over IEEE 802.15.4, EFR32MG21 chip, 2405-2480 MHz per the FCC grant

SONOFF lists Google Home voice control for this model after the switch is added to eWeLink through a SONOFF Zigbee gateway and the account is linked, or through a SONOFF Matter bridge

SONOFF's compatible hub table lists on/off and smart scene through an Echo Plus 2nd, Echo 4th or Echo Show 2nd with a built-in Zigbee hub, and Alexa also works through eWeLink account linking

SONOFF's own comparison marks Apple Home as available only via a Matter bridge (ZBBridge-U, iHost or eWeLink CUBE with a SONOFF Zigbee dongle). Apple Home has no Zigbee radio of its own.

SONOFF's compatible hub table lists SmartThings through the Aeotec Smart Home Hub (V3), which pairs it as a standard Zigbee device; a SmartThings driver has to be imported to read the energy data

Zigbee2MQTT supports this exact model from version 2.11.0 and exposes state, power, current, voltage, energy totals, turbo mode, detach relay mode and overheat reporting. ZHA works through the setup script SONOFF publishes while its native support is pending review.

The switch itself is Zigbee, not Matter: SONOFF republishes it into Matter through its own bridges (ZBBridge-U, iHost, eWeLink CUBE with a SONOFF Zigbee dongle).

SONOFF describes dual overload and overheat protection that cuts power when the temperature passes the safety threshold, and Zigbee2MQTT exposes the resulting device_overheated attribute

Voltage limits are configurable in the app and the relay cuts the load when overvoltage or undervoltage protection triggers

Current limits are configurable in the app and the relay cuts the load when overcurrent protection triggers

Power limits are configurable in the app, and Zigbee2MQTT exposes overload_protection and power_protector for this model
