Sonoff Orb-ZBDIM Zigbee Dimmer Wall Switch

Power metering shows the lighting circuit's consumption in real time, which the product page presents as "See Your Savings while Dimming".

SONOFF's pairing FAQ describes holding the button until the LED indicator starts blinking rapidly, so the unit carries an indicator for its network state.

Schedules, timers, preset brightness scenes and cross-platform scene linkage through the eWeLink app or the Zigbee gateway the switch is paired to.

The specification table rates the switch at 220-240V~ 50Hz, and the product description warns that it is a 220-240V only device, so it is not intended for 110-120V wiring.

Rated for incandescent and halogen bulbs up to 400W each, with leading-edge dimming reserved for legacy fixtures under 100W.

SONOFF's specification table reads "220-240V~ 50Hz 400W Max Resistive load", and the label on the back of the unit repeats the same figure.

The load compatibility panel on the product page warns that the dimmer is not suitable for fluorescent lamps, CFLs, LED strips or inductive loads such as motors and fans.

Dimmable LED drivers and dimmable electronic transformers for ELV fixtures are both listed as supported loads.

The product page caps dimmable electronic transformers at 200W and dimmable LED lighting at 200VA.

SONOFF's own FAQ answers it directly: the Orb-ZBDIM requires a neutral wire for proper installation and operation.

Zigbee over IEEE 802.15.4 on an EFR32MG21 MCU. It also acts as a Zigbee router and repeats the mesh for nearby devices, but it still needs a coordinator such as a SONOFF bridge, an iHost, an NSPanel Pro or a USB dongle to join.

The retail listing is titled "Compatible with Alexa & Google Assistant", and SONOFF's distributor documentation describes setting a brightness percentage by voice through Google Assistant.

SONOFF's description states the switch works across Home Assistant, Alexa and other smart home platforms through a Zigbee gateway.

The Orb-ZBDIM has no native HomeKit profile. Its product page carries a "Works with Apple Home Via Matter Bridge" section: a SONOFF ZBBridge-U or eWeLink CUBE republishes the switch into Apple Home over Matter.

SONOFF's distributor documentation lists Samsung SmartThings among the supported platforms, and a buyer reports the switch joining a SmartThings hub and appearing as a dimmable light.

The product page has an "Easily Integrates with Open-Source Platforms" section for Home Assistant through the SONOFF Dongle series, and owners report running the switch under both Zigbee2MQTT and ZHA.

The switch itself is Zigbee, not Matter. Its product page documents reaching Matter platforms through a SONOFF Matter bridge, the ZBBridge-U or eWeLink CUBE, and SONOFF sells the Orb-DIM as the native Matter version.

Overheat protection is one of the four safety badges on the product page, and the description says power is disconnected automatically when an abnormality is detected.

SONOFF lists overload, overcurrent and overheat protection for this model and no surge or overvoltage cut-off.

Overcurrent protection is listed among the switch's built-in safeguards.

Overload protection is listed among the switch's built-in safeguards, alongside overcurrent and overheat.
