SONOFF ZBMINIR2 is a tiny Zigbee smart switch that looks very similar to the SONOFF Zigbee Extreme (ZBMINIL2) but requires a neutral wire and can act as a Zigbee router with up to 64 sub-devices. It also supports new features such as “Turbo mode” for extended range and “detach relay” mode where the states of external switches and relay are separated, so operating the external switch button won’t affect the relay state.
The tiny wireless switch can fit into the smallest EU-type/86-type/120-type mounting boxes and works with gateways supporting the Zigbee 3.0 protocol such as ZBBridge Pro, NSPanel Pro, and other compatible Zigbee 3.0 hubs. It also supports external switches (momentary, door, SPDT, and rocker), voice control through Amazon Alexa and Google Home, and like other SONOFF devices is designed to be controlled through the eWelink mobile app by default.
SONOFF ZBMINIR2 specifications:
- MCU – Unspecified – Potentially the same Silicon Labs EFR32MG22 Arm Cortex-M33 @ 76.8 MHz Zigbee microcontroller with up to 512 kB flash, up to 32 kB RAM as found in the ZBMINIL2
- Connectivity – Zigbee 3.0
- Input – 100-240V ~ 50/60Hz 10A Max
- Output – 100-240V ~ 50/60Hz 10A Max (2400 Watts)
- External switch – S1 and S2 input terminals
- Dimensions – 39.5 x 33 x 16.8mm
- Weight – 26.7 grams
- Casing material – PC V0
The ZBMINIR2 is quite smaller than the original ZBMINI and offers some extra features. The ZBMINIL2 is better suited for installations without a neutral wire, but otherwise, the ZBMINIR2 provides more options and features. You’ll find a comparison between the three models in the table below. Paisit reviewed the ZBMINIL2 with eWelink and Home Assistant, so you can check out that post to better understand how the switch integrates with MQTT-compatible frameworks. A review of the SONOFF ZBMINIR2 is also coming soon.
While the ZBMINIR2 should be compatible with any Zigbee 3.0 hubs getting a SONOFF Zigbee hub like the iHost provides better compatibility. Zigbee2MQTT is also perfectly compatible with the new Zigbee device from SONOFF meaning it should integrate with Home Assistant just fine like its predecessor.
ITEAD sells the SONOFF ZBMINIR2 (aka “SONOFF ZBMini Extreme (Neutral Wire Required)”) for $12.90 on its online store. As usual, you can get a 10% discount when using the CNXSOFTSONOFF coupon code.

The original mini has terrible reception. No mention of whether it’s fixed in this one.
If you look at their website it actually addresses this issue:
You got your wiring diagrams wrong. S1-S2 are terminals for connecting a simple on-off which flips the output status. NEVER connect a power line to either one of these terminals
