Sonoff Orb-ZBRBS Review: A Compact Zigbee Shutter Switch Home Assistant Owners Like, With Quirks
The Sonoff Orb-ZBRBS is a one-gang Zigbee 3.0 wall switch that drives an existing AC roller shutter motor, with percentage positioning and a physical up and down key that keeps working by hand. Owners with Home Assistant praise how small it is, how easily it pairs over ZHA or Zigbee2MQTT and how automatic the calibration is. The recurring complaints are practical: the first key press often does nothing after the shutter has sat at an end stop, some units drop off the Zigbee network every few weeks, the 1A motor limit rules out many motors, and the body does not fit every European flush box or switch frame. It suits small roller shutters in a Home Assistant home, not a no-hub setup or a heavy awning.
- Home Assistant and Zigbee2MQTT users
- Small roller shutters and blinds
- Tight flush boxes
- Percentage positioning and schedules
Pros
- Compact one-piece switch that fits tight flush boxes
- Quick pairing and local control with Home Assistant over ZHA or Zigbee2MQTT
- Automatic calibration and percentage positioning that can be started from Home Assistant
- Acts as a Zigbee router that strengthens the mesh
- Keeps a physical up and down key on the wall for manual use
- Alexa and Google Home through the eWeLink account, SmartThings through Matter
- Good value for the price
Cons
- Needs a Zigbee coordinator and a neutral wire
- First key press often does nothing after the shutter rests at an end stop
- Some units drop off the Zigbee network every few weeks and need a re-pair
- Limited to a 1A motor, which rules out many motors and large awnings
- Does not fit every European flush box or switch frame, and has no mounting claws
- Thin documentation and calibration needs a firm bottom end stop
- No energy monitoring, and Apple Home and Matter only through a SONOFF bridge
Who is the Sonoff Orb-ZBRBS for?
It is for someone with an existing 4-wire or 5-wire AC roller shutter motor who wants app, schedule and percentage control without replacing the motor, and who already has a Zigbee coordinator. Most owners run it with Home Assistant, though a few use a router with a built-in Zigbee radio. Because the key and the electronics are one unit, it fits flush boxes where a separate relay and a wall key would not, and several owners fitted one per window. It needs a neutral wire, and it is not meant for a large exterior awning or a heavy motor.
What do owners like about the Sonoff Orb-ZBRBS?
The recurring praise is the compact, solid build and the clean integration. Pairing with Home Assistant over ZHA or Zigbee2MQTT is quick, the covering shows up as a cover with position, and calibration can be started from Home Assistant, often fully automatically, without pressing the back button. Once calibrated, percentage positions, automations and scenes work well, and Alexa can see it through Home Assistant or the eWeLink account. Owners also like that the key and electronics sit together, that the unit repeats the Zigbee mesh, and that it costs less than most rivals.
What to know before you buy
The most common complaint is the key: after the shutter has sat fully open or closed for a few minutes, many owners say the first press does nothing and the second one works, and some units stop reacting to the key until power is cycled. Sonoff is said to know the issue, and owners work around it with a Home Assistant automation. Connection drops are the next worry: a number of owners with several units report one dropping off the network every few weeks and needing a breaker cycle and a re-pair, in both ZHA and Zigbee2MQTT. Fit matters too. The unit is made for a 1A motor, which owners translate to about 230 W, so a large motor or awning is a risk. It does not suit every European flush box, switch programme or two-gang frame, and there are no mounting claws. Calibration needs a firm end stop at the bottom. Documentation is thin, the wiring takes a little puzzling out, and results with Homematic or an Alexa hub as the only coordinator were poor. A couple of units arrived defective.
Is the Sonoff Orb-ZBRBS worth it?
For a small roller shutter in a Home Assistant home it is an affordable, neat way to get percentage control and automations, and a happy majority rate it well. Plan for the double-press bug, check the motor draw and your flush box before you buy, and keep the return window in mind in case a unit drops off the network. If you want a plug-and-play shutter switch without a coordinator, a heavy motor or a guaranteed fit in every European frame, look at another brand.
Frequently asked questions
Does the Sonoff Orb-ZBRBS need a hub?
Yes. It is a Zigbee 3.0 device with no Wi-Fi or Bluetooth, so it needs a Zigbee coordinator such as a SONOFF bridge, iHost, a ZBDongle-P/-E or Home Assistant running ZHA or Zigbee2MQTT. Owners who tried to connect it to Homematic IP or to an Alexa hub alone were disappointed.
Why do I have to press the key twice?
Many owners report that after the shutter has rested fully open or closed for a few minutes, the first key press is ignored and the second one moves it. Owners work around it with a Home Assistant automation, and some say the maker is working on a firmware fix.
What motors does it work with?
A 4-wire or 5-wire AC roller shutter motor drawing under 1A at 100-240V. Owners translate that to roughly 230 W, so a large roller or awning motor can exceed it. It cannot run two motors in parallel.
Does it need a neutral wire?
Yes. SONOFF states that a neutral wire is required for proper installation and operation.
Does it work with Home Assistant and Alexa?
Yes. Home Assistant is the best-supported route, over ZHA or Zigbee2MQTT or the eWeLink account, and Alexa and Google Home work through the eWeLink account. Owners who used an Alexa hub alone found percentage control erratic.
How do I calibrate it?
Home Assistant can start an automatic calibration of the travel limits, so you often do not need the back button. It needs a firm bottom end stop to learn the travel, and an owner whose shutter had none could not calibrate it.
