Sonoff App 1.13.1 - MINI-ZBRBS reports inverted cover position (0% = open, 100% = closed)

Questions & Help

Hi,

I believe there is an issue with the MINI-ZBRBS driver.

The shutter itself works correctly and calibration completes successfully. However, the reported position appears to be inverted.

Current behavior:

  • When the shutter is fully open, Homey reports 0%.
  • When the shutter is fully closed, Homey reports 100%.

Using the Homey Developer Tools:

  • Setting windowcoverings_set = 0 fully opens the shutter.
  • Setting windowcoverings_set = 1 fully closes the shutter.

Because of this, integrations such as HomeKit (via HomeKitty) report the wrong state. Apple Home shows the cover as Closed when it is physically Open, and Open when it is physically Closed.

The issue persists after removing the device, pairing it again, and recalibrating it.

Expected behavior:

  • 0% = fully closed
  • 100% = fully open

Could you please verify whether the position mapping for the MINI-ZBRBS driver is inverted?

Thank you.

I assume you are using the official SONOFF app for Homey (by StyraHem Sweden)? You can reach out to the developer via the contact details on the app’s app store page.
