Add percentage-based position control for Sonoff MINI-ZBRBS shutter relay
Hello, I am using the Sonoff MINI-ZBRBS Zigbee shutter relay with the SonoffLAN integration. Currently, the device is recognized and I can control it to fully open or fully close the blinds. However, there is no option to set a specific position percentage (e.g., set the blinds to 50%). The only available controls are for complete opening and closing.

Hi Alexx,
I’m using the SONOFF MINI-ZBRBS (Zigbee shutter relay) integrated through SonoffLAN.
The device connects correctly via eWeLink and is recognized in Home Assistant, but it is not exposed as a cover entity — instead, it’s detected as a generic device or switch, which prevents percentage control and full shutter functionality.
After some testing, I found that the device has uiid: 7034 and behaves identically to other shutter-type devices.
By inspecting the custom_components/sonoff/core/devices.py file, I confirmed that uiid 7034 is not mapped as a shutter.
✅ Working solution
Adding the following line to the DEVICES dictionary in devices.py solved the issue:
After restarting Home Assistant, the device appears correctly as:
and supports full open/close/stop/position control.
💡 Suggestion
Please include this mapping in the official devices.py list so that uiid 7034 is recognized as a shutter device by default.
Optionally, this could be improved to detect the device automatically based on its model ("MINI-ZBRBS") for future-proofing.
Thanks for your great work maintaining SonoffLAN!
This change makes the MINI-ZBRBS fully functional as a cover entity.
It's great that you found the solution yourself. I assumed this converter might work, but I don't have the device to test it myself.
