Made a bracket for mounting the sensor to 4020 Aluminium brackets. Might come useful for others!

The description of the wire colors does no longer match the product description:

Happy to report, that this description from the product page is currently valid. Note the color change for the Modbus Wires. I suggest adding a note, that in case the user recieves the "Sensor_startup_failure" notice in the App to swap the Modbus Wires A and B.

PIN # Color PIN name Description

1 RED VCC 5V～12V power input
2 Black GND Ground

3 Yellow B RS485 B
4 White A RS485 A

Thanks for the suggestion, we had considered popping up the action suggestion on the configuration page as well, but having a "Sensor_startup_failure" is not completely a wiring issue.
