Can’t reverse TM616EGZT direction

Hi,

I’m just getting started with Home Assistant and so far I have most things running fine except for my most recent purchase.

I bought a few Roller Blind motors and instead of sending me the Wi-Fi version they sent the Zigbee one. I decided to keep them and ordered a zigbee controller to use with HomeAssistant. I bought the SONOFF ZIGBEE 3.0.

The Blinds motor is the TM616EGZT.

I have it all pairs and working fine even with Google assistant… EXCEPT….

I can’t for the life of me get the motor to swap it’s directions. One of my blinds , Up is down and Down is up.

The instructions say to “Short Press” the Pair key followed by the Up button until the led flashes… I’ve done this dozens of times multiple ways and it never works.

I don’t know anything about programming but through messing around in the devices options of Zigbee Home Automation I see Id codes like 0x8001 or 0x8002 for up and down or inverting directions but I don’t understand how to change any of that….

Sorry my ramblings are over complicated…. I would just like to reverse the controls directions.

Any ideas?
Thanks in advance
