Trouble with DD7002B Connector Bridge – AccessToken errors in Motionblinds integration

Third party integrations
1

Hi everyone,

I’m trying to integrate my DD7002B Connector Bridge (for roller blinds) into Home Assistant using the built-in Motionblinds integration.

  • I successfully discovered the bridge, and the blinds show up in HA.
  • I retrieved the API key by going into the Connector app → Profile → About → tapping 5 times. The key looks like this format: 27133932-4cea-4a which matches what the docs say.
  • However, whenever I try to control the blinds I get repeated errors like this in the HA logs:
    Received actionResult: ‘AccessToken error’, when sending message:
    {‘msgType’: ‘WriteDevice’, ‘mac’: ‘a4cf1288eab40002’, ‘deviceType’: ‘10000000’,
    ‘AccessToken’: ‘xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx’, ‘msgID’: ‘20250912121907702’,
    ‘data’: {‘operation’: 5}}

So the blinds are detected but won’t respond to commands.

What I’ve tried:

  • Resetting HA integration and re-adding the bridge.
  • Confirmed the hub IP is correct and accessible on my LAN.
  • Double-checked the app key multiple times (it’s always the same).

Questions:

  1. Has anyone else with the DD7002B seen “AccessToken error” with the Motionblinds integration?
  2. Is there a different way to extract the correct key for this bridge?
  3. Would resetting the bridge and re-pairing help, or is there another step I’m missing?

Any advice or success stories with this model would be much appreciated!

Thanks in advance.

Hi,
sadly I haven’t gotten a solution, but I’ve got the same issue.
I’ve got a Yooda Smart Home 2 gateway module which communicates with the Connector app.
Connection to the gateway seems to work but not the commands.

Bonsoir, j’ai également la Yooda Smart Home 2. J’arrive a communiquer avec Home assistant avec Motionblinds.
Mais parfois cela ne reponds pas toujours.
En general les volets s’ouvrent , mais ne se ferment pas.

I did an update yesterday night, of the Yooda Smart Home 2. From now, not working anymore:

Thank you!
