Integration not able to enter admin mode, setup only with manual admin mode, no state change outside manual admin mode

[dari0-ct]

Hello all,

experimenting with my Indexa 8000 (a JA 80) and this integration, I receive the following errors.

Querying components / Setup of the Integration only possible, if I enter admin mode via the keypad manually.
After the setup of the integration, integration quits admin mode.
The integration does not recognize sensor state changes.
