SIA Integration

Hello everyone,
I wanted to put the SIA integration into operation today, but it doesn’t work correctly.

I use a BOSCH AMAX 2100 for which an external SIA DC09 receiver is set up, which also works. Similarly, a second receiver was set up:

AMAX

However, the second receiver (the SIA integration) only creates 4 entities, three of which are marked as ‘unknown’. only binary_sensor.9102_000002_connectivity receives and updates the status regularly.

Anyone an idea?

To complete this, here are the SIA codes that the Bosch AMAX 2100 uses:
