Getting "Response without listener" for eltako FSB61NP

since some time I have trouble to get RSSI and state of rollershutter of type FSB61.
It’s configured this way:

UID: enocean:rollershutter:iAct_r_OG_Dachfenster
label: Dachfenster OG
thingTypeUID: enocean:rollershutter
  enoceanId: xxxxxxxx
  senderIdOffset: 3
  pollingInterval: 300
  suppressRepeating: false
  sendingEEPId: A5_3F_7F_EltakoFSB
    - A5_3F_7F_EltakoFSB
    - F6_00_00
  broadcastMessages: false
bridgeUID: enocean:bridge:xxxxxxxxxx

Up, down and stop works well. But I don’t get a valid status or e.g. RSSI value.

In log I see following:
2021-01-05 14:29:28.479 [TRACE] [ernal.transceiver.EnOceanTransceiver] - >> Received header, data length 1 optional length 0 packet type 2

2021-01-05 14:29:28.481 [DEBUG] [ernal.transceiver.EnOceanTransceiver] - RESPONSE with code RET_OK payload 00 received

2021-01-05 14:29:28.483 [TRACE] [ernal.transceiver.EnOceanTransceiver] - Response without listener

Any idea?

Issue found:
Thing configuration option “Send Broadcast Messages” need to be enabled, because FSB61NP is using broadcast messages to report status.
