Homematic restore erzeugt Probleme mit Jalousien in Home Assistant

[Norm71]

Describe the issue you are experiencing

Da ich auf der RaspberryMatic fehlrehafte Blocks auf der Disk angezeigt bekam habe ich eine neue SD Karte bespielt und das Backup von letzem Monat restored.
Auf der Raspberrymatic funktioniert auch alles. Doch in HomeAssistant sind alle Jalousien nun mit Problemen zu betreiben.
Nach einem Neustart von HA geht erstmal alles. Dann nach ca.5-7 Schaltvorgängen bei den Jalousien kommt der Fehler: invalid literal for int() with base 10: ‘’

Describe the behavior you expected

Da RaspberryMatic ja restored wird sollte sich keine Änderung ergeben die zu Problemen bei HA führt.

Steps to reproduce the issue

1. Connect RM to HA
2. Backup RM
3. Flash Image to new SD Card
4. Restore the Backup
5. Restart HA
6. See if Covers (HmIP-FROLL) working

What is the version this bug report is based on?

3.69.7.20230626

Which base platform are you running?

rpi4 (RaspberryPi4)

Which HomeMatic/homematicIP radio module are you using?

RPI-RF-MOD
