What's Changed
Integration
- Starting HA while the CCU boots no longer re-anchors hub and sysvar entities. With
only CUxD connected, the central reported the dummy serialCUxD_SN0815. That was taken
as a CCU serial change, which moved all hub keys and left sysvars re-created as disabled
_2entities. The serial change is now accepted only on a running central and never for a
dummy serial (aiohomematic#3462).
