Checksum calculation wrong on Victron 150/70 and other

[softwarecrash]

it looks like victron change something in the communication, so the new devices send at the end and itemdaly after the checksum byte a Async Hex (i think broadcast)

it looks:

PID     0xA071
V       22000
I       0
VPV     0
PPV     0
MPPT    0
CS      0
OR      0x00000001
ERR     0
LOAD    OFF
H19     1077
H20     0
H21     4
H22     117
H23     921
HSDS    16
Checksum        ▒:A2001002200000008
                                   :ADBED00750806
                                                 :AD5ED009708EA
                                                               :A8DED00970832

so the code doesnt regonize the right end after the checksum byte.

any idea how to fix that?
