Repeated 'Not a proper sync' messages

[ImmutablLimited]

Hi

I have installed this service and connected to my truma heater via a linbus > UART connection from my rpi3.

I am getting messages through which is great but they are consistently marked as 'not a proper sync' as per the below

Any thoughts?

in < 80 5c not a proper sync -wait for sync-
in < 84 21 not a proper sync -wait for sync-
