Checksum error in the log
## Alarm system
Magellan MG5050 with IP150

## Environment
Proxmox Virt Env, Debian 10, Docker Container

## Git branch
Master

## Describe the bug
Pai will run without issue on the surface but when I look in the log I can see 3 to 4 of the following message types per day. I am not sure what these mean so looking for an explanation. Pai does not disconnect and is still able to see state changes but I am just not sure what is being missed with the below ERROR.
