Release 4.2 breaks Samsung 2878

[thomasja27]

Get this error with my 2878 samsung AC, on Release 4.2. Rolled back to Release 4.1. Then everything works fine.

I get the same on master, & can confirm that 4.1 works

There's only 1 commit between 4.1 & 4.2, which is 7d5278a9188ead7da472163d52af9d0488cd2da5

#52 is related

Not sure if #52 is related, i have the same issue with Samsung 2878, running latest HA 2023.1.7 with 4.1 and it's working fine, while at that issue people can't get it to work in latest HA versions. As OP, 4.2 breaks it for me and 4.1 works

This was fixed with version 5.1

Can confirm 5.1 works fine with Samsung 2878
