Checksum mismatch even though checksum is correct

Firmware update for the Eve Energy plug fails with the following error

Hm, I see, the reason is a spurious whitespace in the DCL entry. I'll report and trim before comparing the checksum.

I tested the new beta that was just released, but now when I try to update the Eve Energy this error shows up:

Gah right, fixed with: #834
