Hey, this is fixed in an unapproved pull request. In the short term, you can just make the changes to your local copy of const.py in custom_components/wattbox and it will fix this problem.

It is also fixed in the develop branch, if you want to pull from there directly (which includes a few other fixes you may want).

Is it possible to have HACS pull from the develop branch instead of master?

[zacs]

@Automated-House yep, you can see here: https://hacs.xyz/docs/use/entities/update/

I believe you would just make that action call with develop as the version parameter. A bit manual, but should work fine.
