If you are actually commuting during that time, then yes it is legal, but you stated that you work from home so I'm not understanding how you could be commuting.
In employment law, actual commute time to and from your home to a work location are not payable time (that first trip). However, they can't require you to use an hour before and after as commute time when you aren't actually commuting.
You should contact the Wisconsin Department of Workforce Development to file a wage claim against the employer here. This is a legally protected complaint, meaning that you can not legally be retaliated against for making that claim.
