The synchronous expectation trap is hard to get around especially in places that are new to remote working. Of course open communication about expected hours of availability can go a long way to alleviate this but everyone has to be open to compromise on that. The fact that your home is also your "work" should not lead to your supervisor/manager/lead/whatever assuming that you are available whenever they feel like it.
Yes it sucks if people call you at weekends or at night, but it also sucks if they want face-time in working hours, independent of the fact that I'm in office or not.
I mean I don't have a problem with 1-2h a week or a 1-2 day workshop every few months, but some people are just always behind your back :D
