Gear Fit2 Pro Permissions

Search This thread
I have a Galaxy S9+ and a Gear Fit2 Pro. Since I generally wear the Fit2 I would like to use Smart Lock with the Fit2 as a trusted device to prevent screen locking. But the only way I've been able to get that to work is to allow the Fit2 permissions for Calendar, Contacts, Location, Phone, SMS and Storage. Are all these permissions in fact required?

In addition to privacy concerns with these permissions, I don't want my wrist buzzing every time I get a phone call or text. And BTW I don't use Samsung's SMS messaging app, which they also seem to require. I use my Fit2 only to tell the time, and display heartrate, steps, calories, etc ..... I don't use it for communications, notifications, etc
