You can attend and listen in the Daily Scrum but not speak
From the Scrum Guide - The Scrum Master enforces the rule that only Development Team members participate in the Daily Scrum.
From Mike Cohn's blog on the Daily Scrum Meeting - ...many teams enforce a rule in which only those who are committed are allowed to talk during the daily scrum meeting.
All team members are required to attend scrum meetings. Since both the ScrumMaster and product owner are committed team members, they are expected to attend and participate. Anyone else (for example, a departmental VP, a salesperson or a developer from another project) is allowed to attend, but is there only to listen. This makes scrum meetings an excellent way for a Scrum team to disseminate information -- if you're interested in hearing where things are at, attend that day's meeting.
The purpose of the Daily Scrum meeting is for the team to share with their team mates progress of work and planning for that day. And it is tightly time boxed. So, the entire focus should be on the Sprint backlog and on the people who are doing the work.
One departmental supervisor (who manages 4 Scrum teams and other staff) I know holds a fortnightly all hands to share plans, admin matters and so on. You might want to consider something along those lines.
