I have several devices running BOINC and Science United; two Pis that are exactly the same (RPi1B+) with the exact same OS (Raspbian). One gets tasks and one does not; below is the result of 'get_state':

Any help getting this device running with Science United would be much appreciated; it is listed in the GUI as an attached project but does not successfully communicate and grab work.

Thank you.

Thank you.

That's your problem. Science United isn't a project, it's an Account Manager. Science United doesn't (itself) provide any work: it attaches you to other projects with work that needs doing.

Remove both SETI (which has gone into hibernation) and Science United from your list of projects, and re-attach to Science United as an Account Manager.

Hello Richard and thank you for responding; I removed Science United as a project (not even sure how I did that) and added it as a Project Manager. It is working now so thank you again!
