I no longer have a Jawbone UP with a button (used to have an UP24 but now have an UP2); does it still give you a notification on the phone if you change modes? If so, 2 and 3 can be done straight in Tasker without using SharpTools.
I know the newer wrist units no longer have buttons so I can’t change it to sleep mode just by holding a button.
If the notifications still exist, you might be able to get the others done as well leveraging Tasker to do the legwork and have it launch SharpTools widgets instead of containing everything within SharpTools (but I’m not 100% sure on this).
