Well, the EMail notification thing is fixed when 3.2.0 can be used. But in 3.1.17 if you clear the "From" field the notifications should work fine.
Unfortunately, I've never been able to get the ISY-99 to work with my own email servers due to authentication issues. So I have to use the default checkbox which does not allow setting of the From field.
Does anyone know the default values so I can enter them manually?
