Good point on the per hydrozone SMS, which in an ideal world is the best way to go. That said, using 1-2 SMS's and making adjustments based on hydrozone requirements is no different in practice than any ET controller.
If you don't have the ability/money to use a SMS per hydrozone, then the best option IMO is a mixed approach, SMS with ET calculations. This does not necessarily mean you need to use a ET based controller in order to do this.
