Easy configuration, network cable is going to work reliably as described. Only the number of devices (control unit + Gataway + router + valve control = 3 + x) could be a "perfect solution" reduce by a router manufacturer (eg FritzBox + valve control = 1 + x, AVM is working ...) but you know that before buying, so no points deduction.
The iOS app is not iptimiert for the iPad, here there is only the portrait iPhone app with 2x magnification. But it is very clear and easy to use.
