That is correct. MobiLinc HD was designed for landscape only mode on the iPad. Portrait mode is being considered as an upgrade to a future release.
The program shown is the interface to the ISY-99i INSTEON controller that comes with the ISY-99i product. Find out more at the mobilincstore's website.
At the end of the video I listed out all the INSTEON equipement used in the video and where you can purchase the equipment. For just the INSTEON equipment, it is less than $500.00. That doens't include the iOS device or networking equipment like a router and internet access.
There is an option that you can enable in MobiLinc that will ask for the ISY or PowerLinc password on startup before allowing the user to have access to your lights, irrigation, tstats, and garage door.
