Which version of Indigo (Lite or Pro) should I buy?
It really depends on your needs. If you are new to Home Automation and have only a few (20 or less) devices, you should try out Indigo Lite. If you want to control an unlimited number of devices, high-end devices (thermostats, sprinklers, multiple I/O devices), integrate with other applications (iTunes, etc.), or have complex automation requirements, you’ll probably want the full power of Indigo Pro. If you purchase Lite and later decide to upgrade to Pro, you can purchase a Pro upgrade code that will unlock the Pro features in your current installation — no new installation or reconfiguration necessary. The feature comparison chart will help you decide which version is for you.
