There are two decisions you need to make when choosing a model. You must ask yourself if you would like to add IR communication capabilities to the ISY. This would allow you have ISY respond to your audio / visual remote control. The IR sensor is on the unit. Consider if you will be locating the ISY-99i where it can "see" IR commands. If you do not desire IR control or you will be locating the ISY outside of IR reception, then do not choose the IR model. IR Insteon control can be added later by adding an Insteon IRLinc receiver at the desired IR reception location. You must also ask yourself how large of an installation you anticipate having. The pro model offers support for up to 1056 devices, scenes and programs while the standard model supports 256. Please note that requirements vary significantly. We recommend purchasing the PRO model if you plan on having over 30 Insteon devices installed. This allows you plenty of programming capability per device. If you will have less that 30 Insteon devices, then stick with the standard model. Our Orchestrated MobiLinc application can create upwards of 5 - 10 programs per device when used to its full capabilities.
The Climate module allows ISY to evaluate weather phenomena in your area and can be used to adjust irrigation systems or other automated systems that need to be aware of the ambient weather conditions. This module can be a great resource saver and also provides the ability to quickly see the local weather via your internet connected device such as an iPhone.
The ISY Portal w/Network module adds the optional ability to synchronize
your ISY in the cloud on the Universal-Devices server which greatly
simplifies remote access as well as makes possible integration with web
based applications such as the Amazon Echo's ISY skill for voice command
of your devices and IFTTT (If this then that) web based triggers your
favorite web based applications / Social Media applications plus much
more. The Network feature is now included as part of this module
allowing users to use their ISY as a web server to serve up your own
applications, pictures, and files. The module also inculdes Wake On Lan
(turn your computers on using ISY progrmas) and Network Resources which
enable you to call any network resource (TCP/UDP/HTTP/HTTPS).
