Today marks my 1-week anniversary as a new ISY 994i owner which I purchased to replace my soon-to-be-bricked-by-Nest Revolv hub. I enjoyed the Revolv's ease of setup and use to control our modest Insteon-centric HA system. When I purchased it, the Revolv hub promised wide ranging support of numerous standards and included software upgradeable radios to enable future expansion. I was impressed by it's overall reliability, integration with IFTTT, and geofencing that just worked. The Revolv hub and iOS app did not offer more advanced features and programming, but it met most of my needs.
Most of you reading this already know the Revolv story and recent announcements, so I'll leave it at that. In weighing my options to replace my Revolv, my minimum requirements included features that would meet or exceed the functionality of my Revolv:
Comprehensive Insteon support
Mac OS X & iOS support (HomeKit not required due to current HomeKit issues)
Geofencing
IFTTT support
Push notifications
Optional expansion to support other standards (Z-Wave, Zigbee)
Simple setup & ease of use but capable of more advanced features & programmability
One of my other main requirements was that the manufacturer and/or device was established with a large user base due to my experience as a Revolv owner.
Based on my requirements and after a lot of research, the ISY 994i appeared to be the best fit. Upon receiving my ISY 994i/Insteon 2413S bundle I was able to quickly and easily get up and running. There was a bit of a learning curve, but the online documentation on the Wiki and information contained in these forums, as well as UDI's incredibly quick, responsive, and helpful online support (thanks Michel !) got me up to speed and helped me resolve a couple of minor issues which were self-inflicted (purchased Portal Module + Mobilinc module).
Using the ISY has been an epiphany and breath of fresh air. I was able to do a remote firmware update without issues, and I was able to quickly equal then exceed all of the previous functionality of my Revolv including rock solid geofencing (Mobilinc Pro + IFTTT on my iPhone, Mobilinc Pro + Locative on the wife's iPhone) and push notifications using Pushover and integration of my LaMetric.
I can't express how satisfied I am with my ISY and UDI and only regret that I didn't purchase one sooner The constant updates, improvements, support, and expansion including the Portal give me great confidence that I'll get a lot out of my investment for *many* years to come.
