It's great to hear you selected a system. Overall, any system pre-planned prior to build will/should be better than any retrofit. This is the ideal method for a smart home integration, and essential owner satisfaction.
IMHO, I have had only 1 Savant system that i had the unfortunate pleasure of having to work on . Not overly complicated, but when there are issues, it's not a DIY fix. It's, 'Call the Savant dealer/installer for the fix."
Information is NOT readily available from Savant, and in this particular situation, the owner of the system was rather disappointed not being able to perform simple troubleshooting on their own.
The 'All-In-One- type of solution is great, but be fore-warned, make sure you have a contract line item for every single deliverable for the things that you are expecting the system to perform,( such as turn on every light, TV controls, Audio Video Receiver, thermostats, alarm integration, sump pump notification, camera integration, etc) and operate as expected prior to sign off and acceptance of the system. This will save any headaches in the end. In addition, go line by line on contract review when delivery says is complete is a very good thing to do. In addition, make sure any training that you are paying for is schedule within a set time frame, usually prior to sign off and final payment.
All of this will save you and the dealer/installer heartburn and your money when something does not work. And there will be something that does not work.
Not to say that your vendor of choice is out to 'get you', but, it makes it allot more simple when everybody understands what the deliverables are in writing.
Good luck and wish you the best. Hope it all turns out for you.
