Updating and upgrading has been my entire experience with Home Automation. Never ONCE... have I ever even thought I was done with making my setup bigger and better.... no matter what I've told my wife.
For some time after the old X10 closed their doors.... my setup was in a depressing state of limbo. The depression lifted when Amazon entered the industry (bring with them billions of dollars and enormous innovation). But it's taken a few years for Amazon to create a app that effectively replaces the AHP... IMHO. Home Automation looks brighter than ever now... and more affordable too.
I still hope X10 finds a niche in the market.
