I use it and like it. DNA and all. Yes it's expensive. I generally pay for a month, then let it expire for a few months while I catch up, then renew as needed.
It is the 900 pound gorilla of the hobby. If you want to get DNA matches, it's the first choice by far. And it has enabled me to learn an enormous amount about my family - and my wife's, and several friends who are interested.

An Insteon integration with a hub and a bit more than a dozen switches, water sensors, etc.
Maybe 4 or so z-wave devices connected via a USB dongle on the Pi.
The Alexa integration for the direct Wi-Fi bulbs. Maybe 6-ish. Also for wife-acceptance.
