Is there a page that differentiates why this is better than some of the OSS options available? HomeAssistant and OpenHAB are the two main options I know of, and both support way more than just z-wave. The page mentions the product is open source, does that mean it's possible to run it without sending all of my data to your servers? I'm all for new competitors for home automation, but if I have to sign up for a trial or pay a subscription, I'm less likely to even bother trying it if there isn't a huge advantage to do so..
