I want to first state that I am an extremely happy HA user. I’ve been an advocate for the package and have gotten a number of friends and family to join the community. After 3+ years of frustration with the Z-wave implementation (and/or the Aeotec stick…hard to say which is the culprit) I finally invested a whopping $69 and bought a Vera Edge. My experience with Z-wave has been completely transformed. I’m using the Vera platform in HA (surprised no one has written an integration for it, but its super straightforward to add to configuration.yaml) and it all works flawlessly.
For those of you who have similar frustrations (and I know from this community and the discord chat that there are many of you), I strongly recommend giving this a shot. Vera UI is horrendous, but who cares…just use it to control your Z-wave devices and the only time you’ll ever need to deal with it is when you add another device.
