Z-Wave secure inclusion and robustness in HA

I consider to switch to HA, mainly I use z-wave components.
has someone experience with the secure inclusion of z-wave components (are all/most of the devices supported?) in HA and how reliable the network is?
At the moment I use openHAB, I would be glad if someone would share his experiences with this two topics.

  1. Any secure device is supported, whether the device supports it depends on the device
  2. The reliability of the Z-Wave mesh has nothing to do with whether you’re using HA, or OpenHAB. It’s down to the devices, and the physical configuration.
