How? Large Migration. Do it slowly, over time by running HA and Homeseer in parallel

HS4 user here, I’m just in the beginning (2-3 weeks of actual use; 1 month of reading before that) of prospecting HA for a complete switchover.

Not knowing where you are at in your migration, I will highlight some of my base observations so far.

  1. HA is extremely flexible in it’s Automation.

  2. HA is far more “Modern” in both it’s automation engine and UI.

  3. The path to success, even for very basic functions can be extremely resistive (filled with possible problems and pitfalls with time consuming configuration setups).

Examples:

  1. I cannot get simple TTS working with any of my Chromecast Device.
  2. I cannot easily mount a (that persists updates) windows network path to HA’s media folder (where all streaming begins inside of HA) (using VirtualBox on a Windows 10 machine)

As for migrating you’re Z-Wave devices… Oh man… I have not even begun to tackle that space. I think most are running parallel HS and HA system for their Z-Wave devices because of HA issues with Z-Wave.

This is a fantastic thread on the issue
