Well, early days, but after doing a full backup I went with the update and this appears to be doing ok so far. My recorder is working, my history and energy dashboard still exist unlike any of the .7 releases.
This allowed me to upgrade Alarmo (which had a dependency above .6) and fixes a disarm bug.
Hoping HA for me is back fully functional!
This will 100% not end well. I think we’ve yet to see even hardened financial / data collection systems be hack-proof. A random gym is not going to safeguard that data and/or monitor it responsibly.
