First of all; SUPER DUPER THX TO HOMEYS FANTASTIC SUPPORT!!! It was only my own fault that I trusted Homey and important devices since 2019, all my heating, all my important things like hot water tank, was controlled by z-wave units. Many of these devices was not accessible without electrician and i prepared my family to move out until the problem was solved. This isn’t Athoms fault all though it might be a bad update. Anyway; we ended up with taking a full USB backup that was transferred to Athom, and after some tests, restore of the new backup file with USB, **AND** a new restore from cloud, everything worked fine. I was so desperate, almost afraid, -7 degrees outside, cold house, cold water. It’s only my own fault it was that way, but Homey as always worked with z-wave from my first H2019. It was always zigbee that could make some errors. I asked Dennis at support what to write here, so that Athom isn’t spammed with large files (my list shows about 25 users with the same problem - just contacting me directly), and he has not yet answered, som please hold on a bit if you still have the same problem. We kept on working with the problem until late night yesterday. Anyway, I’m sure that there will come a solution for everyone in a new update, but I’m so grateful for the urgent help! Thx Athom! --- _[View the full topic](https://community.homey.app/t/all-z-wave-devices-are-gone-after-latest-firmware-update-to-10-1-0-on-h23/94736)._
