@bobbyD I decided to test the firmware update on a hub with no z-wave devices paired - in fact I had the z-wave radio disabled on the hub and had to enable it before I could update to 7.17.1. It's been somewhere around 5 minutes now and the update is crawling... only at 34% done. Is this the right behavior?
New: my 1st hub (no devices) finished the firmware update after > 10 min. I decided to start the update on my 2nd hub, which hosts all my z-wave devices. After 6 min or so it failed with this message. What do I do now? @bcopeland
