The UI shows an available firmware update (2.0.1 to 2.10) for my Zooz ZEN15 800LR. Clicking the Update button or manually uploading the firmware update results in the same error message: Error while calling firmwareUpdateOTA: Failed to start the update: Invalid hardware version! (ZW1503)

Successful firmware update

Additional context

Z-Wave device is a Zooz ZEN15 800LR, hardware version 2.0.
Stick is Zooz ZST39 LR on firmware v1.50, sdk v7.22.1

Already contacted Zooz support and confirmed I have the correct hardware version for the firmware update. They suggested I try filing a bug report here.

I'm getting the same issue with an Inovelli LZW36 switch. I definitely know this is the right firmware because 2 other switches of that model with identical datecodes, and purchased in the same order took it without issue.

I'm trying to revert back to 9.26.0. Oddly every Z-Wave device I've included since updating to 9.27+ is marked with a re-interview being necessary.

After re-interviewing the newer nodes, the newer, but firmware outdated LZW36 switch accepted the firmware update without issue and began updating.

Looks like there is something up with a change made in the 9.27.* update?

I'm getting a similar issue trying to update a HS-WX300
