LGTM

This seem like something that should be caught in the library and wrapped in a known lib exception?

[puddly]

Rewritten to use zigpy.exceptions.TransientConnectionError now that #85355 has been merged into dev.

Should this still be included in a hotfix release? (Currently, the PR has the 2022.12.9 milestone instead of 2023.1.x)

[puddly]

Thanks! I've updated the milestone.
