Apparently back in September something on my setup on a HomeAssistant Blue failed. Trying to update things today has it giving me:
Failed setup, will retry: Invalid server version: Z-Wave JS Server version (1.38.0) is incompatible. Update the Z-Wave JS Server to a version that supports at least api schema 39
I've tried removing the add-on. reinstalling the add-on, restoring an old version (7.1, 6.2, and 6.1) and then letting the system update it to 7.2. Same result.
