core: HA light entity breaks with zwave-js 7.0.0+ (zwavejs2mqtt addon 0.9.0+)

The problem

Upon upgrading zwavejs2mqtt addon from 0.8.1 to 0.9.0, HA can no longer control the dimmer on my ZEN30 combo (relay/switch still works fine).

Looking at the entities for this device in the Z-Wave JS integration, it appears that the original light entity is now in “Unavailable” status, and a new light entity was created. This new entity does not work, e.g. state doesn’t change. The original and new light entities from core.entity_registry config file are shown below.

Z-Wave communication with the device is working fine. I can control the dimmer from the zwavejs2mqtt Control Panel, and there I can also see debug value changes when I manually operate the dimmer.

When I roll back to addon version 0.8.1, the original light entity works again.

Anything in the logs that might be useful for us?

I haven't noticed anything unusual in the HA logs or the zwavejs2mqtt addon log, but let me know if there's a specific thing I can go and check for more information.
