[3RMS16BZ / Third Reality, Inc] ???

What happened?

Updated to latest firmware but new features/settings are not visible.

What did you expect to happen?

I expected to see:

• Support for customizing
• Configurable "Cold-Down Period" (cooldown) setting
• LED Brightness settings

How to reproduce it (minimal and precise)

• Successfully OTA updated the firmware from v1.00.24 to v1.00.79 but saw no change in Z2M exposed settings.
• Interviewed the device - no change.
• Reconfigured the device - no change.
• Re-paired - no change.

Start with the 3RMS16BZ device definition and compare the reported firmware, clusters, and expected settings with the issue details. Check how the device is interviewed, reconfigured, and exposed to Zigbee2MQTT, then verify that customization, cooldown, and LED brightness settings appear after the firmware update and re-pairing.
