What is the difference between parameters and attributes?

Feature	Parameters	Attributes
Purpose	Control and monitor device state	Static metadata
Mutability	Read and/or write	Read-only
Examples	Power, Brightness, Temperature	Serial number, Firmware version
Synced via MQTT	Yes, updated dynamically	No, reported once at boot
Has UI type / bounds	Yes	No

Parameters are the live, controllable state (power on/off, brightness, sensor readings). They sync between device and cloud over MQTT and can be changed remotely.

Attributes are fixed metadata (e.g., serial number, firmware version) reported once as part of the node configuration. They describe the device or node and do not change during operation.
