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.
