Asset Parameter

Asset Parameter Messages

Kelvin SmartApps™ can publish an Asset Parameter Message in order to (asynchronously) update a given Asset Parameter for a given Asset.

The Asset Parameter update will persist as soon as this message is synced with the Kelvin Cloud.

The AssetParameter Object supports the following attributes:

Attribute	Required	Description
resource	required	The KRNAssetParameter that this update is meant for.
value	required	Asset Parameter value (Boolean, Integer, Float or String).
comment	optional	Detailed description of the Asset Parameter update.

Examples

Basic Usage

This is how they can be created and published:

from datetime import timedelta, datetime

from kelvin.application import KelvinApp
from kelvin.message import AssetParameter
from kelvin.krn import KRNAssetParameter

(...)

# Create and Publish AssetParameter
await app.publish(
    AssetParameter(
        resource=KRNAssetParameter("my_asset", "my_parameter"),
        value=100,
        comment="reason why the parameter was updated"
    )
)
