State

The state extension works with the MudPi state manager to offer state based triggers. The state trigger is the reccomended way to respond to new state from components.

This extension does not take an extension level config and is focused on interfaces.

Trigger Interface

Provides a trigger that listens for a StateUpdated event on the state topic.

Option	Type	Required	Description
key	[String]	Yes	Unique slug id for the component
source	[String]	Yes	Component `key` to check for new state.
nested_source	[String]	No	If the data is an object this is the key from that object to fetch.
frequency	[String]	No	Number of times to trigger actions once trigger is active. Options: `once`, `many`. Default: `once`
thresholds	[Array]	No	Array of threshold configuration objects to evaluate the reading data to.
name	[String]	No	Friendly display name of component. Useful for UI.
actions	[List]	No	List of registered actions to fire.

Config Examples

Here is a config of a complete trigger.

"trigger": [{
    "key": "temperature_trigger",
    "interface": "state",
    "source": "dht_1",
    "nested_source":"temperature",
    "name": "Temperature too Hot",
    "frequency":"many",
    "thresholds": [
        {
            "comparison":"gte",
            "value":74
        }
    ],
    "actions": ["toggle.turn_on"]
}]

The configuration above would turn_on all toggles if the temperature was above 74.
