Node-RED node to simulate home occupancy by intermittently activating and deactivating devices (e.g. lights) at random intervals.
You can configure a time window during which the node should eject random ON / OFF messages (e.g. 07:00 - 14:30), the duration of ON times (min / max) as well as how many ON times (min / max) should be randomly scheduled.
Properties can be configured statically using the editor or dynamically by injecting a message with a config object.
You can overwrite the static configuration at runtime by passing a config object as msg.payload to the presence-faker node. All attributes are optional. minDuration and maxDuration are expressed in seconds.
{
"windowBegin": "00:00",
"windowEnd": "23:59:59",
"minDuration": 60,
"maxDuration": 600,
"minCount": 10,
"maxCount": 25
}If the presence-faker node is currently enabled, this will instantly create a new schedule with the new configuration being applied. Otherwise the changes will take effect as soon as the presence-faker node gets enabled.
You can combine the presence-faker node with the suncron node in order to dynamically set windowBegin and/or windowEnd based on the position of the sun:
