You can start the fan from a script using this HTTP request:
/data_request?id=action&DeviceNum=X&serviceId=urn:micasaverde-com:serviceId:VeraConnectWWN1&action=StartFan&Duration=15
or this Luup function:
luup.call_action("urn:micasaverde-com:serviceId:VeraConnectWWN1", "StartFan", { ["Duration"] = "15" }, DEVICE_ID)
Duration can be any of these values:
15, 30, 45, 60, 120, 240, 480, 960
Currently this is all the fan control the Nest API exposes. There aren't commands to start the fan for an undefined period of time, to stop the fan, to control its intensity or to schedule its run.
We'll implement additional features as the Nest API evolves over time and gives us more control over the thermostat functions.
