boolean

(async) meterReset(multiChannelNodeId) → {Promise.<unknown>}

Method that resets the accumulated power meter value on the node. It tries to find the root node of the device and then looks for the COMMAND_CLASS_METER.

Parameters:

Promise.<unknown>

onDeleted()

Remove all listeners and intervals from node

Inherited From:

(async) onSettings(oldSettings, newSettings, changedKeysArr) → {Promise.<T>}

Method that handles changing settings for Z-Wave devices. It iterates over the changed settings and executes a CONFIGURATION_SET in sync. If all succeed, it will resolve, if one or more fail it will reject with an error of concatenated error messages (to see which settings failed if more than one).

Parameters:
Name Type Description
oldSettings
newSettings
changedKeysArr
