1. A system for humidifying an indoor space, the system comprising:
a nebulizer unit configured to create a mist for humidifying the indoor space;
an air circulation unit configured to provide air to the nebulizer unit;
a water supply component configured to control water flow from a water source to the nebulizer unit;
a first sensor configured to determine data regarding a characteristic of the nebulizer unit; and
a controller operably coupled to the nebulizer unit and the first sensor, wherein the controller is configured to:
receive first data associated with operation of the nebulizer unit from the first sensor, the first data comprising a plurality of measurements;
dynamically determine a threshold indicative of a failure state of the nebulizer unit by, at least in part:
determining an expected baseline for the first data during operation of the system; and
setting the threshold based on the expected baseline for the first data;
compare each of the plurality of measurements of the first data associated with operation of the nebulizer unit to the threshold;
in response to a determination that a predetermined number of the plurality of measurements of the first data associated with the operation of the nebulizer unit satisfy the threshold, determine existence of the failure state for the nebulizer unit; and
in response to determination of the existence of the failure state, initiate a remediation action with respect to the nebulizer unit,
wherein the remediation action comprises modifying pulse modulation of a plurality of nebulizers other than the nebulizer for which the failure state has been determined.
