A system for monitoring a building automation system (BAS). The systems may include a device to report data, a memory having an application that requires that the data from the device be reported at least at a minimum frequency, and a controller to receive the data from the device at least at the minimum frequency and use the application and the data to determine an operational status of a component of the BAS.

Building automation system monitoring

A method of controlling an HVAC system can include receiving audio that includes a predefined trigger phrase followed by a voice command to change a set point temperature of the HVAC system to a requested set point value, converting the audio into a natural language audio stream, identifying the predefined trigger phrase in the natural language audio stream, transmitting a part of the natural language audio stream that includes the voice command to a remote web service for identifying the voice command therein, receiving a first building control device command generated by and from the remote web service at a building control device when the requested set point value is within a predetermined range, and receiving a second building control command generated by and from the remote web service at the building control device when the requested set point value is outside of the predetermined range.

Devices and methods for interacting with an HVAC controller

A building automation system may adjust operation of a building system based upon information regarding the relative location of one or more users of the building automation system. In some embodiments, a mobile device having location services for determining a location of the mobile device may provide this information. A mobile device may include a user interface, a memory for storing two or more predetermined geo-fences each defining a different sized region about a home of a user of the mobile device and a controller operatively coupled to user interface and the memory, the controller configured to accept a selection of one of the two or more predetermined geo-fences via the user interface. The controller may report when the location of the mobile device crosses the selected one of the two or more predetermined geo-fences to a remote device. Other geofencing approaches are also described.

Building automation system with geo-fencing

A mailbox data storage mechanism for a remote device in a heating, ventilation and air conditioning environment. The mechanism, as a part of a gateway device and acting as a citizen of the heating, ventilation and air conditioning environment, may collect system information regularly and maintain a copy of the latest data locally which can be a response to external access requests in time at any moment. The mechanism may limit the latency for external access and improve user experience. The mechanism may help satisfy multiple interfaces.

Mailbox data storage system

A building automation system may be controlled in response to a natural language voice message. The natural language voice message may be recorded and then sent to a voice command manager via a network. The natural language voice message is then translated into a command recognizable by a building automation controller of the building automation system. Voice recognition software may be used to create a natural language text based message from the recorded natural voice message, and the natural language text based message may then be translated into the command recognizable by the building automation controller. In response to the command, the building automation controller may perform the desired action.

Devices and methods for interacting with a control system that is connected to a network

A call for humidity signal may activate a water valve of a humidifier to cause water to flow onto a humidifier pad within the humidifier. In some examples, a controller may activate the water valve in a pattern such that most of the water evaporates, rather than flowing to a drain system, yet still provides the requested humidity level. In some examples, the controller is configured to cause the water valve to deliver water to the humidifier pad in a water delivery pattern having a controlled period and a controlled duty cycle.

Humidifier with water valve control

An HVAC controller may be controlled in response to a natural language audio message that is not recognizable by the HVAC controller as a command, where the natural language audio message is translated into a command recognizable by the HVAC controller. The HVAC controller may be a thermostat including a housing that houses a temperature sensor, a microphone, and a controller. The controller may identify a trigger phrase in an audio stream provided by the microphone. In response to identifying the trigger phrase, the controller initiates processing of the audio stream to identify a command following the trigger phrase and to generate a command understandable by the thermostat that instructs the controller to perform the identified command. The controller then executes the generated command understandable by the thermostat. A user may communicate with the thermostat via the microphone of the thermostat and/or a remote device having a microphone.

A master HVAC schedule for an HVAC controller may be stored on an external server accessible over a computer network. The external server may maintain the master HVAC schedule, and may translate a portion of the master HVAC schedule into a basic HVAC schedule that is executable by an HVAC controller. The external server may deliver the basic HVAC schedule to an HVAC controller according to a predetermined schedule. In some cases, the external server may deliver an updated basic HVAC schedule to the HVAC controller in response to a user initiated change made to the master HVAC schedule or upon restoration of a lost network connection between the HVAC controller and the external server.

HVAC controller having a network-based scheduling feature

An improved humidifier system for adding humidity to an air stream of an HVAC system. The humidifier system includes an air path that is configured to accept air from a first HVAC duct and return air to a second HVAC duct. A damper is disposed in the air path to selectively substantially block the flow of air in the air path, or to substantially not block the flow of air in the air path. In some cases, the damper may be a motorized damper, and the humidifier system may include a controller that is configured to cause the motorized damper to not substantially block the flow of air in the air path during a call for humidifier operation, and to substantially block the flow of air in the air path after the call for humidifier operation ends. Alternatively, the damper may be manually actuated, and an HVAC controller may be configured to notify when the damper should be moved (e.g. between seasons).

Bypass humidifier with damper control

Methods and systems for indicating a status of an air filter of an HVAC system may include receiving a measure that is related to an amount of flow restriction presented by the air filter in an HVAC system, using the measure to determine whether the air filter does not need replacing, the air filter needs to be replaced soon, or the air filter should be replaced now, and displaying on a display of an HVAC controller an air filter status indicator, wherein the air filter status indicator includes a stop-light metaphor. In one example, the air filter status indicator may display a green color when the air filter does not need replacing, display a yellow color when the air filter needs to be replaced soon, and display a red color when the air filter should be replaced now. In some cases, the air filter status indicator may also include a qualitative term indicative of the current status of the air filter.

Filter change alert system for an HVAC system

A clean air filter may be used to set an air filter change threshold value for an air filter monitor installed in an HVAC system. The air filter change threshold value may be used to determine a status of an air filter (e.g., clean or dirty).

Method and systems for setting an air filter change threshold value in an HVAC system

A blocking panel may be used to set an air filter change threshold value for an air filter monitor installed in an HVAC system. The air filter change threshold value may then be used to determine a status of an air filter (e.g., clean or dirty).
