Abstract

An asynchronous reporting mechanism for a remote device in a heating, ventilation and air conditioning environment. Using gateway information, such as a device address, report information may be sent to the user account, or using another approach, the information may be sent directly to the user. An asynchronous message may be sent without user intervention or request.

First claim

What is claimed is:

1. A gateway control system for residential equipment comprising:
a gateway device;
heating, ventilation and air conditioning (HVAC) equipment connected to the gateway device;
a remote access mechanism connected to the gateway device;
a first communication channel which provides a two-way synchronous connection between the remote access mechanism and the gateway device via an Internet connection; and
a second communication channel which provides a one-way asynchronous reporting mechanism from the gateway device to the remote access mechanism; and
wherein:
the gateway device is configured to communicate with a server via the first communication channel using messages sent during a data session within a round robin sequence of data sessions;
the server comprises a database, a web application and communication layers;
a web interface module interacts with the web application to display information and receive action from button events and
the communication layers are instanced in the server when user activity opens the data session on the web interface module;
the gateway device is configured to communicate with the server via the second communication channel using an asynchronous message sent outside of the data session; and
the gateway device is configured to send asynchronous messages to the server including information regarding components of the HVAC equipment via the second communication channel and the server is not configured to send asynchronous messages to the gateway device outside of the data session.

2. The gateway control system of claim 1 , wherein the data session is opened between the gateway device and the server using a check-in process.

3. The gateway control system of claim 1 , wherein virtually all messages between the gateway device and the server are sent during the data session.

4. The gateway control system of claim 1 , wherein the database in the server is used when in an absence of a data session between the gateway device and the server.

5. The gateway control system of claim 1 , wherein an asynchronous message is sent when information needs to be conveyed without a data session from the gateway device.

6. The gateway control system of claim 1 , wherein an asynchronous message ensures that reports about HVAC equipment are captured by the server a majority of the time.

7. The gateway control system of claim 1 , wherein the server is configured to send a response message to the gateway device after receiving a message sent by the gateway device.

8. The gateway control system of claim 1 , wherein transmission control protocol (TCP) is used by the gateway device for the asynchronous message.

9. The gateway control system of claim 1 , wherein the asynchronous message is sent in an encrypted mode.

10. The gateway control system of claim 1 , wherein the gateway device uses a first protocol encapsulated in an asynchronous structure for wireless access to the HVAC equipment.

11. The gateway control system of claim 10 , wherein faults and/or errors are sent using the asynchronous message.

12. A method for gateway control of residential equipment comprising:
connecting heating, ventilation and air conditioning (HVAC) equipment to a gateway device; and
connecting the gateway device to a remote access mechanism via a first communication channel which provides a two-way synchronous Internet connection;
monitoring the HVAC equipment;
sending a message reflecting a current state of the HVAC equipment to the server during the data session;
connecting the gateway device to a remote access mechanism via a second communication channel which provides a one-way asynchronous connection;
receiving a command at the gateway device reflecting a desired configuration or control state of the HVAC equipment from the server during the data session; and
detecting a fault and/or error; and
wherein:
the gateway device is configured to communicate with a server within a data session within a round robin sequence of data sessions;
the server comprises a database, a web application, and communication layers;
a web interface module interacts with the web application to display information and receive action from button events;
the communication layers are instanced in the server when user activity opens a data session on the web interface module;
the server is configured to receive messages from the gateway device and to send messages to the gateway device during the data session within the round robin sequence of data sessions; and
the server is further configured to receive asynchronous messages from the gateway device outside of a data session within the round robin sequence of data sessions, but is not configured to send messages to the gateway device outside of the data session within the round robin sequence of data sessions.

13. The method of claim 12 , wherein upon determining that a fault or error has been detected, the gateway device transmits an error message through the first communication channel in a presence of an open data session.

14. The method of claim 12 , wherein upon determining that a fault or error has been detected, the gateway device transmits an error message through the second communication channel in an absence of an open data session.

15. The method of claim 14 , wherein an asynchronous message is sent by the gateway device to the server in the absence of an open data session between the gateway device and the server without user intervention or request.

16. A gateway control system for residential equipment comprising:
a gateway device;
heating, ventilation and air conditioning (HVAC) equipment connected to the gateway device;
a remote access mechanism connected to the gateway device;
a first communication channel which provides a two-way synchronous connection between the remote access mechanism and the gateway device via an Internet connection; and
a second communication channel which provides a one-way asynchronous reporting mechanism from the gateway device to the remote access mechanism; and
wherein:
the gateway device is configured to communicate with a server via the first communication channel using messages sent during a data session within a round robin sequence of data sessions;
the server comprises a database, a web application and communication layers;
a web interface module interacts with the web application to display information and receive action from button events and
the communication layers are instanced in the server when user activity opens the data session on the web interface module; and
the gateway device is configured to communicate with the server via the second communication channel using an asynchronous message sent outside of the data session.

17. The gateway control system of claim 16 , wherein the server is configured to send a response message to the gateway device after receiving a message sent by the gateway device.
