Identifying errors with home HVAC systems and notifying the homeowner of the error and potential remedial steps can be useful. In some embodiments, a method is provided including receiving, at an electronic device, a temperature value and an airflow value from sensors located at a vent grate of the HVAC system. A temperature delta value can be calculated using the temperature value and an ambient temperature value. The temperature delta value can be compared with predetermined temperature delta threshold value. The airflow value can be compared with predetermined airflow threshold value. Based on comparing the temperature delta value step and/or the comparing the airflow value step, an error with the HVAC system can be identified. A notification of the error and subsequent potential remedial steps can be sent from the electronic device to the homeowner.

1. A method comprising: determining, at a television receiver of a home automation system, a predetermined temperature delta threshold value and a predetermined airflow threshold value for a Heating, Ventilation, and Air Conditioning (HVAC) system;storing, by the television receiver, the predetermined temperature delta threshold value and the predetermined airflow threshold value in a home automation settings database;receiving, at the television receiver, a signal from the HVAC system indicating that the HVAC system is actively running;receiving, at the television receiver while the HVAC system is actively running, a temperature value from a temperature sensor located at a vent grate of the HVAC system, the temperature value indicating a temperature of the air emitting from the HVAC system;receiving, at the television receiver while the HVAC system is currently running, an airflow value from a pressure sensor located at the vent grate of the HVAC system, the airflow value determined by a pressure of the air emitting from the HVAC system;calculating, at the television receiver, a temperature delta value based on the temperature value and an ambient temperature value;comparing, at the television receiver, the temperature delta value with the predetermined temperature delta threshold value;comparing, at the television receiver, the airflow value with the predetermined airflow threshold value;identifying, by the television receiver, an error with the HVAC system, the identifying the error comprising: determining, by the television receiver, that the airflow value is an acceptable value based on comparing the airflow value to the predetermined airflow threshold value,determining, by the television receiver, that the temperature delta value is below the predetermined temperature delta threshold value, wherein the predetermined temperature delta threshold value indicates a pilot light failure, andidentifying, by the television receiver, that the error with the HVAC system is a pilot light failure based on the determining that the airflow value is an acceptable value and determining that the temperature delta value is below the predetermined temperature delta threshold value; andsending, by the television receiver, a notification of the error to a device of a user alerting the user that the error with the HVAC system is a pilot light failure and instructing the user to relight the pilot light. 2. The method of claim 1, further comprising: receiving, at the television receiver, a known good airflow value from the pressure sensor located at the vent grate of the HVAC system, the known good airflow value determined by the pressure of the air emitting from the HVAC system during a known good operating cycle;receiving, at the television receiver, a known good temperature value from the temperature sensor located at the vent grate of the HVAC system, the known good temperature value indicating the temperature of the air emitting from the HVAC system during a known good operating cycle;calculating, by the television receiver, the predetermined airflow threshold value based on the known good airflow value; andcalculating, by the television receiver, the predetermined temperature delta threshold value based on the known good temperature value. 3. The method of claim 1, wherein the notification is displayed on a television. 4. The method of claim 1, wherein the temperature sensor is a first temperature sensor, the method further comprising: receiving, at the television receiver, the ambient temperature value from a second temperature sensor located at the vent grate of the HVAC system. 5. The method of claim 1, further comprising: receiving, at the television receiver, the predetermined temperature delta threshold value and the predetermined airflow threshold value from a television service provider. 6. A system, comprising: a temperature sensor, the temperature sensor being located in a vent grate of a Heating, Ventilation, and Air Conditioning (HVAC) system and configured to measure a temperature of air emitting from the HVAC system;a pressure sensor, the pressure sensor being located in the vent grate of the HVAC system and configured to measure a pressure differential of air emitting from the HVAC system;a storage device; anda television receiver of a home automation system communicatively coupled to the temperature sensor, the pressure sensor, and the storage device, the television receiver comprising: one or more processors; andmemory communicatively coupled with and readable by the one or more processors and having stored therein processor-readable instructions which, when executed by the one or more processors, cause the one or more processors to: determine a predetermined temperature delta threshold value and a predetermined airflow threshold value;storing the predetermined temperature delta threshold value and the predetermined airflow threshold value in the storage device;receive a signal from the HVAC system indicating that the HVAC system is actively running;receive a temperature value from the temperature sensor while the HVAC system is actively running;receive an airflow value from the pressure sensor while the HVAC system is actively running;calculate a temperature delta value based on the temperature value and an ambient temperature value;compare the temperature delta value with a predetermined temperature delta threshold value, wherein the predetermined temperature delta threshold value is stored in the storage device;compare the airflow value with a predetermined airflow threshold value, wherein the predetermined airflow threshold value is stored in the storage device;identify an error with the HVAC system, the identifying the error comprising: determine that the airflow value is an acceptable value based on comparing the airflow value to the predetermined airflow threshold value,determine that the temperature delta value is below the predetermined temperature delta threshold value, wherein the predetermined temperature delta threshold value indicates a pilot light failure, andidentify that the error with the HVAC system is a pilot light failure based on determining that the airflow value is an acceptable value and determining that the temperature delta value is below the predetermined temperature delta threshold value; andsend a notification of the error to a device of a user alerting the user that the error with the HVAC system is a pilot light failure and instructing the user to relight the pilot light. 7. The system of claim 6, wherein the memory further has stored therein processor-readable instructions which, when executed by the one or more processors, cause the one or more processors to: receive a known good airflow value from the pressure sensor located at the vent grate of the HVAC system, the known good airflow value determined by a pressure of the air emitting from the HVAC system during a known good operating cycle;receive a known good temperature value from the temperature sensor located at the vent grate of the HVAC system, the known good temperature value indicating a temperature of the air emitting from the HVAC system during a known good operating cycle;calculate the predetermined airflow threshold value based on the known good airflow value; andcalculate the predetermined temperature delta threshold value based on the known good temperature value. 8. The system of claim 6, wherein the notification is displayed on a television. 9. The system of claim 6, wherein the temperature sensor is a first temperature sensor, and wherein the memory further has stored therein processor-readable instructions which, when executed by the one or more processors, cause the one or more processors to: receive the ambient temperature value from a second temperature sensor located at the vent grate of the HVAC system.
