Communication device, communication adaptor, communication system, communication parameter response method, and program

A non-transitory computer-readable recording medium storing a program configured to cause a communication adapter for connecting with an electrical device to function as:

• a response time measurer configured to measure an amount of time that elapses from when a control instruction is sent to the electrical device until a response to the control instruction returns from the electrical device;
• and
• a communication parameter responder configured to, upon receipt from a control device of a communication parameter request-command, acquire and save a current operation state of the electrical device, send to the electrical device a control instruction corresponding to content of the communication parameter request-command, and send as a communication parameter to the control device, an amount of time that elapses until a response to the control instruction returns measured by the response time measurer,
• wherein the communication parameter responder is further configured to, upon return from the electrical device of the response to the control instruction, send to the electrical device a control instruction for reverting to the operation state,
• the communication adapter being configured to electrically connect to the electrical device through a standardized serial communication interface, the electrical device being a household appliance.

A communication method for connecting a communication adapter to an electrical device comprising:

• measuring, by a response time measurer, an amount of time that elapses from when a control instruction is sent to the electrical device until a response to the control instruction returns from the electrical device;
• and
• acquiring and saving, by a communication parameter responder, upon receipt from a control device of a communication parameter request-command, a current operation state of the electrical device, sending to the electrical device a control instruction corresponding to content of the communication parameter request-command, and sending as a communication parameter to the control device, an amount of time that elapses until a response to the control instruction returns measured by the response time measurer,
• the communication parameter responder further, upon return from the electrical device of the response to the control instruction, sending to the electrical device a control instruction for reverting to the operation state,
• the communication adapter being configured to electrically connect to the electrical device through a standardized serial communication interface, the electrical device being a household appliance.
