Claim of US Patent No. 10,694,608

1. A load control device for controlling an amount of power to an electrical load in a zone, the load control device comprising:a microphone for receiving voice commands;
an occupancy sensor for detecting occupancy in the zone;
at least one communication circuit;
a controllably conductive device configured to control the amount of power to the electrical load; and
a control circuit operably connected to the microphone, the at least one communication circuit, and the controllably conductive device, the control circuit configured to:
receive a voice command via the microphone;
determine, based on a signal from the occupancy sensor, whether the zone is occupied;
based on determining that the zone is not occupied, do not transmit the voice command to a voice service;
based on determining that the zone is occupied, transmit via the at least one communication circuit the voice command received via the microphone to a voice service;
receive a response from the voice service;
interpret the response to determine a command;
interpret the response to determine whether the response comprises an indication of a zone;
in response to determining that the response comprises the indication of the zone, determine whether the indication of the zone matches the zone in which the load control device is located;
in response to determining that the indication of the zone matches the zone in which the load control device is located, control the controllably conductive device to control the amount of power to the electrical load in response to the command; and
in response to determining that the indication of the zone does not match the zone in which the load control device is located, do not control the controllably conductive device in response to the command.
