A device, which is intended to remotely control at least one operation of at least one appliance, includes an input interface module for receiving inputs from a user, and a communication module for sending to a management platform data which represent a control instruction activated by the user. Such a device can have universal remote control functionality, with an additional contextualization functionality.

An appliance is provided. The appliance includes a transceiver, and a processor configured to, based on an external appliance being identified to be adjacent to the appliance, receive arrangement state information of the external appliance through the transceiver, identify whether the appliance is a slave device controlled by the external appliance or a master device to control the external appliance based on the arrangement state information of the external appliance and arrangement state information of the appliance, based on the appliance being identified as the slave device, transmit a control authority to the external appliance through the transceiver, and based on the appliance being identified as the master device, request the control authority from the external appliance identified as the slave device through the transceiver.

An apparatus comprises a light source array, a communication interface, and a controller. The light source array comprises one or more directional light sources. The communication interface is configured to receive user data from at least one appliance, the user data indicative of an identity of a user. The controller is configured to analyze the identity of the user and activate the one or more directional light sources in response to the identity of the user.

An apparatus for aggregation of water condition at household appliances comprises a communication interface and a controller. The communication interface is configured to send a reporting message indicative of data collected by at least one appliance to a central server. The controller is configured to receive an analysis message from the central server. The analysis message indicates a condition of water from the at least one appliance or a condition of water in a geographic area associated with the at least one appliance. The controller is configured to provide an alert in response to the analysis message.

A voice controlled device comprises a plurality of microphones, a communication interface, and a controller. The plurality of microphones are configured to receive voice inputs from one or more users for operation of the voice controlled device. The communication interface is configured to receive sensor data from an external device, the sensor data describing an environment of the voice controlled device. The controller is configured to operate a first subset of the plurality of microphones in response to first sensor data and a second subset of the plurality of microphones in response to second sensor data.
