20190238358 | AUTOMATIC DEVICE ORCHESTRATION AND CONFIGURATION - Techniques and system configurations for generating and implementing recipes and scripts to enable the orchestration of actions, activities, and configurations within smart devices and device networks (including the Internet of Things “IoT” network topologies) are described herein. In an example, a method for smart device orchestration and configuration includes: obtaining an orchestration recipe that defines a sequence of actions to be performed among multiple types of smart devices; activating the orchestration recipe for use upon multiple smart devices associated with a user, based on at least one condition to perform the sequence of actions; associating the orchestration recipe with respective configurations of the multiple smart devices associated with the user; and initiating the orchestration recipe, to cause the sequence of actions to be performed with the multiple smart devices, including via cloud-based device services that control the multiple smart devices associated with the user. | 2019-08-01 |
20190238359 | Systems and Methods for Wireless Monitoring of Sump Pumps Based on Geographic Location - Embodiments of the invention provide a system for adapting a sump pump for wireless communication. In some embodiments, a system for adapting a sump pump with a serial communication port for communication with a user via a remote server, an internet connection, and internet enabled device is provided, the system comprising: a wireless gateway device connected to a router; and a wireless adapter connected to the serial communication port, comprising: a gateway node; a transceiver; and a processor programmed to: establish a wireless connection with the wireless gateway; receive a first message from the sump pump; cause the gateway node to modify the first message; cause the first modified message to be transmitted to the remote server via the wireless gateway; receive a second message from the remote server; modify the second message for output to the sump pump; and transmit the second modified message to the sump pump. | 2019-08-01 |
20190238360 | SMART DEVICES FOR HOUSEHOLD CONSUMABLES - A smart device for a household consumable includes at least one load sensor configured to measure a current load of a household consumable being supported by the smart device and a processor configured to compare the current load to a previously measured load to determine whether to increment one of a plurality of consumption event counters. The processor is configured to periodically transmit data located in the plurality of consumption event counters. | 2019-08-01 |
20190238361 | Cable Media Converter Management Method, Apparatus, and System - A cable media converter (CMC) management method, including receiving, by a CMC controller by using a management channel, a second message packet sent by a CMC, where the second message packet has an identifier of the CMC and configuration file information of a cable modem (CM), and where the identifier of the CMC uniquely identifies the CMC, and determining, by the CMC controller according to a locally saved correspondence between an optical line terminal (OLT) and a CMC, an OLT corresponding to the CMC identified by the identifier in the second message packet, and sending the configuration file information in the second message packet to the determined OLT. | 2019-08-01 |
