Remote automated assistant component(s) generate client device notification(s) based on a received IoT state change notification that indicates a change in at least one state associated with at least one IoT device. The generated client device notification(s) can each indicate the change in state associated with the at least one IoT device, and can optionally indicate the at least one IoT device. Further, the remote automated assistant component(s) can identify candidate assistant client devices that are associated with the at least one IoT device, and determine whether each of the one or more of the candidate assistant client device(s) should render a corresponding client device notification. The remote automated assistant component(s) can then transmit a corresponding command to each of the assistant client device(s) it determines should render a corresponding client device notification, where each transmitted command causes the corresponding assistant client device to render the corresponding client device notification.

A connection maintenance method for an Internet of Things (IoT) device is disclosed in the present invention. The connection maintenance method includes establishing a virtual connection between the IoT device and a server, receiving a connection maintenance request from the IoT device, obtaining an identification code of the IoT device according to the connection maintenance request, transmitting a paging signal to the IoT device by using a first cycle according to the connection maintenance request to confirm whether the IoT device is alive, and when it is confirmed that the IoT device is alive, generating and transmitting a heartbeat packet carrying the identification code to the server by using a second cycle.

Multiple low cost individual sensors communicate with a server. A proxy sensor communicates with the server. The server periodically compares information from the individual sensors with information from the proxy sensor. The server validates and accepts information from individual sensors. The server changes gain and offset values for individual sensors providing information that is not validated by the comparing.

A novel underwater robot water quality data acquisition device includes a casing, a thruster group, an upper cabin, a lower cabin, a buoy cabin, an upper cabin tray, a lower cabin tray, a power supply assembly, a power conditioning module, a data acquisition control module, a water quality sensor assembly, and a wireless Internet of Things (IoT) module. The device can convert the power supply voltage required by each other module through the power management module. The data acquisition control module transmits signals to the water quality sensor assembly in a set timing sequence, performs real-time reading and processing of water quality data fed back from the sensor, and uploads the processed water quality data to the data platform through the wireless IoT module, thereby achieving the display and preservation of water quality data.

A network of wireless nodes collects data from a fluid tank or gas usage device sensor and uploads the data to the cloud or the Internet. The network allows for a temporary node to integrate into the network such that technicians can access the network without access to the cloud or internet. Data from the sensor may then be used by the system, either locally or remotely, to control or adjust one or more Internet of Things (IoT) devices based on the values of parameters such as tank fluid level or gas usage, etc.
