Residential device feedback system and method

Systems (600) and methods are described, which relate to internet-of-things (IoT) feedback systems, in which data received from a given IoT device (200) may be analyzed by a controller (602) and used as a basis for controlling another IoT device and/or sending an alert to a user. The controller may activate a dehumidifier (904) upon detecting activation of a sump pump (906). The controller may monitor water level data and alert a user and/or request maintenance of the sump pump upon detecting the water level exceeds a threshold. The controller may monitor dishwasher data to detect suboptimal performance of a dishwasher, in response to which the controller may instruct valves of a manifold (628) and water heater (622) to close to isolate the dishwasher, and instruct a water softener (6520 to elevate salt levels of softened water during a self-cleaning cycle of the dishwasher.
