Derivative sensors are updated upon changes of the **source sensor**. +For sensors that reset to zero after a power interruption and need a "non-negative derivative", such as bandwidth counters in routers, or rain gauges, consider using the [Utility Meter](/integrations/utility_meter/) integration instead. Otherwise, each reset will register a significant change in the derivative sensor. + {% include integrations/config_flow.md %} {% configuration_basic %} Name:
