A controller circuit is configured to receive, from a first device, a first node voltage measured at a first node by the first device at a first time when a first current flows between the first node and a second node and receive, from a second device, a second node voltage measured at a second node by the second device at a second time when a second current flows between the first node and the second node, wherein the first time is different from the second time. The controller circuit is further configured to, responsive to a determination that the first current corresponds to the second current, calculate, using the first node voltage and the second node voltage, a resistance value for one or more electrical components electrically connecting the first node and the second node.

Resistance measurement for measurements from multiple devices

In some examples, a device includes a memory configured to store a pre-warning threshold level for a parameter of a power switch. The device also includes a logic circuit configured to receive a signal from a controller and set the pre-warning threshold level in response to receiving the signal from the controller. The logic circuit is also configured to determine that a magnitude of the parameter of the power switch does not satisfy the pre-warning threshold level. The logic circuit is further configured to output an alert to the controller in response to determining that the magnitude of the parameter does not satisfy the pre-warning threshold level.
