It can also detect chassis intrusions.
Two problems: - AFAIK there is no standard system to actively use those voltage sensors to detect potentially harmful situations and take measures (not even logging weird voltage events seems to be standard). - My understanding is that the problems related to power supplies which we'd like to catch are related to *very* transient variations on input voltage, and AFAIK the infrastructure around those sensors just isn't equipped to detect such variations. === Stefan
