Comment 1 for bug 1508741

A red power icon in the UI denotes that the power status could not be *queried*. This failure arises when trying to *change* the power state.

If the power change that fails was initiated as a result of a status change, e.g. when starting commissioning, the node should be transitioned to the corresponding failed state, e.g. failed commissioning. That will happen when the commissioning monitor times-out, but it may be that we can detect this failure sooner (or already do).

If the power change that fails was initiated by the user then the user is expected to see that the node did not power on or off and then investigate. A log entry is added to the node event log that will help.

This is not a bug.
