Assuming your scheduler can have shell script hooks attached to events,
I'd add something to send a "disable" command before it brings a node
down, and then re-enable as it comes back up. If the nodes are being
powered down without state being saved (eg, not suspending/resuming
themselves), then just disable "until OK", otherwise I'd use some
arbitrary future value.

Relevant tests will be blue (not green, as requested), but that will be
handled as a non-event for SLA purposes.

Separately, it might be a good idea to have a separate server-side test
that sends node state about each node to xymon independent of the node
itself. That test is a fine place to put logic as well.
