Hi @derekangl I have added code to manage sleeping node in v2. But I have not tested. Can you please verify the status and let me know?

Code changes: https://github.com/mycontroller-org/server/commit/ffe7ab56ab2cacf086180d83cb79fb67ba97c911

There is label will be added in to the sleeping node. sleep_node = true, if it is not added, you have to add this label manually
