How are you determining your My Cloud is actually going to sleep?
This sleep problem is a vexing one for many of us. There are quite a few threads that cover various ways and methods people are trying to get their My Cloud to sleep for longer than 10 minutes at a time. There are several background services within the My Cloud that cause it to wake up at random times breaking the sleep cycle. Those services cannot be shut down through the Dashboard, instead one has to use SSH to connect into the My Cloud and disable or shut them down. There is also the issue of the My Cloud waking at 2am or 3am to check for firmware even though a user may have disabled the check for updates option.
Another user created a script one can run to see how often their My Cloud actually sleeps and for how long, it may surprise many to see how little their My Cloud sleeps in default configuration.
