Ah, I had only tried with 2.4 and not 5. SSID availability is another way to keep an AP from broadcasting the SSID using tags. However it doesn't turn off the radio. I've never tried it in a template scenario so I don't know if it's part of the local override options.
I do quite like the PDUs. They allow you to turn individual devices off an on. Some support schedules (so you can power cycle something at a regular time, or power things off out of hours). Some of the more expensive ones also include monitoring so you can see the amount of power each device is consuming.
