Z=wave power outlets all stopped

Here's a head scratcher.

I have 6 z-wave power outlets (3 HKZW-SO01 AND 3XNAS-WR02ZU)
I also have 8 multi sensors z-wave
and one ZW117 repeater

out of the blue, all of the outlets stopped working (no ack), but the multi sensors are all working.

I haven't changed anything. I've rebooted the indigo server computer. Still no dice. No ack error

Did the network optimization, no dice.

Any ideas?

Try re-syncing them in Indigo (in the device dialog for each). Does that work? If not, copy/paste the Event Log result.

Next, move one of them to be next to your Mac / Z-Stick and try it there. Does that work?

Lastly, if not, then try excluding the one that is next to the Mac from the Z-Stick, then re-include and re-sync it. Does that work?
