So how are we looking after a few hours?
We are at 320 of the 540 devices previously logg d.
I expect this as some devices are off,...

I expect that there are so 'few' devices is that they get powered off at the end of the day, and have not been powered on as of yet to call home.

Now showing 405 devices connected.

That's higher than I would have expected, but SAR is what we need, not htop.

There we go, and still too high.

In some regard yes I would agree - However as part of the cycling, I have updated about 15 clients that were on the previous build to the latest. So that could be part of the increased CPU as it was pushing out the update.

CPU should not do much while pushing out an update. That's a pretty light CPU activity.
