Hey all, I'm looking to build a couple dashboards out around my house. I've done this before with rokchip boards and they are... fine, but not great. Is rpi the best option right now? Are there alternatives you really like? I'd like to keep it a single board to easily mount behind things where it doesn't take up a lot of space, and I won't lie I like the DIY feeling of it over something like a thin client.

Pls, provide some proof for those numbers. The 'under 5W mark' gets often claimed but i still have not seen a valid proof (a simple measurement with a wattmeter) of it other than some spec sheet.

The overhead does not matter really. USB 5V power supplies are cheap and efficient these days, yes you need to look out for an efficient one but even one with only 50% efficiency (which is really really bad) would only add 1W to the (lower than) 2W power in idle. That would still result in lower power in idle.

Anecdotally my NUC runs 2 linux VMs and a couple of LXCs, so it's never truly idling, and pulls an average of 7.5W.

Thank you. Would love to see the true idle. The difference between idle and light load is often not that high. I imagine the CPU supports virtualization?

And would also love to know some more specs of the NUC.

It has an older i3 quadcore @ 3ghz max with 16gb ram and 1tb nvme, can't remember the model number.

I think idle without any VMs or containers running is around 6.5W, so no it's not much lower.
