People will buy intelligence from us on a meter'

We have governmental surveillance and we have surveillance capitalism. Surveillance capitalism works so well that governments are now very interested in the data they collect, which is alarming. Unfounded conspiracy theory: It's probably one of the reasons that governments don't seem interested in AI's regulation. If I had the proper equipment to run AI entirely local and efficiently so that the expenditure would justify it, I would.

    If you're already using node-red, the Wake On Lan node works well, and with node-red it's easy to trigger the magic packet based on whatever trigger condition you want.

    The only limitation I know is WOL doesn't work after a power outage, because the switch and RPI doesn't know where to find the target machine

    Thanks for the tips on reusable enterprise cards btw

    maybe, but the pi does not need to know that, only the mac address and the interface. the switch doesn't need to know either because it's a broadcast frame, it's forwarded to all cables. the problem sometimes is that if you configure WOL from linux, the network adapter will probably forget on power cycling that it is supposed to react to magic packets. I think not all hardware is susceptible to that, but even then it could help to configure WOL in the BIOS

    Maybe something else going on then, but ive never gotten WOL to work after a blackout when there's two switches between sender and receiver. After powering up the receiver once, WOL works again

    Switches probably need to figure out which way a particular MAC is (unlike a hub, which just express everywhere). That's the switching part. If they power off, the tables will be empty.

    Yeah that was my assumption. But I hadn't considered WOL being broadcast, so now I'm not so sure. I would assume it's broadcast on both IP and Ethernet layer. It's time to do some wiresharking :)

    I don't think WoL works over IP. In my mind it's lower (LAN, e.g. ethernet) level. But if it used IP, you'd need to get ARP going before it routes. An "offline" network chip could probably manage that, though.

    I'm curious to know what you find. Wireshark is always fun and fun and enlightening. :)
