       | I have a JetKVM (https://jetkvm.com/) and it's been absolutely
       | fantastic. I'm still waiting on the ATX expansion board, but the
       | core unit is used to monitor my homeserver.

           | 
           | I think it would be simpler to buy a network PDU (or iot
           | plugs) for your use case, assuming the computers can be set

       | Alas, try as I might (I just tried again last night for a couple

         | 
         | If you just need power control and your motherboard supports
         | it, I've seen that some people use smart plugs and enable a
         | setting in their BIOS that turns on the computer whenever it

           | instead the PC turns on whenever it detects power.
           | 
           | I have it connected to an Eve Energy so I can track power
           | usage, and that turned into a good remote way to turn it on.
           | 
           | Then with a Tailscale, I remote into it easily.
           | 
           | The downside is that I can't shut it down remotely without
           | knowing when exactly to also turn off the plug. I could
           | create some automation, but it takes about 2 seconds being
           | off before turning on again.

         | power via the USB HID port instead of the dedicated PD. In my
