All of these support a single computer only, so if your home lab has multiple PCs you need a remote control KVM switch too. And separately a remote control power strip/outlet if you need that also.
KVM switches are relatively cheap[^1] so I'm surprised there isn't an integrated solution.

There are a few, like this add-on for PiKVM[1], a fully integrated version from Geekworm[2], and an as-yet unreleased 4-port IP KVM switcher from GL-iNet[3].
