I started using rumble.run when it was under its first iterations at home to do local network discovery. It's now evolved to
https://www.runzero.com/ and still free for small home networks (/19? and 100 discovered devices) which I am trying to keep under!
Only hassle is running around the house turning on all the IoT devices to get them enumerated (and to avoid DHCP contention when I've done a static assignment somewhere...)
