piKVM was discovered on my network and configured and the over subsequent refreshes and restarts the same device is discovered again and asking to be configured. The hostname and IP of the discovered piKVM is the same as the currently configured one.

This is a known issue and it is due to the fact that I refuse to try to brute force existing data to detect if we've already connected to this device previously. Theoretically this technique could be used to capture your device password. I have submitted a PR to PiKVM to implement Avahi ZeroConf and will be able to detect devices automatically this way.

Is there a way on the HA side to check to see if a device at that IP/hostname/MAC address is already configured?

adamoutler commented 1 week ago

Yes IP is possible but MAC is not. However, I've submitted a PR and discussed with the PiKVM dev about implementing ZeroConf. Once that's been implemented, I plan to rewrite the entire config flow and ditch DHCP config. With ZeroConf you can expect a much better flow.

The Hostname of PiKVM is always pikvm unless it's been changed so that's not a good detection method.

adamoutler commented 1 week ago

As a workaround you can change the PiKVM hostname to something other than pikvm*. Eg. mypikvm. This will cause DHCP to stop detecting the device. Or you can set your username/password to default so it will auto-add the device.
