Find a matter code without access to device

Hi

I have a plug socket which is behind a kitchen unit that i installed a matter smart plug into. At some point a change was pushed and the plug fell off the network.

Now i can get a pole in to reset the plug but i dont have the pairing code.

The plug is still showing in HA but not accessible.

Is there anyway to find the plugs pairing code or am i going to have to take my kitchen apart to find the code?

Thanks

What plug is it?
Onvis and Eve energy plugs also have the pairring code on the manual sheet.

its eightree

Don’t know that one, but see if there might be a sticker in the manual somewhere.

sadly there isnt one… guess im pulling my dishwasher out again
