I have on of the Legrand Matter over WiFi dimmers, great devices. However the painters sprayed over the matter QR code and the numeric code. I already have the device registered in HA. I have several of these devices and maintain a spreadsheet of all the matter numeric codes for potential future use. My question is...
Is there a way to get the Matter numeric code from a device that is registered with HA?
Is it stored deep inside some file or database? I'm screwed if I ever have to re-register this device.
Thanks
