Can't re-add deleted device. Trying to add a NOC for a fabric that already exists

Hey Guys/Gals,

I deleted a device from matter, now when I try to re-add it I get the below.


2025-05-13 17:56:38.710 (Dummy-2) CHIP_ERROR [chip.native.CTL] Error on commissioning step 'SendNOC': 'src/controller/CHIPDeviceController.cpp:1712: CHIP Error 0x0000007E: Trying to add a NOC for a fabric that already exists'

That means the device itself still is paired with your fabric.

If your device is part of a different Matter ecosystem, you may be able to remove the Home Assistant fabric from there (e.g in Google Home there is “Linked Matter apps & services” in the device settings, where you should be able to find Vendor ID 134B (Nabu Casa) along with the name of your Home Assitant installation. You can then remove the particular fabric information from the device).

If you don’t have that device connected to another Matter fabric, try factory reset it.

That was it! Thank you! I have it on my Apple Network also, removed Nabu Casa homeassistant from it and re-added it. Thank you! Still learning matter!
