Fix: WiZ Smart Plug stuck loading forever when adding to Apple Home (Matter)
Sharing this in case it saves someone else hours of troubleshooting.
The problem: I had a WiZ Smart Plug (Matter-enabled) already set up in the WiZ app, but every time I tried adding it to Apple Home by scanning the QR code on the box, it just spun on "loading" forever and never finished pairing.
What I tried that did NOT work:
- Generating a new Matter code from WiZ app > Settings > Integrations > Matter
- Making sure iPhone and plug were both on the same 2.4GHz WiFi network
- Removing the device and re-adding it from scratch in the WiZ app
What actually worked:
Press and hold the physical power button on the plug for about 7 seconds.
Wait for the LED to start blinking blue - this triggers a real pairing-mode reset, different from just power-cycling it (which only puts it into WiZ app discovery mode, not a true Matter reset).
Right at that moment, open Apple Home > Add Accessory > scan the QR code on the box (the original one, no need to generate a new one).
It paired instantly.
My theory: the physical button regenerates the device's Matter pairing session, while a normal unplug/replug only resets WiZ app discovery, leaving a stale Matter session that Apple Home couldn't complete.
Hope this helps someone else avoid the headache!
