SkyConnect Multi-PAN + SR-ZG2833PAC-FOH (Sunricher Push Button Coupler C4) not working

For reference, it will need a ZHA Device Handler (a.k.a. quirk for ZHA) so post all information you can to the existing device support request for that device on GitHub → [Device Support Request] SR-ZG2833PAC-FOH (Zigbee Push-Button Coupler) · Issue #2426 · zigpy/zha-device-handlers · GitHub

Follow how-to about custom ZHA Device Handlers (a.k.a. quirks) → https://www.home-assistant.io/integrations/zha#how-to-add-support-for-new-and-unsupported-devices

You will need to pair the device and then provide both “Device signature” and “Diagnostic information”.
