Hello everyone,
after setting up an OTBR & Matter in Home Assistant, I cannot add a device.
My infrastructure:
- Home Assistant as a VM under Proxmox
- VM external with IP 192.168.20.151
- SMLIGHT - SLZB-07 passed through as a USB device and is recognized
(/dev/serial/by-id/usb-SMLIGHT_SMLIGHT_SLZB-07_…) - Android phone with IP 192.168.130.47
- Networks are routed via an OpenWRT router (192.168.1.1)
What I’ve done:
Hardware: - SMLIGHT - SLZB-07 USB stick (with Matter firmware)
- Installed OTBR under Add-ons
- Added Thread under System Devices & Services
- Enabled Preferred Network (ha-thread-fd7c) under the gear icon
- Used login credentials for Android & iOS
- On the Android phone, in the Home Assistant app under Companion App Troubleshooting,
Synchronizing Thread Access Data - Aqara FP300 cannot be added via Matter (See attachments)
What else can I check or change? I would appreciate your support.

Could problems arise if the Home Assistant OS is on a different network than the Wi-Fi devices?
