Hi,
I have a Homeassistant Yellow and want to integrate an evehome smart plug with matter support. I have set up the matter addon with matter-server and open thread border router. The thread integration is able to detect the network and I double checked the information in the thread addon and in the otbr web gui.
Adding the device via the companion app on my ios device does not work, because my ios device “requires a thread border router” as I dont have a matter compatible apple device (like apple tv).
Next, I tried to connect the smart plug via a python script using the python-matter-server package. This also doesnt work, but I observed the following logs
2023-05-04 14:54:21 core-matter-server chip.CTL[126] INFO Starting commissioning discovery over BLE

The yellow and the smart plug are ~1 meter apart from each other.
I have the bluetooth integration installed and it lists 1 device with the bluetooth address.
Is there a way to increase the BLE timeout?
I dont really know what I can do and I hope you can help me!
