Bluetooth receiver drivers

Post by jeffski10 » Sat Apr 17, 2021 6:37 pm

I've been looking to get some Bluetooth sensors feeding into my Home Assistant install so I can monitor my house plants. Adding on a USB bluetooth device works in that its recognised but the driver is missing. Has anyone been able to add such device or compile a driver in the past to get this working?
