Problems with Z-Wave JS integration and Razberry Board

[RickKramer (Rick Kramer - Jansen)]

Razberry (Zwave) Board is not recognized after HassOS 4.8

Not sure about that. Setting BT to miniUART should allow foth BT and GPIO at the same time: /boot/config.txt: dtoverlay=miniuart-bt force_turbo=1 The 1st line switches BT to the miniUART and the 2nd line is needed with miniUART BT to set the VPU core clock to a fixed frequency, this is required based on https://www.raspberrypi.org/documentation/configuration/uart.md / UARTs and Device Tree -section, 3rd chapter.
