I have hassio running on Pi4. I have Z-Wave dongle and it was working well on USB 2.0. ( Z-Wave.Me USB Stick incl. Z-Way Controller Softw - Z-Wave Plus).
Then I bought Wireless Zigbee CC2531 and flashed CC2531_DEFAULT_20190608.
I installed MQTT broker.
Now Z-Wave is not working anymore. Why they have conflict?
Now Zigbee2MQTT is working but z-wave not more. Why
