Means you went through the “Linux” installation method? All of the components (Mosquittio, Zigbee2mqtt) installed directly on the OS without virtualization?
What are the advantages of this? I guess slightly performance?
Also, where does deCONZ fit into all of this? It’s also installed on your separate PI?
I recommend using the ZigStar Stick v4. The stick works flawlessy with zigbee2mqtt out-of-the-box and is very powerful. And last but not least: Responsive devs and fast delivery after ordering.
For more information about Zigbee sticks look here.
I would recommend using your spare pi and just doing the bare metal install of zigbee2mqtt. Thus work best for me as I was able to move my spare pi around the house and in different configurations to see the best way to build a strong mesh between devices.
