I have my Pi running with a ConBee usb stick and deCONZ. I have around 10 xiaomi devices connected along with 8 Ikea trådfri LED spots and the only gateway / hub I have is the ConBee usb stick running via deCONZ. I have no Phillips HUE products but I believe they will connect to deCONZ without problems and so far it has been working flawlessly.
The range is good but I had to plug in a xiaomi smart socket to extend the range for the ikea led spots which is setup in my garage.
