LAN mode works well with home assistant and some HACS Bambu integration. Takes some setup but then you get real time camera feed and all the nice sensors for temp, humidity, including any AMS you have. I connected mine to Bambu server for the app just to see what it does, and my home assistant setup still works over LAN. Great printers and for now offline modes work well.
2nd this, I have my X1C blocked on any inet access, LAN only, it’s a very nice piece of hardware with questionable software :/
