Hello community,
I have successfully put into operation an old IPAD2 with iOS 9.3.5 via VNC. For this I set up a docker container Firefox-Desktop-G3. I connected to this container from the computer via VNC to log in to the Home Assistant. Then press F11 for full screen mode. I use VNC Viewer on the ipad and can therefore use home assistant on the IPAD2.
I hope it helps some. Sorry for the bad english. I used google translate.
