Hello,
I tried to setup the Voice Preview Edition device in a seperate wifi that has no internet connection and no dhcp. I set the static ip address on installation, but the setup via bluetooth doesnt work.
I have now set it up in my normal wifi, but I want to move it now, but can’t see any way to change the configuration.
I am running home assistant and esphome in docker.
Thx in advance 
I solved it.
I installed the following home-assistant-voice-pe/home-assistant-voice.yaml at 35cf95aed4c30887f5300245033d809077cb1005 · esphome/home-assistant-voice-pe · GitHub and adding the manual ip and settings. Flashing it via usb works (just make sure that your /dev/… device has the right permissions).
Look at these settings for wifi for manual ips and the whole link for wifi
