Inaccessible Pi with Home Assistant OS after changing ISP

Installation Home Assistant OS
1

hello, i have a raspberry pi 4 model B, with Home Assistant Operating System. it has worked wonderfully for the past few weeks but today we changed ISP which means we also changed a router. the IP format changed from 10.0.0.x to 192.168.1.x,
and since ive set my pi to have STATIC IP of 10.0.0.5 now the router doesnt recognize it at all - even when connecting a lan cable directly to the router icant see it on the interface at 192.168.1.1
obviously the entire home assistant system is inaccessible now on the platform at http://homeassistant.local:8123/

the solution must be to remove the static ip configuration of the pi, but as i understand it cannot be done directly on the memory card in the configuration file and neither can i access the pi remoetly with commandline since it doesnt exist on the home network as of now. i dont know anything of how hooking a monitor to the pi would work like with HAOS and i dont have micro hdmi adapter anyway :frowning:

what can i do?

Just reverse what ever you did to give the pi a static IP.

It is always easier to give something a static IP via the DHCP server. This is normally the router. Then when you change the router the static iIP goes as well.

If you have a laptop or similar that has ethernet you can connect a network cable straight between them and set the laptop ip to a static ip in the 192.168.1.0 network.
