Follow the SD Card preparation step and insert that card into Raspberry Pi 4, then, without plugging anywhere, power it from USB-C port.

Then follow the Wi-Fi Configuration.

The board will connect to your Wi-Fi and will start downloading ~3GB container image which will definitely take some time.
While waiting, I recommend figuring out IP of the mower from router DHCP leases and opening SSH connection.

Running sudo systemctl status --no-pager --full --lines 1000 openmower should display something reassuring.

bunch of PARAMETERS/NODES and view exception due to missing literally all the hardware

If you are lazy, just wait 5-10 minutes and check that http://openmower.local:8080 or http://<your-openmower-IP>:8080 is accessible.
If it’s not, you need to SSH and check the logs with sudo journalctl --follow --unit openmower.
Usually a problem would be bad config file.

If you got to the webapp - you are good. Plug the Raspberry Pi back to mainboard.
