Raspberry Pi 4
GREEN or GREEN/RED, webapp is not opening, cannot move mower via controller. We go step by step.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.
🔑 Default SSH credentials
Username:openmower, password: openmower.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.
