Hi reachrao,

What method did you use to install Grafana? Did you follow [the installation guide for Raspberry Pi in our docs](https://grafana.com/tutorials/install-grafana-on-raspberry-pi/)?

So the login UI appears but admin / admin is not working? Is that an accurate description?

You can use `grafana-cli` to reset the admin password. [Here is a guide:](https://grafana.com/docs/grafana/latest/administration/cli/#reset-admin-password)
