Custom Grafana Dashboard

I have a system where I am storing a lot of data in InfluxDB from many devices (an IoT project). I installed Grafana on one of the servers and can do some basic queries, but I am really looking for a custom dashboard where I can see the data all on one screen. I don't know a lot about the custom dashboards in Grafana, but ideally, I would want the same dashboard (look and feel with charts etc.) and just the ability to change one thing in a where clause to view different devices (there are thouands of devices, so I need a simple way to change it in there). I am open to ideas here mainly since I am not a grafana expert. This project is mainly on the grafana dashboard and ability to make it work, but you may need some idea on how InfluxDB works and how to query in there.
