As @AjitKumar stated, if you want to create your own dashboard, rather than use the standard Dashboard, to show the status of multiple networks on one screen then you’ll need to use the API to obtain the information and create a webpage to display it.
Is there something you want to see that you can’t on the standard Meraki Dashboard?
With regards to the license, I believe the Meraki Dashboard starts providing a ‘yellow’ license warning when you are 90 days out from your expiry date by default.
