You can only put a dashboard on a TV if the streaming service you use will allow you to log in to Looker. This isn't possible with a Raspberry Pi or Airtame since they only take a web address and don't let you navigate or use any input.

The options here are public look or SSO embed.

As of Looker version 6.24, content can be made public but restricted by IP address - so a public look could be made accessible to the Raspberry Pi's IP address and prohibited for all others.

Looker doesn't have the notion of public URL for dashboards, and probably never will since you can achieve the same using SSO embed. Just have the raspberry Pi web server generate an SSO Url with a particular embed user configuration and you're done.

Presumably, the Looker content they want to display on the TV screen will need to be refreshed periodically (dashboard refresh?). It's recommended that the Raspberry Pi device generate a new SSO URl periodically as well, perhaps daily.

I’m a bit late here, but sharing in case folks still run into this problem… 

 

Fugo has a tidy solution for this… you don’t need to make any dashboards public or log in from the display device. You can either use the dedicated integration to copy & paste the dashboard URL & secret key from your Looker account into Fugo app (there’s a simple run down here.)

Alternatively, you can use the TV dashboard feature; which works by recording steps & log-in credentials securely in AWS, then reproducing them to get to your dashboard or Look, take a snapshot, and send it to your screens. It’s a secure & quite easy workaround to loading dashboards directly onto TV screens (run down here.) And since you’re displaying just a screenshot of the data, you don’t need a pro-grade player - even a Raspberry Pi can handle the job. 

 

Hope that helps!
