Hi, yes you can. We have released the Javascript source code of the Kindle App as open source, which you can get from here…
https://github.com/digitalyacht/ikommunicate/blob/master/Kindle_App_Example.zip
If you create a sub-folder in the Signalk folder on your Openplotter system and then unzip the files in to this sub-folder, renaming the iKommunicate-API-Kindle.html file to index.html, then when you go to 10.10.10.1:3000/signalk/kindle it should run the Kindle app. You might have to fiddle around with the URL the App tries to use to get the Signal K data, but it should be doable even by a non-developer (which also describes me).
I am sure there are developers on the OpenPlotter project that could help.
