Another possible consideration is the graphs. The graphs produced and saved by the graph module are now accessible using the graph name and readkey.
I just took a peek at the dashboard module and it would be a trivial change to make the dashboard/list.json api available via the read apikey.
I wish we did have a more full featured android app. Or at least set up emoncms as a “Progressive Web App” (I hope I coined the right terminology there!)
