I like the product and can see a couple of nice uses for it. For instance I have a grafana dashboard to track my solar setup. Home assistant stuff comes to mind. Maybe some contextual stuff like showing a 5pm ‘time to get off your ass’ message.
But I do agree that being able to do all that stuff without relying on someone else’s server would be more or less a requirement for me. I’d be fine with rendering html on some other machine if that’s the problem here.
