shal thank you for the invitation, I'm newbie in WEB development (to be precise, I'm not a WEB developer at all, as I work with Qt/QML/C++ tech), but I have some community (small yet) which seems emerging, so hopefully we could contribute one day.
About Grafana, it looks nice but might be not exact instrument I need.
My task for now is a thermostat, so I need a dashboard with all the widgets I might need, graphs included.
Working prototype is here, but it's just ugly Android app with proprietary server behind which imposes a lot of restrictions, so it's what we would like to avoid.
Still, it has graphs:
The graph widget is just a basic HTML/JS so maybe we could adopt it for MQTT Tiles, too:
I bet you have better idea how to do graphs, though 🙂
