I second this! I've been sending sensor data into the https://sensor.community cloud for over a year now, with dead simple setup and forget-about-it attitude since then. For the lazy there is also an option of spending ~50€ for a plug-and-play version [1]. Independently of that, you also get a grafana web GUI after registering your chip, e.g. [2]. On another note, I hope these databases from similar projects stay mergable or the projects even merge.
