I agree. Now, it looks cute, I must say, but I think it's mostly useless. The industry now seems to be in the phase of cargo-culting measurements - all going "we have to put EVERYTHING on graphs!" without stopping for a moment and asking "what am I planning to do with this data?".

Graphs, tables and other ways of representing data should be there to help you make decisions, not to just look cool. So yeah, go ahead and collect toilet flushing data; maybe you'll find something interesting there. But the way it's presented now, most of that data is useless. The number of toilet flushes since today morning doesn't really tell you anything without context. Even "x% above/below average of last week", or better, a sparkline of previous week's worth of data would give you some baseline that could let you interpret that flush count in a useful way.

Basically, my gripe with people in IoT and Quantified Self is that they totally cargo-cult graphs and dashboards.
