Now that I can see daily usage within 24-48 hours, you've natively gamified the experience, so now I want MORE info. I'd love to be able to add tags or custom notes to individual days on the graph so I can specify on unusual days if it was a super hot day so aircon was used far more than normal, or on holiday (away) or at home with TV on more than usual (e.g sick), or working from home etc.
This would allow me to try to spot patterns in usage so I know which of these reasons might be acceptable or which days we could have done more to save energy.
This is as much about costs as about saving household energy in general.
