Maybe I’m the only person with this issue, but I thought I’d put it out there for discussion.
I can get data from my electricity supplier on my household consumption. It comes in 15 minute granularity, but with a day’s delay. I.e. I can never see my instantaneous consumption with this method.
I also have a ZigBee device attached to my electric meter (a Linky with a Lixee ZigBee device on the data port) that gives me data instantly (well, once per minute).
My problem comes from wanting to combine these two data sources.
- The day delay is annoying, but the supplier’s data is the gold standard, but it’s in 15 minute chunks.
- The ZigBee data can be more finely grained in time, but the physical layout of my property means the signal is very weak and occasionally I get no data at all for hours, or only one data point every hour or so. I have limited opportunity to improve the wireless link as the distance between the meter and the nearest place I can locate a repeater is fixed at about 15 m through two brick/concrete walls.
Is there a way I can combine these two sources of data without double counting the consumption?
