I record my meter readings (both Grid and PV generation) weekly, but it doesn't tell me anything about how much is actually imported / exported during any particular day. Who knows? perhaps I am exporting (and could buy a PowerWall) or Importing (and could buy more PV panels ... or a Wind turbine?). We have single-phase supply.
I could, perhaps?, also have something to trigger usage by some device if PV is being exported. (Not sure what that might be though - Immersion seems like an easy candidate, but we also have Solar Hot water here, so not a particularly good "dump". Probably way too complicated, but dropping the temperature of Fridge / Freezer (we also have a Cold room) by a degree or so seems like a reasonable "dump" to me, but maybe a daft idea?
My PV Panels and inverter are a long way from the grid meter / supply / distribution panel (no idea, off hand, if there is a dedicated cable between the two - there might be, but there is also a sub-distribution board near the Solar PV / inverter (sorry, I'm not technical, no idea if those two things are likely to be related). Is that a problem?
PV installation, on roof, was part of a new-build extension, and there were definitely heavy duty cables from main distribution board to sub-board at that time.
I could do with some advice as to what sort of kit might help with monitoring. A quick Google has turned up

The OWL, at least, is a name I know, but feedback suggests very inaccurate (maybe only at low wattage generation). Maybe that is true of the others too (characteristic of Cable Clamp metering perhaps?)
All of them look like £100 would cover it, and having the benefit of the data is definitely worth that to me to then make an informed decision on further purchases, or make better use of my own generated PV ... or maybe something else?
Not sure this is the best place to ask, but trying to Google for UK forums where this is discussed didn't turn up anything that had a recent discussion.
