That is precisely why I posted in response to your question a few
days ago:

Get them to split the feed from the meter (via a Henley block) to
a separate consumer unit for the PV only. This means that you can
slip a monitor over the cable feeding only the main consumer
unit. Otherwise you cannot tell if you are consuming or exporting
until smart meters arrive.

The Inverter display tells you what you need to know. George wants a
device to switch stuff on/off as PV power is available.

The inverter only tells you what is being generated. George also
needs to know what is being consumed. Only if you know both can
you (or a box of electronics) decide if there is generation to
spare. If you have to spend anything significant to achieve this,
it is unlikely to be able to pay for itself.
