Well that was easy enough to set up and get running. Works well.

Web page of the "Digitizer - AI on the edge - Watermeter" web page. A menu bar is across the top of the page underneath the branding title. Down the left hand side are some overview figures and system info at the bottom. On the right is a picture of our watermeter showing the digits "00000288".

And now I have enough data for a quick and simple NodeRed dashboard element...

Screenshot of a NodeRed dashboard. The following is shown:
Current reading (m³) - 1.917

| period | cubicMetres | cost |
+--------------+-------------+------+
| Today | 0.150 | 0.53 |
| Yesterday | 0.289 | 0.89 |
| This week | 0.974 | 3.09 |
| Last week | 0.943 | 3.15 |
| This month | 1.817 | 5.84 |
| Last month | 0.100 | 0.40 |
| This quarter | 1.917 | 6.24 |
| Last quarter | NULL | NULL |
| This year | 1.917 | 6.24 |
| Last year | NULL | NULL |
| All data | 1.917 | 6.24 |

And a line graph showing the last 12 hours of m³ consumed

Interesting that I am occasionally told to use #homeassistant rather than #nodered, but I honestly wouldn't have a clue where to even start programming this flow, for example, (just for our central heating and hot water) into HA - or even if it's possible.

Really complicated NodeRed flow with around 150 nodes and lots of lines connecting them all. There are two main sections - one for heating and one for hot water and there are also lots of smaller flows on the page

@NAB Some things just need to be in NodeRED. That is one of them.
