Eric's Flash Counter Project

You may recall that some time ago I expressed doubts about the accuracy of my Wattson Meter and said that I thought I could build something a bit more accurate.
Project isn't finished yet but I have now built a device to count the flashes from my meter (each one of which represents 1Wh being imported) and log them into a web-based database.
Most forum members would probably find the full details rather boring but anyone who would like further information might like to take a look at this LINK.
I'll be updating that occasionally as I test how accurate the system is &/or add new facilities.

So far, 116 MSE viewers have looked at this page and 15 have followed through to see the fuller explanation.
That page has now been updated to include approximate cost of device (a shade over £20) and show an example of a programme for the microprocessor and a script for the webpage that files results.NE Derbyshire.4kWp S Facing 17.5deg slope (dormer roof).24kWh of Pylontech batteries with Lux controller BEV : Hyundai Ioniq50 -
Thanks - very interesting little project. Considering my monitor (that also counts pulses) cost around £100 and has a really unreliable SD card transfer to a website, I might have to give this a go if I ever get any time.
