How to update the Solar saving value for a specific day?

Hi,

On a freshly installed Fox ESS v2 app I've set up a new TOU Tariff and in it a buy tarif. Sadly I've set up the value as currency instead of cents of the currency and ended up with a number 100x too large.

I didn't realise at that point in time that it was possible to update the Tariff (not very clear that you can select the dark grey numbers on a black background to modify them...) and deleted the tariff in question to recreate one with the right value. Sadly I'm now stuck with a couple of days with a "Solar Saving" value that is k100x what it should.

Is there a way for me to edit this two specific days?

If not, how can I reset the data completely? I would prefer to restart fresh and clean instead of carrying bad numbers in the interface forever.

Thanks for your help!

sadly there is no way to fix prior data issues; just set it correctly for correct data going forward.

You are better to track your solar savings via a spreadsheet.

You can see how much you export/import/self-use and if you are with a VPP (virtual power plant) track that too.
I made a spreadsheet to track ROI, to see how long it takes to pay off, and just tracking solar production etc.

I only add monthly figures into it, not too hard to make one if you are familiar with simple spreadsheet sums.
