can you try again - i fixed a couple things!
My fork should appear in the HACS store along side Nathan's original.
i just downloaded it fine from the hacs store.

It Worked! Thank you so much for your hard efforts! It's great to finally have real data without relying on the cloud.

I've connected my Evo 10 with a LAN cable (for those of you who are interested).

Thank you again!

no problem.
if you do see bugs, register them on github and i'll endeavour to work on them

Checks solar forecast tomorrow - works out a reasonable Max SOC at 7pm and writes it to the register.

Thank you Adam, your post inspired me to add two more automations.

Each day at 05:30 it will discharge if the current predicted solar output is above 12 kWh (I can adjust this later once I get used to it) and then it will force discharge until 06:30, when another automation switches it to Feed-in.

This is so I can mop up the solar above my 3.9kW export limit, as I have 6.16kWp and clipping occurs.
And it shouldn't work if the day is dull, so I keep my battery SoC higher.

Sounds good! Are you doing it through HA ui?

Yeah via HA, and built in solar forecast tool

That’s brilliant man!!

I will see in the morning if it works, but on paper it does at least.
Forecast is for almost 20kWh, and I set the threshold to work above 12kWh.

I will be back crying if it doesn't work

I signed up for solcast. It’s free for single residential owners. I may have to compare it to the stock solar forecast tool!

Much more accurate from what I've seen. In particular it also gives figures for the 90% percentile and 10% percentile which gives a good grasp of the variability in the forecast.

The built in HA solar forecast said 9.3kWh
Solcast said for today 13.4kWh
Inverter reported 12.9kWh

I will need more long term data, but have to see how it pans out. The built in tool doesn't seem that accurate for today, but it's only 1 set of data points.

I have node red fill a csv file each day after sunset that has actual and predicted on it. I just can’t find it on my HA VM
