Questions for pr #27 'Clear "Daily Production" every night by set time' about inverter-connect

[jedie]

Yes, a good idea!
Also because i have the SUN600 and he is also offline at night...

One Problem: What's if the status is lost? e.g.: The computer was rebooted or the services restarts by some other reason.

So you can't just init with "no reset made today" and toggle this boolean flag. Because every restart will reset the daily production, too.

So we have to store the state on disk to avoid this. Maybe just the date of the last reset into e.g.: ~/.config/inverter-connect/lastreset

I implement the idea in #61

We will see tomorrow if it's work ;)

Hm. Doesn't work, today:

But the reset was made, today:

cat ~/.config/inverter-connect/daily_reset_state.txt 
2023-05-27

Hm...

The original firmware resets the "daily production" at the first connection with the central server. With this implementation, you lose production between the first sun and the time you connect home. Yesterday, I re-enabled communication with the internet for the inverter, and the inverter resets the day's production immediately after.

What do you think about a similar approach by running "Set-Time" once a day, just after the software was able to connect to the inverter for the first time?

Using the status file to ensure that "Set-Time" is only run once a day, even if the software has been restarted.

The result would be very similar to the original firmware when the inverter is connected to the internet. There will always be a small amount not reported. If the software runs continuously, the amount is very small probably under 5 minutes of harvested energy at the beginning of each day.

This is exactly how it's implemented, now ;) But doesn't work. Don't know why.
