Reset Yield total and Store yield today ?! about ahoy

It is possible to reset Yield total ? ---> The value ist stored in the inverter. Can not be reset until today

It is possible to make a Little history for yield Today Which Save the Last Month?

You need an MQTT server. A database. And something to show that off nicely.

For this I use a RaspberryPI on which ioBroker runs with MQTT, as the database influxDB, and I display this graphically in Grafan. In Grafana you can then display everything possible. Day/Week/Year/ Last 5 minutes/... and much more

I think like @thinklerde mentioned. You should do this kind of post processing in an environmet where you have resources to store a lot of data.
My sight to the ESP module is more like a bridge between inverter and your home automatisation.

@eeprom23, in theory we could store the past 31 daily yields on the ESP (either in memory or on the flash / eeprom). Currently the code does not run stable enought for all of us to really make use of such a feature.

@lumapu, would that be something we would include as a feature in the future, i.e. write the daily yield into a circular buffer / round robin db on the flash mem ? I expect some degradation of the flash mem if we write to the same locations in eeprom daily. We would also need some kind of wear leveling.

@NDS234 you are right, values in the inverter can not (yet) be changed from the DTU.
I have seen something in the Hoymiles code that resets the daily yield UsartNrf_ClearMI_DailyEnergy() and some history UsartNrf_ClearMIReal_HistoryEnergy() as well as the current status and command UsartNrf_ClearNetStatusAndCmd() or the version action and state UsartNrf_ClearVersionActionState(). But they all seem to reset the counters in the DTUs own memory only. Maybe some of the download / update methods may be used in the far future if someone feels daring and adventureous ?

@eeprom23 das YieldTotal kann m.W. nicht überschrieben werden.
Die DTU-Pro überschreibt nur ihr eigenes YieldDaily auf dem SPIFFS der DTU, nicht das im WR!
Daher bitte das Issue als nicht lösbar schließen. Danke.
