6 months ago I think it is important to create some visualisation (for example) using telegraf/influxdb/grafana. To have a better overview what happened und to compare it with other days. Here are some dashboard-images of my current setup. I have currently 2 PV-Modules (PV-Module 3 & 4) directly attached to my Hoymiles Inverter and 4 PV-Modules attached to the Solarflow-Hub. I'm not using the Inverter to limit the Energy. I'm only limiting on the Solarflow-Hub (using solarflow-control) by reading Energy-Levels from smart power-sockets (flashed with Tasmota-Firmware) via mqtt.
The first image is from yesterday, where it was quite cloudy (nearly no sun). Only 6 percent SOC for the complete day (I have currently ~4 kw/h solarflow batteries installed). The battery starts to work (deliver energy) at around 17:00 (green) for 1 hour. The second image is from today (lot better).
I'm normally in the situation where the battery is never full (because less sunshine). So the battery will start to deliver when the sun is set. As soon as we will have more sun, and my SOC is reaching 100% before sunset, I will send some newer images. But so far I'm very pleased. The setup is working as expected for nearly 3 weeks now.

Hi @reinhard-brandstaedter,
its me again, with another question. Today, I faced the situation, that I have full sunshine and should get (and got right before the battery was full) around 500W from the solar panels (almost same weather as yesterday, so I can take the values from there). My battery was empty a few days ago, so charge-through was kicking in and did its job. It finished around 12:30 mid day today. Since then, my solar production did drop severely (one panel seems to be sleeping at all and the other one only produces 50ish watts. My home consumption was around 350W but the SF-output value was only set by your app to 30W as it reported such low solar production - although as mentioned I had full sunshine... I "fixed" it by connecting one of my 3 panels to the inverter directly again. But its actually a mystery to me what happened.
As I will use the hub2000 when it arrives and I wanted to test how the app works with only hub connected panels, I connected 2 of my current panels by using a Y-adapter into PV-input 1 of the hub and the last panel onto PV-input 2. This is ok as I have 2 Panels which in current season barely exceed 400W together which is no problem for the hub - and it was anyway only a test. I was using this setup for almost a week, so its not a setup-issue I'd say.
Is this a problem of the application that it kinda needs a direct connected panel somehow? Do you need any more information from my end to "debug" this?
