Getting the most out of this great add-on

[arohl]

I have to say that I have been overwhelmed by all the data provided by this add-on. What I am looking for is a guide showing what the key values mean and how to use/monitor within homeassistant. I don't think such a thing exists but I am happy to write one provided I can can the help I need to explain some of the things. One of the first things I would like to do is create a visualisation like the one in the official app i.e.

I think I have figured out where to get the battery data from (create two template sensors from battery_1_charge_discharge_power) but have a number of further questions. I don't think anyone would disagree that a document showing ways to use the integration in homeassistant is a good idea, so my question is what is the best way to ask questions of the community on my journey? The answer of course could be this issue ;-)

It would be nice to have a guide. [Pedro_Trancoso] has made a description on how he made a app-like active power diagram. I think the template sensors he made could be used to make your visualization. the thread is about the 'Solar inverter huawei 2000L' Integration but there is a lot to learn for a fusion solar user. https://community.home-assistant.io/t/integration-solar-inverter-huawei-2000l/132350/2110

Great link! I'll do some exploring...

Feel free to create PR's that ad more documentation, or with useful links, ...

I've already got it on my list of things to do to generate some code that allows us to replicate the FusionSolar graphs. I've spent a lot of time making some notes, but haven't really gotten it to the point where I'm happy to start writing code :). I will see if my notes are worth sharing or just mindless ramblings when I get home later.

I have made some headway. The integration with the energy panel is working for my solar/battery system. It wasn't totally obvious though. Do others also use:

• Grid consumption = Meter-1 - Reverse active energy
• Return to grid = Meter-1 - Active energy (forward active energy)
• Solar production = Home - Total Current Day Energy
• Battery energy in = Battery-1 - Charging capacity
• Battery energy out = Battery-1 - Discharging capacity

One reason it wasn't obvious is that I have now figured out that the battery charging happens directly from the solar panel and bypasses the inverter (which is why no sensors from the inverter are included above) - which is efficient but I don't think all systems do this.

If others use these values, please let me know and I will write up.

I haven't added Consumed from PV yet as I can't see why that's useful and am thinking of adding in grid consumption and production

[aretokas]

Seems promising. This is yesterday with those sensors in use. If only "Net Returned To Grid" was a useful indicator given that people rarely get a 1:1 credit.

👍 Looks good! Feel free to create a PR to improve the docs with a description on how you have configured everything

[arohl]

Should this be added to the README.md or create a seperate doc?

[tijsverkoyen]

README.md is goof. If needed I will split it later.

As there is no update on this I will close this issue.
