Would love to help extend this #16

I have 2 x GW5048-EM Hybrid inverters. One with a battery, the other without (for now). I would like to try and assist in getting better/more data about battery states etc. I wrote a small API to power an Android app in my house, and got some insight into how (badly) the data is displayed from the SEMS Portal.

TimSoethout commented 4 years ago

Please see the experimental issue and branch for multiple inverters: #10

A starting point to extract better data is to look at the JSON the SEMS API supplies, but you might already be doing this.

And of course pull requests are welcome. Also discussions on how to make the component better/ more official-hass-like are nice. :)

I will take a look into the "multiple inverters" branch. Are you basing it around 2 inverters in 1 plant, or 2 plants? Ive been down the 2 inverters in 1 plant path, and there are massive issues with how the data is shown/calculated, especially if there are battery/batteries in the mix.

Up to this point, Goodwe have seemed unwilling to help, with their only suggestion being "put the inverters in different plants".

So I wrote my own basic API (to feed my Android app) to help avoid some of their data issues.

What I am mostly interested in, is the 'power flow' data. Showing values for load, pv, battery, grid and the direction (buying/selling/generating etc) of the power.

My ultimate goal (although I currently have no idea how to do this) would be to make a custom Lovelace card that shows data flow.

Here are some screenshots of the Android app I wrote, to show in the middle of the house so the kids can easily understand what's going on. https://imgur.com/a/UfKvGvU

The lines between the solar/load/battery/grid are all animated in the direction of flow at any given time.

We use "_PowerStationURL = 'https://www.semsportal.com/api/v1/PowerStation/GetMonitorDetailByPowerstationId'" for each power station, so I think this is per inverter, independent of plants.

Looks really cool. I think you should be able to do something like this using HTML/CSS in lovelace, although I don't have any specific experience with this.

My system is currently set up as 2 'plants' with 1 inverter in each. This is still not ideal, as the SEMS Portal makes a mess of it, but less than if you have 2 inverters in 1 plant.

Sadly, I am not that good with python. In the 'powerflow' section, the pvStatus/gridStatus/loadStatus/betteryStatus (yes, bettery..) are returned as 1 or -1. In my PHP code I make it return 'generating' or 'selling' or 'idle' etc, based on that, but I am unsure how to do that in python.

TimSoethout commented 4 years ago

I think you can visualize that better with home assistant templates. You include some logic to show -1 as "off" and +1 as "generating". See the home assistant documentation for more info. I think these templates are also what you use in a lovelace card.

Sorry, you're right.. I was trying to use the template in configuration.yaml to set the value.. perhaps I was doing it wrong.. will try to read some more documentation

wishie commented 4 years ago

Ok, I am back on deck and have a few hours to look into multiple inverters. I should also mention, there is now a GoodWe integration that uses UDP directly to the inverter (avoiding SEMSPortal) but not all of the same data is available. I will likely only need the SEMS integration for a few unavailable datapoints via UDP.

TimSoethout commented 3 years ago

Nice. I would also rather use the UDP plugin, but my inverter model does not seem to be supported yet.

I'll close this issue for now. Feel free to reopen or open a new one. :)
