Can't connect to Energy Manager flex

My setup: Home Assistant 2023.4.6 Supervisor 2023.04.1 Operating System 10.1 Frontend 20230411.1 - latest on Proxmox 7.4-3 server.

I have a fronius Symo 3.0.3-M, a BMW flex Battery and the Solarwatt Energy manager flex (there is paper-ui with openHAB on it?!). The manager works, I can access it via http (and password); HAS and Solarsystem are in same IP subnet.

After installing this integration using HACS, I try to add the integration. After I enter the device IP in the host field, I got "Unkown error occured".

This is the log:

AND: I found a JSON link for this Solarwatt Energy Manager FLEX where all objects and data can be found! http://local-ip/rest/items The outcome of this call is a full list of data and individual likes for items. An item link looks like:

{"link":"http://192.168.x.xx/rest/items/solarwattBattery_batteryflex_BatteryFlex_0BFFAE_houseChannelGroup_housePowerConsumption","state":"-0.5 W","stateDescription":{"pattern":"%.2f %unit%","readOnly":true,"options":[]},"editable":false,"type":"Number:Power","name":"solarwattBattery_batteryflex_BatteryFlex_0BFFAE_houseChannelGroup_housePowerConsumption","label":"House Power Consumption","tags":[],"groupNames":[]}

I think you have the newer energy manager flex, which isn't supported by this integration. The data interfaces are completely different.

I think so, too.

While -logically - I understand what to do, I don't know how. I have no experience in reading a JASON to an array, do related string operations, add Home assistant like attributes and parse everything as sensors and entities to Home Assistant. I've never done this and I never found a good documentation on how to. This is my challange:

Github
Python?
find a good editor
I can do VBscript, PHP, Mysql, html (of course), Turbo Pascal, BasicV7, Cobol, a bit c++, AutoIT stuff and everything a scripting guy might know. But this world here - with Git, Python and all the YAML/Jason formats - I never found a way into it. Maybe I'm just too old in the meantime...

So I hoped, when I share the details here, that you might be able to integrate this easily to your code. I'm sorry, to hear that this is completely different.

The editor of choice is Visual Studio Code. Python is quite easy to learn if you know programming already. Essentially you just need to use http to get JSON data from the energy manager flex, then parse the data and send it to home assistant.

You can try to copy this project and try to adapt it to the new energy manager flex.

This integration is basically split into two projects.

https://github.com/Mas2112/solarwatt-energymanager-py

The above project makes the http request and parses the JSON into an object.

The home assistant project makes the data available to home assistant.

I would just copy the code from the two projects into one project and just try to adapt it.

Here is an article on how to create a custom component.

Thanks for the links. I read a bit deeper through your code yesterday. I'll try my first steps... :-)

Thank you again.
