This component simplifies the integration of a APsystems inverter:

• creates up to individuals sensors for easy display or use in automations
• collects produced, consumed and exported 'instantaneous powers' (W) and 'total energies' (KWH) every 5 minutes. There is also a sensor for daily total energy and max power produced.
• extract data from apsystemsema.com web portal instead of hack the ECU connection
• supports any kind of ASsystems inverter or ECU
• if enabled, pauses from sunset to sunrise (basically when there no sun)
• have a cache system to avoid individual sensors request the same data to apsystemsema.com. It is a great feature for I/O (HTTP) performance.
• there is a date sensor to identify exactly date/time refers each sensor data

The URL called are https://apsystemsema.com/ema/ajax/getReportApiAjax/getPowerOnCurrentDayAjax, https://www.apsystemsema.com/ema/ajax/getReportApiAjax/getPowerWithAllParameterOnCurrentDayAjax and https://www.apsystemsema.com/ema/ajax/getReportApiAjax/findMeterEcuEveryYearEnergyInLifeTime It is only called from sunset to sunrise and the sensor going offline at night

Use HACS to point to this github URL: https://github.com/skelgaard/homeassistant-apsystems

Use your apsystemsema.com to configure the addon.

1 - set "Allow visitors to access to this system" and get the authid from here

2 - your systemId is found at apsystemsema.com. click on the modules or report->system data->ecudata and the systemid is in the dropdown

If you see no data an error in the logs, make sure you can login on https://apsystemsema.com and don't see a captcha, if you do, solve the captcha and the data should start to come in again.

To get debug info in the logs do

logger:
  default: info
  logs:
    custom_components.apsystems_api: debug

and then grep the log for output

grep apsystem home-assistant.log

here is the two commands to run, todo a request test if it works

GET https://www.apsystemsema.com/ema/intoDemoUser.action?id=apsystemsem_authid

POST https://www.apsystemsema.com/ema/ajax/getReportApiAjax/getPowerOnCurrentDayAjax

queryDate=20250901&selectedValue=apsystemsema_ecu_id&systemId=apsystemsema_system_id

Thanx to the author bgbraga(https://github.com/bgbraga/) for his work, but as he has left this is in a none working stage, i have fixed the problems
