EG4 Web API and Home Assistant

There are a few projects out there that connect directly with your inverter to get some data.  Someone over on DIYSolarForums asked if there was an API for the web.  There's only a B2B API at the moment, so I decided to write a Python wrapper for people to be able to query their inverter and battery data vis the web (Monitor.eg4...).

Then I decided to use that to try to create my first Home Assistant integration/Custom Component.  Note that I only have access to a single 12000XP so YMMV!

....

ok so the first attempt at custom integration has started...Feel free to try it out

https://github.com/twistedroutes/eg4_inverter_ha
using the api from
https://github.com/twistedroutes/eg4_inverter_api

Done:

• Inverter Runtume
• Inverter Energy
• Inverter Battery Data
• Inverter Battery Unit Data
• Inverter Read Func, Hold and Bit Parameters
• Inverter Write Hold Parameters

ToDo:

• Inverter Write Func and Bit Parameters
• Obtain Value Limits for write functions
• Build some example dashboards
• Add Home Assistant ability to change values
• I've got to write up some tests
• validate the data scaling (e.g. where EG4 provide 5100 to represent 51.00 V),
• create a few more virtual sensors (a sensor made from other sensors data, like capacity in KWh = voltage and capacity in amp-hours).
• Then add some switches and inputs to change data
• Then add an example dashboard (though this data can already be used in the Energy dashboard)
• This can be loaded into your .homeassistant/custom_components (or wherever your custom_components folder is).
• I dunno... whatever I figure I need at the time.
