Hybrid Inverter Settings & API Integration App

Job ID: 39645272

Budget: €18 – €36 EUR

We need an app that simplifies the settings for a Deye hybrid inverter and more important, has an API connection to Solarman PV and EPEX prices to load/unload batteries at specific times. Original app would be amazing but a complete preset in Home assistant could also work if it's that much easier.

App should visualize:

- Cheapest hour
- Most expensive hour (Nordpool integration?)
- Homewizard data from p1 meter (existing connection in Home assistant)
- State of charge graph battery
- weather and PV production forecast (Solcast or PVGIS)

Settings should be limited to:

- percentage of battery used for personal electricity use (and the rest for trading)
- maximum price where to load
- minumum price to unload
- max watt of trading

Ideally the app goes on a dedicated touch screen (ideas welcome)
