Homeassistant solar battery charge prediction

Offline Homeassistant-solar-forecast-and-battery-state-forecast

Homeassistant solar battery charge prediction with display card. Works plug and play with the modbus sungrow integration for HA (https://github.com/mkaiser/Sungrow-SHx-Inverter-Modbus-Home-Assistant)

(first row is only shown when there is no production/ second and third row is shown when there is production.

Features

all features are tested and only approximate real circumstances!

• fully offline!
• predict battery state at evening after charging
• predict battery state at morning after decharging
• predict battery charging time
• predict minimum charge needed to get over night
• predict time left of solar
• predict start of charging
• example lovelace card (mushroom required)

ToDo

any contributions to improve the code are appreciated!

• compleate english translation (most entitys have english description in code)
• improve konfiguration
• improve accuracy
• sometimes the prediction fails by calculating negative percentages because of insufficient solar. this should be limited to realistic values (0-100%)
• use local weather data to improve prediction

Installation

please contribute ANY upgrades to the card or algorythm thia helps everybody!

1. copy all files oft the battery-predict.yaml into your custom yaml integrations folder
2. make changes for your individual setup (set entity ids battery size, avg consumtion...)
3. copy the card as a manual yaml config into lovelace. !mushroom required!
4. edit the current production of solar entity in the conditional cards
