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)
If you like this repository please leave a star ⭐
All features are tested and only approximate real circumstances!
- fully offline!
- predict battery state in the evening after charging.
- predict battery state in the morning after discharging.
- predict battery charging time.
- predict the minimum charge needed to get overnight.
- predict the time left of solar.
- predict the start of charging.
- example Lovelace card (mushroom required).
Any contributions to improve the code are appreciated!
- Complete English translation (most entities have English descriptions in code)
- improve configuration
- 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
please contribute ANY upgrades to the card or algorithm this helps everybody!
- copy all files oft the
battery-predict.yamlinto your custom yaml integrations folder - make changes appropriate to your setup (set entity IDs, battery size, average consumption...)
- copy the card as a manual yaml config into Lovelace. !mushroom required!
- edit the current production of solar entity in the conditional cards
