This repository provides a set of blueprints for Home Assistant to generate an Energy Management System (EMS) for your home. The focus today is on Charging electrical vehicles including a Surplus charging capabilities for those who want to leverage their Solar energy at home. The scripts works independently but needs to be set up in a way that helper entities are used.
This is the default script you will need to use if you start with your automation. This script makes sure to adopt the different settings based on a Charging Type - a helper entity - that contains the following Options (Default, Trip, Surplus, Morning-Min and Stop).
If Surplus is activate this script runs every 5 seconds to set the correct current value on the charger based on a potential power mean. To create a mean power sensor use the ha-average Extension Ideally you set a 5 min window on it to smooth peaks for the charger.
Example configuration.yaml entry for the average sensor
sensor:
- platform: average
name: "[EMS] - [Car] - Potential Power mean
unique_id: ems_car_potential_power_mean
entities:
- sensor.ems_car_potential_power_now
duration: 00:05:00
If you are using Surplus charging by default this script will make sure that you have at least a certain battery level in the morning when you want to leave.
This is only useful for go-e charger owners that want to use the ECO mode. It publishes the available power over mqtt to the go-e charger. For this the home-assistant-goecharger-mqtt Extension is needed. As the charger is not really taking those values into account it's a nice to have but not necessary.
Based on entries within a selectable calendar in Home assistant this script makes sure that your battery reaches a configurable state before you have to leave. You can leverage any calendar e.g. the Google Calendar Integration.
