I am trying to ajust a blueprint to charge my car on solar energy. When increasing or decreasing the charger current, i would like to wait for 1 minute. But I just can’t figure out how to do it. I am using variables for the calculation of the available current and available power. I have tried multiple solutions, but just can’t get it to work.
Can someone please help me and let me know how I can make a condition in the below blueprint that checks if the currentAvailableCharging > ChargerCurrent for 30 seconds, or waits/delays 30 seconds befor changing the ems_charger_current value?
The part I am trying to make work is:
- alias: Set Decreasing Charging current
if:
- condition: state
entity_id: !input ems_charger_status
state: 'charging'
for:
hours: 0
minutes: 2
seconds: 00
- condition: template
value_template: '{{ currentAvailableCharging < ChargerCurrent }}'
alias: Below Charging current
# for:
# hours: 0
# minutes: 1
# seconds: 00
then:
- action: number.set_value
metadata: {}
data:
value: '{{ ChargerCurrentMinOne }}'
target:
entity_id: !input ems_charger_current
alias: Set Decreasing Current
else: []
enabled: true
My updated blueprint starting from https://github.com/gsaurer/ha-ems is:
blueprint:
name: '[EMS] - [Car] - [Charging automation] - [Surplus] - Current-Start-Stop'
description: This script provides 3 different types of chaging (Default, Trip &
Surplus) and adopts the settings of the charger settings accordingly. In this
scenario the go-e Charger was used but the automation can be used for other chargers
asw well as it is generic.

on. It's the main switch for your EMS systm. If you don't have one create
a new one directly in the blueprint. Turning it off this will disable this
automation.

description: This defines which type of charging should be used - Potential

this entity create it directly in the blueprint and add it to your it to your
dashboard to select what charging type you want.

For that create a helper sensor that calculates the value based on your Perference.
It is recommended to leverage the ha-average integration and create an average
