Hello. I am a newby trying to get started. I have understood that there should be an option to add triggers to a sensor so it would be possible to determine when a sensor runs. However, I am unable to do that.
Would appreciate greatly a push to the right direction.
configuration.yaml:
sensor: !include sensors.yaml
sensors.yaml:
- platform: template
sensors:
night_charge_scheduler:
unique_id: carchargerids.00001
friendly_name: Night Charge Scheduler
value_template: >-
{# Variables read from Helpers -#}
{% set charge_time = states('input_number.CarCharge_time') | int -%}
{% set night_start = states('input_datetime.CarCharge_Night_Start') | truncate(3, False, '.', 0) | int -%}
{% set night_end = states('input_datetime.CarCharge_Night_End') | truncate(3, False, '.', 0) | int -%}
{# Setting price addition -#}
{% set a = {
"day_tariff": 0.0521,
"day_peak_tariff": 0.0802,
"weekend_peak_tariff": 0.0464,
"night_tariff": 0.0299,
"contract_price_addition": 0.0024
}
-%}
{# Gettting Nordpool prices-#}
{% if state_attr('sensor.nordpool_kwh_ee_eur_3_10_02', 'tomorrow')[23]| string == 'None' -%}
{% set prices = state_attr('sensor.nordpool_kwh_ee_eur_3_10_02', 'today') -%}
{% else -%}
{% set prices = state_attr('sensor.nordpool_kwh_ee_eur_3_10_02', 'today') +
state_attr('sensor.nordpool_kwh_ee_eur_3_10_02', 'tomorrow') -%}
{% endif -%}

{% for price in prices -%}
{% set x = loop.index0 -%}
{% if loop.index0 < 24 -%}
{% set hour = loop.index0 -%}
{% set day = now().weekday() -%}
{% elif loop.index0 >= 24 -%}
{% set hour = loop.index0 - 24 -%}
{% set day = now().weekday() + 1 -%}
{% endif -%}
{% if day < 5 and ((hour >= 7 and hour < 9)
or (hour >= 12 and hour < 16)
or (hour >= 20 and hour < 22))-%}
{% set final_prices.values = final_prices.values +

{% set final_prices.values = final_prices.values +

{% else -%}
{% set final_prices.values = final_prices.values +
[(price + a.night_tariff + a.contract_price_addition) | round(4) ] -%}
{% endif -%}
{% endfor -%}
{#{ final_prices.values }-#}
{# making a vector of prices/times during "night charge" time window i.e. from night_start to

{% set night_charge_prices = namespace(values = [], time = []) -%}
{% for price in final_prices.values -%}
{% if (loop.index0 >= night_start) and (loop.index0 < (night_end + 24)) -%}
{% set night_charge_prices.values = night_charge_prices.values + [price] -%}
{% set night_charge_prices.time = night_charge_prices.time + [loop.index0 % 24]-%}
{% endif -%}
{% endfor -%}
{# during "night charging time" turn on only at cheapest hours -#}
{#{ 'need to turn on the charger (at hour, price)' }-#}

{{ night_charge_prices.time[loop.index0], night_charge_prices.values[loop.index0] }}
{% endif -%}
{% endfor -%}
Question1: where do I add the trigger and how? I do not seem to be able to - get an errorā¦
Question2: currently I am getting an array as an output that looks crappy (example:
(4, 0.1703) (5, 0.1703) (6, 0.1233) (7, 0.1773)
How can I access these values or assign these as attributes?
Thanks!
