Hi,
is there a way to calculate Sun Energy with a Helper?
I build that in a template, but it has a few Problems, if some counter is NaN or just resets to much
Any ideas what i can do, that i just get a number there and its just growing up and not starting from 0 again or double the number after a yaml restart or so?
- sensor:
- name: 'solarcalculation'
device_class: energy
unit_of_measurement: kWh
state_class: total
state: >
{% if is_number(states('sensor.solarcalculation')) and is_number(states('sensor.hauseinspeisung_heute')) and is_number(states('sensor.akku_geladen_heute')) and is_number(states('sensor.akku_entnommen_heute')) %}
{% set new_state = (states('sensor.hauseinspeisung_heute')|float + states('sensor.akku_geladen_heute')|float) - states('sensor.akku_entnommen_heute')|float %}
{% if new_state >= states('sensor.solarcalculation')|float %}
{{ new_state }}
{% else %}
{{ states('sensor.solarcalculation')|float }}
{% endif %}
{% else %}
0
{% endif %}
I have two Sensor that puts sunenergy in, and one grabbing it out, so i need to calculate two together and the from the sum i need to subtract the “akku_entnommen_heute”.
But if one is NaN, it goes to 0, if i dont write 0 in else, i get NaN also in solarcalculation, which is bad. It is okay if some of the sensors is NaN, but i need a growing number out of the solarcalculation
