Hey guys!
I got a question I can’t figure out. I am trying to create a template sensor to help me judge whether or not it is useful to open the windows to lower the humidity. I can calculate the respective absolute humidity just fine but I am having trouble calculating the offset … it will just not calculate anything but instead turn the sensor to „unavailable“.
variables:
inside:
{{ ((e ** ((17.67 * (states('sensor.tuyathsensor2_temperature')|float)) /
(243.5 + (states('sensor.tuyathsensor2_temperature')|float)) ) * 6.112 *
(states('sensor.tuyathsensor2_humidity')|float) * 2.1674 ) / (273.15 +
(states('sensor.tuyathsensor2_temperature')|float))) | round(1) }}
outside:
{{ ((e ** ((17.67 * (state_attr('weather.forecast_home',
'temperature')|float)) / (243.5 + (state_attr('weather.forecast_home',
'temperature')|float)) ) * 6.112 * (state_attr('weather.forecast_home',
'humidity')|float) * 2.1674 ) / (273.15 +
(state_attr('weather.forecast_home', 'temperature')|float))) | round(1) }}
offset: {{ 'inside' - 'outside' }}
state: {% if 'inside' < 'outside' %} Lüften
{% else %} Schliessen
{% endif %}
Also, is there a way to show this offset value as some kind of a gauge?
