### Jinja-Template zur Taupunktberechnung:
------------------------------------------
{% set t = float(states('sensor.dht_aussen_temperature')) %}
{% set h = float(states('sensor.dht_aussen_humidity')) %}
{% if t < 0 %}
  {% set a = 7.6 %}
  {% set b = 240.7 %}
{% else %}
  {% set a = 7.5 %}
  {% set b = 237.3 %}
{% endif %}
{% set sdd = 6.1078 * 10**((a*t)/(b+t)) %}
{% set dd = sdd * (h/100) %}
{% set v = log(dd/6.1078, 10) %}
{% set tt = (b*v) / (a-v) %}
{{ float(tt) | round(1) }}

### Jinja-Template zum Vergleich der Taupunkte:
-----------------------------------------------
{{ float(states('sensor.taupunkt_innen')) - float(states('sensor.taupunkt_aussen')) > 5 }}

### ESPHome-Konfiguration des Außensensors mit blinkender LED:
--------------------------------------------------------------
sensor:
  - platform: dht
    pin: 28
    temperature:
      name: temperature
    humidity:
      name: humidity
    model: DHT22
    update_interval: 30s

output:
  - platform: gpio
    pin: 32
    id: led

interval:
  - interval: 2000ms
    then:
      - output.turn_on: led
      - delay: 100ms
      - output.turn_off: led
      
### ESPHome-Konfiguration des Kellersensors mit Relais-Platine an GPIO-Pin 27 und virtuellem Lüfter-Automatik-Schalter (Status über LED):
-----------------------------------------------------------------------------------------------------------------------------------------
sensor:
  - platform: dht
    pin: 28
    temperature:
      name: temperature
    humidity:
      name: humidity
    model: DHT22
    update_interval: 30s

switch:
  - platform: gpio
    pin: 27
    name: fan
    restore_mode: ALWAYS_OFF
  - platform: gpio
    pin: 32
    name: automode
    restore_mode: ALWAYS_ON
