+Vous devez avoir choisi la fonctionnalité ```Avec détection des ouvertures``` dans la première page pour arriver sur cette page.
+La détecttion des ouvertures peut se faire de 2 manières:
+1. soit avec un capteur placé sur l'ouverture (mode capteur),
+2. soit en détectant une chute brutale de température (mode auto)

-![image](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/config-window.png?raw=true)
+### Le mode capteur
+En mode capteur, vous devez renseigner les informations suivantes:

-Donnez les attributs suivants :
 1. un identifiant d'entité d'un **capteur de fenêtre/porte**. Cela devrait être un binary_sensor ou un input_boolean. L'état de l'entité doit être 'on' lorsque la fenêtre est ouverte ou 'off' lorsqu'elle est fermée
 2. un **délai en secondes** avant tout changement. Cela permet d'ouvrir rapidement une fenêtre sans arrêter le chauffage.

-Et c'est tout ! votre thermostat s'éteindra lorsque les fenêtres seront ouvertes et se rallumera lorsqu'il sera fermé après le délai.
+
+### Le mode auto
+En mode auto, la configuration est la suivante:
+![image](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/config-window-auto.png?raw=true)
+
+1. un seuil de détection en degré par minute. Lorsque la température chute au delà de ce seuil, le thermostat s'éteindra. Plus cette valeur est faible et plus la détection sera rapide (en contre-partie d'un risque de faux positif),
+2. un seuil de fin de détection en degré par minute. Lorsque la chute de température repassera au-dessus cette valeur, le thermostat se remettra dans le mode précédent (mode et preset),
+3. une durée maximale de détection. Au delà de cette durée, le thermostat se remettra dans son mode et preset précédent même si la température continue de chuter.
+
+Pour régler les seuils il est conseillé de commencer avec les valeurs de référence et d'ajuster les seuils de détection. Quelques essais m'ont donné les valeurs suivantes (pour un bureau):
+- seuil de détection : 0,05 °C/min
+- seuil de non détection: 0 °C/min
+- durée max : 60 min.
+
+Un nouveau capteur "slope" a été ajouté pour tous les thermostats. Il donne la pente de la courbe de température en °C/min (ou °K/min). Cette pente est lissée et filtrée pour éviter les valeurs abérrantes des thermomètres qui viendraient pertuber la mesure.
+![image](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/temperature-slope.png?raw=true)

+- Add sensors to see the internal states of the thermostat

+You must have chosen the ```With opening detection``` feature on the first page to arrive on this page.
+The detection of openings can be done in 2 ways:
+1. either with a sensor placed on the opening (sensor mode),
+2. either by detecting a sudden drop in temperature (auto mode)

-Give the following attributes:
-1. an entity id of a **window/door sensor**. This should be a binary_sensor or a input_boolean. The state of the entity should be 'on' when the window is open or 'off' when closed
-2. a **delay in seconds** before any change. This allow to quickly open a window without stopping the heater.

-    1. If you want to use **several door/windows sensors** to automatize your thermostat, just create a group with the regular behavior (https://www.home-assistant.io/integrations/binary_sensor.group/)
-    2. If you don't have any window/door sensor in your room, just leave the sensor entity id empty
+### Auto mode
+In auto mode, the configuration is as follows:
+![image](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/config-window-auto.png?raw=true)

+1. a detection threshold in degrees per minute. When the temperature drops below this threshold, the thermostat will turn off. The lower this value, the faster the detection will be (in return for a risk of false positives),
+2. an end of detection threshold in degrees per minute. When the temperature drop goes above this value, the thermostat will go back to the previous mode (mode and preset),
+3. maximum detection time. Beyond this time, the thermostat will return to its previous mode and preset even if the temperature continues to drop.
+
+To set the thresholds it is advisable to start with the reference values and adjust the detection thresholds. A few tries gave me the following values (for a desktop):
+- detection threshold: 0.05°C/min
+- non-detection threshold: 0 °C/min
+- maximum duration: 60 min.
+
+A new "slope" sensor has been added for all thermostats. It gives the slope of the temperature curve in °C/min (or °K/min). This slope is smoothed and filtered to avoid aberrant values from the thermometers which would interfere with the measurement.
+![image](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/temperature-slope.png?raw=true)
+
+To properly adjust it is advisable to display on the same historical graph the temperature curve and the slope of the curve (the "slope"):

+With the thermostat are available sensors that allow you to view the alerts and the internal status of the thermostat. They are available in the entities of the device associated with the thermostat:
+
+![image](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/thermostat-sensors.png?raw=true)
+
+In order, there are:
+1. the main climate thermostat command entity,
+2. the energy consumed by the thermostat (value which continuously increases),
+3. the time of receipt of the last outside temperature,
+4. the time of receipt of the last indoor temperature,
+5. the average power of the device over the cycle (for TPIs only),
+6. the time spent in the off state in the cycle (TPI only),
+7. the time spent in the on state in the cycle (TPI only),
+8. load shedding status,
+9. cycle power percentage (TPI only),
+10. presence status (if presence management is configured),
+11. security status,
+12. opening status (if opening management is configured),
+13. motion status (if motion management is configured)
+
+To color the sensors, add these lines and customize them as needed, in your configuration.yaml:
+
+```

+  themes:
+    versatile_thermostat_theme:
+      state-binary_sensor-safety-on-color: "#FF0B0B"
