+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.

+## Modifier les paramètres de sécurité
+Ce service permet de modifier dynamiquement les paramètres de sécurité décrits ici [Configuration avancée](#configuration-avancée).
+Si le thermostat est en mode ``security`` les nouveaux paramètres sont appliqués immédiatement.
+
+Pour changer les paramètres de sécurité utilisez le code suivant :
+```
+service : thermostat_polyvalent.set_security

+# Notifications
+Les évènements marquant du thermostat sont notifiés par l'intermédiaire du bus de message.
+Les évènements notifiés sont les suivants: 
+
+- ``versatile_thermostat_security_event`` : un thermostat entre ou sort du preset ``security``
+- ``versatile_thermostat_power_event`` : un thermostat entre ou sort du preset ``power``
+- ``versatile_thermostat_temperature_event`` : une ou les deux mesures de température d'un thermostat n'ont pas été mis à jour depuis plus de `security_delay_min`` minutes
+- ``versatile_thermostat_hvac_mode_event`` : le thermostat est allumé ou éteint. Cet évènement est aussi diffusé au démarrage du thermostat
+- ``versatile_thermostat_preset_event`` : un nouveau preset est sélectionné sur le thermostat. Cet évènement est aussi diffusé au démarrage du thermostat
+
+Si vous avez bien suivi, lorsqu'un thermostat passe en mode sécurité, 3 évènements sont déclenchés :
+1. ``versatile_thermostat_temperature_event`` pour indiquer qu'un thermomètre ne répond plus,
+2. ``versatile_thermostat_preset_event`` pour indiquer le passage en preset ```security```,
+3. ``versatile_thermostat_hvac_mode_event`` pour indiquer l'extinction éventuelle du thermostat
+
+Chaque évènement porte les valeurs clés de l'évènement (températures, preset courant, puissance courante, ...) ainsi que les états du thermostat.
+
+Vous pouvez très facilement capter ses évènements dans une automatisation par exemple pour notifier les utilisateurs.

 This custom component for Home Assistant is an upgrade and is a complete rewrite of the component "Awesome thermostat" (see [Github](https://github.com/dadge/awesome_thermostat)) with addition of features.
 
+>![New](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/new-icon.png?raw=true) _*News*_
+> * **Release 3.1**: added detection of open windows/doors by temperature drop. This new function makes it possible to automatically stop a radiator when the temperature drops suddenly. See [Auto mode](#auto-mode)
+> * **Major release 3.0**: addition of thermostat equipment and associated sensors (binary and non-binary). Much closer to the Home Assistant philosophy, you now have direct access to the energy consumed by the radiator controlled by the thermostat and many other sensors that will be useful in your automations and dashboard.
+> * **release 2.3**: addition of the power and energy measurement of the radiator controlled by the thermostat.
+> * **release 2.2**: addition of a safety function allowing a radiator not to be left heating forever in the event of a thermometer failure
+> * **major release 2.0**: addition of the "over climate" thermostat allowing you to transform any thermostat into a Versatile Thermostat and add all the functions of the latter.

-    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"):

+![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:

+## Change security settings
+This service is used to dynamically modify the security parameters described here [Advanced configuration](#configuration-avanced).
+If the thermostat is in ``security`` mode the new settings are applied immediately.
+
+To change the security settings use the following code:
+```
+service : thermostat_polyvalent.set_security
+date:
+    min_on_percent: "0.5"
+    default_on_percent: "0.1"
+    delay_min: 60

+```
+
+# Notifications
+Significant thermostat events are notified via the message bus.
+The notified events are as follows:
+
+- ``versatile_thermostat_security_event``: a thermostat enters or exits the ``security`` preset
+- ``versatile_thermostat_power_event``: a thermostat enters or exits the ``power`` preset
+- ``versatile_thermostat_temperature_event``: one or both temperature measurements of a thermostat have not been updated for more than ``security_delay_min`` minutes
+- ``versatile_thermostat_hvac_mode_event``: the thermostat is on or off. This event is also broadcast when the thermostat starts up
+- ``versatile_thermostat_preset_event``: a new preset is selected on the thermostat. This event is also broadcast when the thermostat starts up
+
+If you have followed correctly, when a thermostat goes into safety mode, 3 events are triggered:
+1. ``versatile_thermostat_temperature_event`` to indicate that a thermometer has become unresponsive,
+2. ``versatile_thermostat_preset_event`` to indicate the switch to ```security``` preset,
+3. ``versatile_thermostat_hvac_mode_event`` to indicate the possible extinction of the thermostat
+
+Each event carries the key values ​​of the event (temperatures, current preset, current power, etc.) as well as the states of the thermostat.
+
+You can very easily capture its events in an automation, for example to notify users.
