Script de commutation de VMC pour douche

Créer les variables dans Domoticz, à l’adresse http://adresseserveurdomoticz/#/UserVariables. Toutes les variables sont de type integer et à initialiser à la valeur 0 :


Mettre en place le script dans le menu Setup/More Options/Events, cliquer sur le « + », puis Lua, puis « All (commented »). Y coller le script suivant :

    This script controls the humidity in a typical bathroom setting by detecting
    relative rises in humidity in a short period.
    Of course it requires a humidity sensor and a binary switch controlling a fan/ventilator.
    (there is no provision for variable speed ventilators here!)

    How it works (assuming the default constants as defined below):
    Save the script as time triggered!!

    Every 5 minutes a reading is done.
    Every reading is stored together with the previous reading in two user variables (humidityTmin5 and humidityTmin10).
    So it has two reading stored over the past 10 minutes.
    It then takes the lowest of the two and compares it with the current reading and calculates a delta.
    If the delta is 3 or higher (see constants) then the fan will be turned on, it calculates the target humidity and the 'humidity-decrease program' is started (fanFollowsProgram=1).
    From then on, every 5 minutes the current humidity is compared to the stored target humidity. Basically if that target is reached, the fan is turned off and the 'program' is ended.
    Of course, it is possible that the target is never reached (might start raining outside or whatever).
    Then there is a failsafe (FAN_MAX_TIME) after which the ventilator will be turned off.
    Also, it will detect if the ventilator is manually switched off during a program or when it is switched on before the program starts.

    Along the lines it prints to the log and sends notifications but of course you can turn that off by removing those lines.
