Enclencher la VMC

[leraver]

Bonjour
Je cherche a commander ma VMC, j'ai dai un blocky comme suit:

ScreenShot035.jpg (34.14 Kio) Consulté 10546 fois

Mais il n'a pas l'air de vouloir enclencher .

Auriez vous des idées? de ce qui cloche?

bonjour

j'ai eut les memes soucis et trouver cette solution:

if humidite cuisine >= 60 or humidite salle bain >=60
do set prise = on
else if humidite cuisine <59 or humidite salle de bain <59
doset prise = off

[leraver]

yes pas bete ca.
Je teste ce soir

Salut,
Il y a un script sur le wiki qui contrôle une augmentation du niveau d'humidité plutôt qu'une valeur.
Bien plus représentatif car ça ne sert à rien de ventiler s'il pleut dehors, l'humidité sera de toute façon élevée.
Idem l'été, un faible niveau d'humidité ne signifie pas que l'on à pas besoin de ventiler..

[leraver]

Ah.... Pas trouvé

[vil1driver]

Je l'ai par là, je te le mettrai ici..
Le principe est sympa, il prend même en compte le fait que tu ai mis le chauffage, car la chaleur fait baisser l'humidité relative...etc..

Toute une histoire..

Ps:voila pourquoi je préfère lua, sauvegarde/partage rapide et facile

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):
Every 5 minutes a reading is done. Every reading is stored together
with the previous reading and is stored in two user variables (humidityTmin5 and humidityTmin10).
So it has two reading over the past 10 minutes.
It then takes the lowest of the two and compares it with the latest 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.

Merci
je fais regarder ce que je peu faire evec cela.
Deja le traduire...

[deennoo]

Si je peux me permettre une chose, il ne faut pas couper la VMC, un courant d'air prend du temps a ce mettre en place, une salle de bains est par définition une pièce constamment plus humide que les autres il vaut mieux jouer sur la vitesse.

En normal : petite vitesse
en demande de ventilation : Grande vitesse

idem pour une hotte aspirante de cuisson, pour un bon fonctionnement il faut la mettre en route avant cuisson et encore 10 minutes aprés.

[leraver]

Bien sur c'est claire.
Me concernant c'est du on ou off ( cause renovation... par organisme de HLM...) et de nuit il faut avouer que le bruit est plutot penible.
Sachant que nous somme passé d'une ventilation "naturel" a une forcée, si je peu la couper lorsque elle n'est pas vital...
