“A friend in need is a friend indeed, a friend with weed is better” ~ Placebo

What I do Is I have a threshold. of switching on above say 75% and switching off below 70%. So it doesn’t have a set time. It’s just making sure things come down to at least 70% before it switches off. It does get more complex in winter as humidity tends to be higher by default, but I am playing around with the thresholds to figure out the optimal percentages. a fan on it’s own cant get the humidity down to below the general humidity in the area. Nonetheless. Fun to play with and works like a bomb.

For me one of my favourites are my extractor fan control in my bathrooms. I have a switch on the fan and a humidity sensor close by. Turn on the shower and the extractor will turn on until the humidity is lowered enough, then switch off. In addition I have a static programmable button to press should you need it for other reasons. I just love the world of entities and how they link together to make something functional.
