Blind Bathroom Fan Control
Posted: Thursday 19 July 2018 9:16
Ciao,
while I'm restructuring my bathroom, I played around with Zwave and other devices....
The result is an automatic fan control based on light and humidity
the actors are:
- Light switch (in my case zWave)
- Fan Switch (in my case zWave)
the sensors are:
- Temp/Humidity Device (in my case a rf433 device from Oregon)
The other stuff needed are:
- Numeric Variables with the Humidity Trigger (min/max)
How it works:
When you switch on the light the fan start, when the light is OFF or have been switched off the script evaluate the humidity value and act the fan accordingly
If over the MAX value it switch it on
if below the min value it switch off
the triggers are:
- light device
- Temp/Hum change
SCRIPT:
I've installed it 2 days ago and seems to work fine
hope you will find it useful!
