Programming question

[Techman]

I have a simple program that runs in a time slot and that turns on a bathroom fan if the humidity (reported from a wireless thermostat) exceeds a certain number and turns it off if the humidity goes below that number. The else line currently reads "else set bath fan off"

 

How can I also program the switch to turn on the fan manually and stay on until I manually turn it off thus overriding the above program?

I do this using a variable to determine if the fan was manually turned on or not. Something like this:

If 
  (  Control Bathroom Fan is Switched On
  Or Control Bathroom Fan is switched FastOn
  )
  And 
  (  Control Bathroom Fan is not Switched Off
  or Control Bathroom Fan is not Switched Fast Off
  )

Then
  $i.AutoFanDisable=1

Else
  $i.AutoFanDisable=0

 

If 
  #s.BathroomHumid >= 65
  And i.AutoFanDisable=0

Then
  Set Bathroom Fan On

 

If $s.BathroomHumid < 65
  And i.AutoFanDisable = 0

Then
  Set Bathroom Fan Off

Xanthros' program should work beautifully (and thanks for sharing) but my question is, How are you reading the wireless thermostat / humidistat values via ISY? That's exactly what I've been hoping to do, but didn't know was possible. I formerly used HomeSeer with Oregon Scientific sensors and an RFXCom, and temp / humidity is my last frontier in terms of replacing it with ISY and my Elk. Thanks for any info you can share.

The 2441ZTH reports temp and humidty to the ISY. These values can be checked in an ISY Program

Ah - Makes sense - Thank You!

 

I keep hoping for some way to read remote temp / humidity sensors (like those from Oregon Scientific) into the ISY or the Elk. It's the last thing I need to eliminate a PC from my system.
