Whole house fan smart app help please

Developer Programs Writing SmartApps

I need help figuring out how to alter the code of this app. It currently requires at least one window to be open to run but I would like to modify it so that it requires all selected windows to be open to run.

Here is the code below for the smart app…

I’m new to this stuff so I’m sorry if I’m not much help. but if you are unable to get a solution via coding you may be able to accomplish the same thing by using CoRE.

you can find more info on this smartthings app here … CoRE

Was doing some reading while trying to work on some code for myself and ran across this. I think you’ll be able to find your answer here…

Smartthings Device ref-doc

preferences {
      section() {
        // prompt user to select a device that supports the switch capability.
        // assign the chosen device to a variable named "theswitch"
        input "theswitch", "capability.switch"
    }
}
...
// access Device instance using the input name:
def deviceDisplayName = theswitch.displayName
...

If you have door and window contact sensors connected to your smartthings you can add a new “switch” input for each door/window you want to verify is open or closed in your house. You can then use “switch.getStatus()” to check if each switch is open or closed.

How getStatus() works:

Here’s an example of it in use with multiple switches to get the switch name and temperature when used with thermostat: (you may try to use switch.currentValue(“switch”) to see what it returns)

preferences {
    section() {
        input "theswitch", "capability.switch"
        input "thetemp", "capability.temperatureMeasurement"
    }
}
...
def switchattr = theswitch.currentValue("switch")
def tempattr = thetemp.currentValue("temperature")

log.debug "current switch: $switchattr"
log.debug "current temp: $tempattr"

// switch attribute returned as a string
log.debug "switchattr instanceof String? ${switchattr instanceof String}"

// temperature attribute returned as a Number
log.debug "tempatt instanceof Number? ${tempattr instanceof Number}"

...

Here’s another example from the same page: (Selecting multiple switches at one time and running a loop to check the status of each)

preferences {
    input "switches", "capability.switch", multiple: true
}

def installed() {
    switches.each {
        log.debug "switch id: ${it.id}, model name: ${it.getModelName()}"
    }
}

Hope this helps!
I’ll continue on my project now :smile:
