Hi, I’m trying to tweak the ‘The first smartapp’. What I need is have it on turn on a timed light on sunny days (with motion),but leave the light on (again on motion) when dark or cloudy.
I have an area that needs a little more light in the day time. There is a unlighted section next to this area. Right now I keep the light on at all times.
Here’s what I have tried. I’m not a programmer and it looks like there are too many things I don’t know. I would appreciate some ones help in getting this to work.
preferences {
section(“Turn on this light:”) {
input “theswitch”, “capability.switch”, required: true
}
section(“Choose your motion detector:”) {
input “themotion”, “capability.motionSensor”, required: true, title: “Where?”
}
section(“Turn off when there’s been no movement for”) {
input “minutes”, “number”, required: true, title: “Minutes?”
}
section(“Choose your light sensor:”) {
input “lightSensor”, “capability.illuminanceMeasurement”
}
section(“What LUX level is considered too ndark?”) {
input “luxLevel”, “number”, required: true
}
}

def initialize() {
subscribe(themotion, “motion.active”, motionDetectedHandler)
subscribe(themotion, “motion.inactive”, motionStoppedHandler)
subscribe(lightSensor, “illuminance”, illuminanceHandler)
}
def motionDetectedHandler(evt) {
log.debug "motionDetectedHandler called: $evt"
theswitch.on()
}
def motionStoppedHandler(evt) {
log.debug "motionStoppedHandler called: $evt"
runIn(60 * minutes, checkMotion)
}
def checkMotion() {
log.debug "Im checking Motion Now - scheduled method"
def motionState = themotion.currentState(“motion”)
def darkness = settings.luxLevel.toInteger()
log.debug "Lux level for darkness is $darkness"
def lightSensorState = lightSensor.currentilluminance
log.debug "CurrBright = $lightSensorState"
if (motionState.value == “inactive”) {
def elapsed = now() - motionState.date.time // get the time elapsed between now and when the motion reported inactive
log.debug "elapsed is $elapsed"
def threshold = 1000 * 60 * minutes // elapsed time is in milliseconds, so the threshold must be converted to milliseconds too
log.debug "threshold is $threshold"
if (elapsed >= threshold && darkness <= CurrBright) {
log.debug "Motion has stayed inactive long enough since last check ($elapsed ms): turning switch off"
theswitch.off()
} else {
log.debug “Motion has not stayed inactive long enough since last check ($elapsed ms): doing nothing”
}
} else {
// Motion active; just log it and do nothing
log.debug “Motion is active, do nothing and wait for inactive”
}
