I’m trying to write a SmartApp to send the state of a device to a server (my VPS). The code is as follows:
preferences {
section(“Collect the motion data:”) {
input “motion_sensor”, “capability.motionSensor”, required: true
}
}
def installed() {
log.debug “Installed with settings: ${settings}”
initialize()
}
def updated() {
log.debug “Updated with settings: ${settings}”
unsubscribe()
initialize()
}
def initialize() {
// TODO: subscribe to attributes, devices, locations, etc.
subscribe(motion_sensor, "motion.active", postData)
}
def postData(evt) {
def params = [
uri: “104.160.33.4”,
// or uri: “www.baidu.com”
]
try {
httpPostJson(params) {
log.debug "Do nothing on the response."
}
} catch (e) {
log.debug "something went wrong: $e"
}
}
// TODO: implement event handlers
This SmartApp is supposed to send some data to a remote server once it is triggered by a “Motion” event.
But once I triggered the motion sensor, it outputs some debug information:
“something went wrong: java.lang.reflect.UndeclaredThrowableException”
Is there anybody can help me? Thank you very much.
