Problem - Smartthings Particle Photon Integration

Developer Programs Writing Device Types
1

I am having trouble getting two programs to talk together.

I am receiving the following error when running my current programs:

error groovyx.net.http.HttpResponseException: Unauthorized @line 72 (sendToDevice)

How do I fix this?

Here is my SmartThings Device Type:

preferences {
    section("Your Particle credentials and device Id:") {
        input("token", "text", title: "Access Token")
        input("deviceId", "text", title: "Device ID")
        input("query", "text", title: "Query Name")
    }
}

metadata {
	definition (name: "Blinds", namespace: "luxetbono", author: "John Bono") {
		capability "Window Shade"
	}
    
    // tile definitions
	tiles {
		standardTile("switch", "device.switch", width: 2, height: 2, canChangeIcon: true) {
        	state "open", label: '${name}', action: "switch.off", icon: "st.Home.home9", backgroundColor: "#ffc300", nextState: "opening"
			state "close", label: '${name}', action: "switch.on", icon: "st.Home.home9", backgroundColor: "#00a9ff", nextState: "closing"
        	// state "opening", label:'${name}', icon:"st.Home.home9", backgroundColor:"#ffeaa5", nextState: "closing"
        	// state "closing", label:'${name}', icon:"st.Home.home9", backgroundColor:"#b7e1f7", nextState: "opening"
		}

		main "switch"
		details "switch"
	}
}

// parse events into attributes
def parse(String description) {
	log.debug "Parsing '${description}'"
	// TODO: handle 'windowShade' attribute
}

// handle commands
def open() {
	log.debug "Executing 'on'"
    sendEvent(name: 'switch', value: 'open')
	// TODO: handle 'open' command
    sendToDevice 'open'
}

def close() {
	log.debug "Executing 'off'"
    sendEvent(name: 'switch', value: 'close')
	// TODO: handle 'close' command
    // sendToDevice 'close'
}

/*ENABLE THIS WHEN YOU HAVE YOUR PARTICLE PHOTON. */

private sendToDevice(cmd) {
    // Particle API call to our photon device
    // "deviceId" will be replaced with our actual device name
    // FanControl is the name of our published function exposed by the device
    // state is our input parameter: 'on' or 'off'
    log.info(deviceId)
	httpPost(
		uri: "https://api.particle.io/v1/devices/${deviceId}/${query}",
        body: [access_token: token, command: cmd],  
	) {response -> log.debug (response.data)}
}

Here is my Particle Photon code:

boolean state = true;

void setup() {
    Particle.function("blind", blind); // Register cloud function called blind that controls blinds.
    pinMode(D7, OUTPUT);
}

int blind(String command)
{
    if(command == "open"){
        // Open window blinds.
        RGB.control(true);
        RGB.color(34, 102, 75);
        delay(4000);
        RGB.control(false);
        state = true;
        // Add state change call for Smartthings using webhooks and the CoRE SmartApp.
    } else if (command == "close") {
        // Close window blinds.
        RGB.control(true);
        RGB.color(34, 68, 102);
        delay(4000);
        RGB.control(false);
        state = false;
        // Add state change call for Smartthings using webhooks and the CoRE SmartApp.
    }
}

void loop() {
    
}

Stumbled across this while debuging my own Particle/ST issues… but the fix for you is that when you call the device endpoint like that, the access token goes in the uri…
