[SOLVED] Unable to add Raspberry Pi-3 Device

IoT Devices
1

I’m trying to connect a Raspberry Pi3 to my STEM account, but have been encountering the following error message each time:

[INFO] Attempting to send data
(404, {u’message’: u’The request was not found.’, u’code’: 404001})
[ERROR] Could not send data after 5 attempts, please check your token credentials and internet connection
[INFO] finished

Here is what I’ve entered, with the token omitted for obvious reasons:

import time
import requests
import math
import random

TOKEN = “XXXX-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX” # Put your TOKEN here
DEVICE_LABEL = “Node Gamma” # Put your device label here
VARIABLE_LABEL_1 = “temperature” # Put your first variable label here
VARIABLE_LABEL_2 = “humidity” # Put your second variable label here
VARIABLE_LABEL_3 = “position” # Put your second variable label here

def build_payload(variable_1, variable_2, variable_3):
# Creates two random values for sending data
value_1 = random.randint(-10, 50)
value_2 = random.randint(0, 85)

# Creates a random gps coordinates
lat = random.randrange(34, 36, 1) + \
    random.randrange(1, 1000, 1) / 1000.0
lng = random.randrange(-83, -87, -1) + \
    random.randrange(1, 1000, 1) / 1000.0
payload = {variable_1: value_1,
           variable_2: value_2,
           variable_3: {"value": 1, "context": {"lat": lat, "lng": lng}}}

return payload

def post_request(payload):
# Creates the headers for the HTTP requests
url = “http://stem.ubidots.com”
url = “{}/api/v1.6/devices/{}”.format(url, DEVICE_LABEL)
headers = {“X-Auth-Token”: TOKEN, “Content-Type”: “application/json”}

# Makes the HTTP requests
status = 400
attempts = 0
while status >= 400 and attempts <= 5:
    req = requests.post(url=url, headers=headers, json=payload)
    status = req.status_code
    attempts += 1
    time.sleep(1)

# Processes results
print(req.status_code, req.json())
if status >= 400:
    print("[ERROR] Could not send data after 5 attempts, please check \
        your token credentials and internet connection")
    return False

print("[INFO] request made properly, your device is updated")
return True

def main():
payload = build_payload(
VARIABLE_LABEL_1, VARIABLE_LABEL_2, VARIABLE_LABEL_3)

print("[INFO] Attemping to send data")
post_request(payload)
print("[INFO] finished")

if name == ‘main’:
while (True):
main()
time.sleep(1)

What am I doing wrong here?

Hello dear user,

Thank you for sharing your questions with the community.

Following up, please note that device and variable labels cannot contain blank spaces, in that sense, can you please try again replacing the blank space in the device label with a dash (-), so the device label should look like node-gamma ?
Also, please note that the official server address for sending data for industrial and STEM accounts is “industrial.api.ubidots.com”. Please refer to our API documentation for further information.

Once you’ve implemented the changes please let me know how it goes.

Aha, that was the problem! Thanks a bunch!
