Hi there, I am trying to reach out to anyone who has successfully completed the project of building a weather station using an Arduino MKRFOX1200 board, a dht11 sensor across the Sigfox and Thingspeak networks. I’ve been attempting to build the weather station over the SigFox and things.io network for over a year now but I was unsuccessful. I then found this tutorial on how to build this using Thingspeak: https://create.arduino.cc/projecthub/masteruan/arduino-mkr-fox-1200-sigfox-meteo-station-423609 . I have now been attempting to build it using this network but am still unsuccessful.
My SigFox and arduino is working. I made the arduino code convert temperature to Celsius (rather than Kelvin which is what the tutorial does). However, I am unable to access the location of the device on Thingspeak (my SigFox atlas is activated) and I am getting humidity values of approximately -30k. Please may someone assist me or give me a detailed approach on how to fix these issues. My goal is to have my thingspeak like this: https://thingspeak.com/channels/227248. I have followed the tutorial and projecthub but I cannot figure out why I am obtaining a confusing humidity reading. Please please may someone help.
Thank you so much for your time.
hello, how i can show module image in to public view.
in widget public dont show the option.
exist any code for MATLAB?
Error: The server timed out while running and assessing your solution in MATLAB CODY. How do I resolve this? My code is correct. I have run it on PC. But, when i submit in CODY the server throws an error.

Hello, I need help with this code to show the longitude and latitude from the neo6m module. When the map is displayed, it looks very close. How can I fix it?
It is for a university project I hope you can help me thanks
code:
lat = thingSpeakRead(1962341,'Fields',3,'ReadKey','ZHIVMUHTJXI4xxxx','NumPoints',10,'Timeout',50);
lon = thingSpeakRead(1962341,'Fields',4,'ReadKey','ZHIVMUHTJXI4xxxx','NumPoints',10,'Timeout',50);
geoscatter(lat,lon,'h');
geobasemap('satellite');
Hello!
The fields sometimes will update most of the times but not always. The Serial monitor shows the following output when it does not update:
while when it update it shows the following:
There is no issue with the update rate since it is more than 15 seconds.
Iam using a feather fona and the chunk of the code Iam using to send the data is the following:
if (gprsSerial.available())
Serial.write(gprsSerial.read());
gprsSerial.println("AT");
delay(1000);
gprsSerial.println("AT+CPIN?");
delay(1000);
gprsSerial.println("AT+CREG?");
delay(1000);
gprsSerial.println("AT+CGATT?");
delay(1000);
gprsSerial.println("AT+CIPSHUT");
delay(1000);
gprsSerial.println("AT+CIPSTATUS");
delay(2000);
gprsSerial.println("AT+CIPMUX=0");
delay(2000);
ShowSerialData();
gprsSerial.println("AT+CSTT=\"internet\"");//start task and setting the APN,
delay(1000);
ShowSerialData();
gprsSerial.println("AT+CIICR");//bring up wireless connection
delay(3000);
ShowSerialData();
gprsSerial.println("AT+CIFSR");//get local IP adress
delay(2000);
ShowSerialData();
gprsSerial.println("AT+CIPSPRT=0");
delay(3000);
ShowSerialData();
gprsSerial.println("AT+CIPSTART=\"TCP\",\"api.thingspeak.com\",\"80\"");//start up the connection
delay(6000);
ShowSerialData();
gprsSerial.println("AT+CIPSEND");//begin send data to remote server
delay(8000);
ShowSerialData();
delay(4000);
gprsSerial.println(str3);//begin send data to remote server
delay(8000);
ShowSerialData();
delay(6000);
gprsSerial.println((char)26);//sending
delay(6000);//waitting for reply, important! the time is base on the condition of internet
gprsSerial.println();
ShowSerialData();
gprsSerial.println("AT+CIPSHUT");//close the connection
delay(3000);
ShowSerialData();
delay(3000);
}
Thank you in advance!
Using a Thingspeak42 node with NodeRed on a RaspberryPi 4. The node is showing data is being sent but nothing gets populated on graph in Thingspeak.
I would like to have a widget to control a pump connected to Thingspeak via Talkback. I have also established a connection with thingspeak where I publish my sensor data to the channel and can visualize the data through the various widgets. But I cant find a widget or method to control the pump from a graphical perspective on the channel (like a switch or button interface where clicking them would turn the pump on or off). Thingsboard seems to have the feature, not sure of thingspeak. If anyone knows a way please do comment out. Have a great day!

Hi,
I use micro:bit and iot:bit to collect data about temperature and humidity (via BME 280, but I cant connect with ThingSpeak, but Iam connected on wifi.
What I make wrong?
Hi all
Learning home automation and found your webpage via cookbook sample code, which I cannot get work, i.e. sending a tweet. Somehow API keys should be OK as I got another sample from your page (bulkdata upload with Raspi) working just fine
Code seem to run and response is OK 200, am I just missing how to check this from twitter or? if I change API key to xxx response is 400 so
import time, os
import requests
MAX_TEMP = 19.0
MIN_T_BETWEEN_WARNINGS = 1 # Minutes
BASE_URL = 'https://api.thingspeak.com/apps/thingtweet/1/statuses/update/'
KEY = 'xxx'
def send_notification(temp):
status = 'Thingtweet: Room getting hot. room temp=' + str(temp)
data = {'api_key' : KEY, 'status' : status}
response = requests.post(BASE_URL, json=data)
print(response)
print(data)
def room_temp():
f = open('/mnt/1wire/28.55CA95F0013C/temperature','r')
room_temp = f.read()
return float(room_temp)
while True:
temp = room_temp()
print("room Temp (C): " + str(temp))
if temp > MAX_TEMP:
print("room TOO HOT!")
send_notification(temp)
print("No more notifications for: " + str(MIN_T_BETWEEN_WARNINGS) + " mins")
time.sleep(MIN_T_BETWEEN_WARNINGS * 1)
time.sleep(10)
i have imported data from a chanel, edited it and re uploaded again,
it returns error message when i upload it.
it says "The uploaded file was not imported because it is empty"
Mathworks returns also a message to my email saying "Timestamp already in channel."
Hello,
Can someone please give me a hint how the settings at Tasmoto have to be made in order to send data via MQTT to ThingSpeak.
Halil Kemal has an open channel tag: tasmota where this seems to work.
Thank you in advance for your support.

Dear community,
I would like to develop a fermentation model with 4 ODEs, one of which contains variable y. A "repeated assignment", e. g. y=5x+5, contains variable x that has been measured each second. These data (columns with time and corresponding value x in each row) are recorded in the Excel file.
Does anyone have any suggestion how to implement this in symbiology?
Thank you very much in advance,

How can I export data other than downloading it as a CSV file?
I want to embed the graphs in a website, how can I do that?
OR
How can I export data and display it on my own in the website?
Hi,
I want to develop a PK model based on some PK data. The PK data seems to display 2 peaks when one initial dose is given.
I would like to give one dose. A fraction of this dose (fr) is absorbed following the linear relationship - ka*Drug the other fraction (1-fr) is absorbed following a linear absorption (ka1*Drug) with a Tlag (it maybe a zero order). The fraction fr is unknown so it must be estimate.
Does anyone have can provide any suggestion to implement this in symbiology or provide a link where I can look?
Thank you very much in advance,

Hello everyone! does anyone know how to use the simulink write block for mobile android? I am attaching a cell phone error message. Thank you!
I have a species which is absorbed in a zero-order manner. I want to model the reaction rate as "UptakeRate*ActiveState". So I can give value of 1 or 0 to ActivateState to control the active state of this process. The species itself is under control multiple processes, so I want to use Event to automatically change the active state of absorption.
However, when I use these two events:
Event 1，trigger: species > 0, Function: ActiveState =1; Event 2, trigger: species <=0, Function: ActiveState=0
The simulation seems to be stuck without stop.
Is there any way to solve this ? Thanks
Hello
I am Jos
i have made a program for upload data to mine channels in pytython 2.7, now I am forced to go to 3.9 and I cannot get the program running
code for 2.7
import httplib
import urllib
def WriteData():
while True:
params = urllib.urlencode({'key': 'xxxxxxxxxxxxxxxx', 'field1': '0.021'})
headers = {"Content-typZZe": "application/x-www-form-urlencoded","Accept": "text/plain"}
conn = httplib.HTTPConnection("api.thingspeak.com:80")
try:
conn.request("POST", "/update", params, headers)
response = conn.getresponse()
print (response.status, response.reason)
data = response.read()
conn.close()
except:
print ("connection failed")
break
can someone help me with this code?
Dear Community,
I'm new on ThingSpeak for nearly 4 weeks and I'm struggling to compute some MATLAB data. Mostly because I don't know the syntax.
I have a hourly graph of solar production in kW, I'm taking a sample every 20 seconds, and I would like to aggregate the data on a daily basis in kWh.
I guess I need to select the last 7 days of data using some thingsread function, add the data into an array and compute the daily data into an average/sum ... As you can see, I mostly got the mechanics but I'm struggling to create the car ;) Is there anyone kind enough to assist me ?
Thansk a lot !
