I found read API key but there is no option for the read channel id
Happy year of the dragon.
Is anyone having issues downloading the entire data from a channel? I usually include this line to the url but it no longer works: /feed.csv?days=1000000. Any suggestions on a way forward?
Greetings to all MATLAB users,
Although the MATLAB Flipbook contest has concluded, the pursuit of ‘learning while having fun’ continues. I would like to take this opportunity to highlight some recent insightful technical articles from a standout contest participant – Zhaoxu Liu / slandarer.
Zhaoxu has contributed eight informative articles to both the Tips & Tricks and Fun channels in our new Discussions area. His articles offer practical advice on topics such as customizing legends, constructing chord charts, and adding color to axes. Additionally, he has shared engaging content, like using MATLAB to create an interactive dragon that follows your mouse cursor, a nod to the upcoming Year of the Dragon in 2024!
I invite you to explore these articles for both enjoyment and education, and I hope you'll find new techniques to incorporate into your work.
Our community is full of individuals skilled in MATLAB, and we're always eager to learn from one another. Who would you like to see featured next? Or perhaps you have some tips & tricks of your own to contribute. Remember, sharing knowledge is a collaborative effort, as Confucius wisely stated, 'When I walk along with two others, they may serve me as my teachers.'
Let's maintain our commitment to a continuous learning journey. This could be the perfect warm-up for the upcoming 2024 contest.
Can you see them?
I have been procrastinating on schoolwork by looking at all the amazing designs created in the last MATLAB Flipbook Mini Hack! They are just amazing. The voting is over but what are y'all's personal favorites? Mine is the flapping butterfly, it is for sure a creation I plan to share with others in the future!
Now it's just a dial and pointer. There used to be a numeric value underneath.
I mentioned this in another thread about the column function not working, but thought maybe it needs it's own thread to be noticed.
This broke about the same time as the line/column problem and the not being able to move windows around anymore.
As of an hour ago my Visualisation stopped working, suddenly returning an empty matrix for 'old' (2019) data retrieved. It has been working fine all day and historically. New data being uploaded today is being retrieved fine. My code hasn't changed.
Downloading and checking, all data prior to 29-Nov-2023 has gone.
Has something changed server side?
One of my colleauges, Michio, recently posted an implementation of Pong Wars in MATLAB
- Here's the code on GitHub.https://lnkd.in/gZG-AsFX
- If you want to open with MATLAB Online, click here https://lnkd.in/gahrTMW5
- He saw this first here: https://lnkd.in/gu_Z-Pks
Making me wonder about variations. What might the resulting patterns look with differing numbers of balls? Different physics etc?
Some years ago I installed a IOBridge IO-204 device from https://iobridge.com/
This was used to remotely control and monitor heating of a building trough the "ioApp" or trough the widgets on their webpage.
Seems like the support for the app and the IObridge webpage (including widgets) is discontinued and the webpage now links to ThingSpeak without any further information.
I cannot find any information about using ThingSpeak to communicate and control an ioBridge IO-204 device?
If it is possible I would really appreciate some help getting starter to do the setup.
Thanks in advance.
We are excited to unveil the ‘Open in MATLAB Online from File Exchange’ feature, which offers MATLAB users a new way to open File Exchange content!
Previously, to experiment with File Exchange code, you were required to download the file and execute it in MATLAB. But now, there's a quicker and easier way to explore the code!
You will find the ‘Open in MATLAB Online’ button next to the ‘Download’ button (see the screenshot below). A simple click transports you directly into the MATLAB Online workflow. It's that straightforward and effortless.
We strongly encourage you to try this new feature. Please share your questions, comments, or ideas by responding to this post!
Buenas noches. Tengo una estación meteorológica contruida con Arduino, desde hace 4 años y funcionando perfectamente, y veo los datos mediante ThingSpeak. El problema es el que se ve en la imagen:
La méteo, gestionada por una placa Arduino Wemos D1 Mini Pro, una placa solar, una batería y un sensor BME280, funciona cada hora. És decir, está hivernando y cada hora, durante un breve lapso de tiempo, despierta y emite los datos. ThingSpeak los envía a mi ordenador. El problema es que durante 4 años, ha estado enviando, cada hora, una sola lectura de los datos, però ahora envía dos o tres datos con minutos de diferencia, con lo que la lectura y procesamiento de estos datos, se ha vuelto inestable.
No se si es debido a una reinstalación del sistema operativo, debido a un problema que he tenido con el SO, o a qué, pero quisiera volver a ver los datos de forma única, un solo dato cada hora. He sustituido la placa Arduino por otra, pero el problema persiste sin solucionarse, con lo que deduzco que posoblemente deba atribuirse al programa ThingSpeak.
Sería posible solucionar este problema? Hay alguna manera de acceder a modificar, específicamente, esta configuración para volver a mostrar únicamente una lectura por hora?
Gracias por la atención y la ayuda
Salu2 cordiales
I'd like to give someone quick access to a private channel via a URL. Basically, I'd like to place a QR code sticker on the device so that any time they want, they can quickly check out how the device data is trending by pointing their cell phone camera at the QR code and clicking. Ez-peezie. This works with a public channel because no authentication is required,
Is there a way to do this with a private channel? I was hoping I could add their email address to the sharing tab for the channel and then, after they had logged into Thingspeak on their phone with their own account, perhaps their browser state would be retained and when the camera launched a browser tab with the url, it would work. But alas, I've probably over-simplied the credentials aspect betwen the camera app and the brower app. At least it doesn't seem to work with Safari or Chrome on IOS.
Does anyone know of an easy way (easy for the end user) to make this work?
It is not possible to link ThingTweet with Twitter. When I authorize through "Authorize ThingTweet to access your account?", it says "Redirecting you back to the application. This may take a few moments" and logout in thingtweet. Its looping. How to fix this issue?
It didn't work even after deleting cookies or trying with MS edge browser as detailed here

Sending temperature and humidity values to a thingSpeak channel using a NodeMCU(esp8266) and the ThingSpeak library. The problem is that the graphs do not update dynamically even if values are sent and received regularly. To update the graphs I have to refresh the page every time. The numeric displays and other widgets update regularly. How can I solve the problem?
I'm having problem in its test 6 ... passing 5/6 what would be the real issue..
am wring Transformation matrix correct.. as question said SSW should be 202.5 degree...
so what is the issue..

I cannot get any of my charts to be interactive using matlab. I need to be able to zoom into a chart and I cannot get any interactivity. In its purest from shouldnt this allow me to zoom into a chart?
plot(time, data);
% Enable zooming
zoom on;

Ich habe das Problem das ich immer nur 1 Tag aufzeichnen kann (siehe Anhang), obwohl ich den Parameter au 15 tage gestellt habe.
