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

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?
Over at Reddit, a MATLAB user asked about when to use a script vs. a live script. How would you answer this?
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 would tell myself to understand vectorization. MATLAB is designed for operating on whole arrays and matrices at once. This is often more efficient than using loops.
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.
Dear Community,
Since few weeks it looks like I have lost the ability to move cards order in the channel view. I used to be able to to so.
I tried with different browser and even on mobile and it does not work anymore. Did missed something ? Is this feature been removed ?
Thanks.
Tengo semanas trabajando con la app y al subir informacion me aparece que la ultima entrada fue hace menos de un minuto pero las gráficas no se actualizan, ya intente abrir la app desde diferentes navegadores,y dispositivos, en modo incognito, desabilitar extenciones y no obtengo resultados.
I am trying t set up a cellular Particle Boron and Sensor to track my well water levels but the data is not showing up in Thingspeak. I have activated and flashed code to the device, created a Particle account, a Thingspeak account (and channel), and a Webhook. Things mostly work as they should and I can even see the data from the sensor in my Particle Console "Events", but nothing seems to arrive in the Thingspeak Channel. I am looking for technical advice.

Hello,
it's been a couple weeks that the webrowser client seems to have issues for me.
I can't move the chart with my mouse anymore. And the Average option doesn't do anything, it is always displaying all the datapoints.
Same with the type of points, it is stuck on line type whatever I ask.
Also it will not update the page automatically when new points are uploaded, I have to hit F5 to refresh myself.
I can still control the number of days displayed though.
I tried on brave, firefox and edge and it all behaves the same.
Edit : I see that there are already multiple threads referencing some of those issues already. So the moderator can delete the thread if he feels like it is unecessary.
I get the following error message when using a DELETE command.
I am using the correct api_key and channel ID Error Response: { "status": "401", "error": { "error_code": "error_auth_required", "message": "Authorization Required", "details": "Please provide proper authentication details." } }
I just cannot find out what I'm doing wrong. I've used Postman and Curl apps.
Can anyone help?
how can I do to get those informations?
Ich erinnere mich, dass die Visualisierungsfenster verschoben werden konnten. Das geht nicht mehr? Wer kennt den Trick?
I can't or it's not working anymore to change the position of the widgets on the channel panel.
I tested on Chrome and Firefox.

I wanted to say that I am thoroughly enjoying my ThingSpeak channels and I often discuss with friends and associates the technical and documentative aspects of the MathWorks/MatLab/ThingSpeak platform and all the possible benefits for engineers, researchers, scientists and students across the globe.
My pubic channel demonstrates to them how useful it is to see simple data in a visually intereresting way. I hope my efforts will bring ThingSpeak more subscribers in the new year.
If there are any questions, let me know. (I owe Christopher a story here about my Alaska system. Soon......)

edited update, only one channel used publically now in 2025. I still owe CS a story...
I am sending data to Thingspeak chanels from an ESP8266. I am saving data on the ESP memory which is collected at 5 minute intervals . I have created a trigger function which sends the data on demand in batches from the memory, which means there could be varying number of Data points from say 10 to 50.However I have notice recently whilst my code tells me the data points have been transmitted not all get recorded in thingspeak, are there restrictions which cause this problem and if so what is the solution please?
