I need to read database from a cloud storage (e.g dropbox or onedrive) with "thingspeak". Do you know the steps?
1. database of the date and precipitations hosted in a cloud.
2. Visualize data and realize an alert system.

I used dropbox for the image on this channel. Here is the MATLAB visualization code. If you are using Dropbox, the key part is the dl=1 at the end of the URL.
myFig=figure( 'Position',[50 10 100 1000]);
bob=imread('https://www.dropbox.com/s/xxxxxxxxxxx/LoraBox_in_Flowers.jpg?dl=1');
myFig=imshow(bob);
I'm sure there is a similar process for dropbox from MATLAB for data instead of images.
The ThingSpeak Alerts API can send emails to your MathWorks account email based on channel conditions.
