Hi,
TimeControl App allows sending email on a givent interval. Can i send email as soon as i see a change in my data channel? for example if a voltage is exceeded, can i send out email right away?

hmm. not there yet. I'd like ot access field 5 and i did:
DoorData = thingSpeakRead(2316538,readKey='xxxxxxxxxxxxxxxx', 'Fields',[1,5]);
but got error:
Error in /users/mss.system.nuncGe/Read Door Status Line: 22 Column: 63
Unsupported use of the '=' operator. To compare values for equality, use '=='. To pass name-value arguments using the name=value format, provide these arguments after all other inputs.
thanks

My bad. Dont mix the syntax types. I edited my original post to fix
data = thingSpeakRead(99998565,readKey='xxxxxxxxxxxxxxxx', Fields=[1,4],...);
%or
data = thingSpeakRead(99998565,'readKey','xxxxxxxxxxxxxxxx', 'Fields',[1,4in ],...);
In fact, even the other syntax combination worked, just not the way I did it.
Even this works
,...'ReadKey','xxxxxxxxxx',fields=[1,5]);

That works. Also, I was using API key from my profile, not the one assigned to each Channel. Very sorry. Now i get 401 errror, but let me fight this one.
Thanks a lot.

Definitely! Use the React app. You can check the data on a regular schedule (kinda like time control) or use 'on data insert' for the fastest response. Keep in mind that there are limits on the frequency of sending alerts and tho total number of alerts per user for a license year.

I think i got it. I use react to get the immidiate action and Matlab Analysis method to send out the email.
I tried it, but i get an error reading private channel. It is not clear to me from the examples how to read private channel fields, but i am trying below:
DoorData = thingSpeakRead(ReadKey = 'channel Read API key', Fileds=5);
and get and erro:
Error using Read Door Status Channel ID must be a positive integer.
Thanks

*edited The first argument of thingSpeakRead is the channel ID, like this
data = thingSpeakRead(99998565,ReadKey='xxxxxxxxxxxxxxxx', Fields=[1,4],...)
