Time interval overlaping for email widget for multiple event


I have 3 different event which set to call by 1sec interval.

Each event send an email once in 1 min if condition match.

As there is 15s time between emails suppose if all 3 condition match then 1st event will take priority and repete it self before any other event ready to send an email, I have check with diffrent time interval but luckily get 2 event mail.

I have tried with timeout function for email also but didn’t work.

Will be grateful to you if you can help me to resolve the issue.


Paste your formatted broken code.


thanks for the very prompt response.

one more this if i am using mq2 library then its effect the DHT11 temperature reading, i have made this code from copy & paste from here & there as i am not a programmer but some how i manage to work this code but now i stuck with above mention issue.

This limitation is only for manual Blynk.email invocation. Eventor doesn’t have this limitation. (only 100 emails per day)

Thanks for looking into matter,

Yes but with respect to code I have attached I am getting email at define interval for 1st event whrere other 2 event also above/below its set points.

Your code doesn’t seem to me correct. I think you may replace your Blynk.email instructions with corresponding Eventor events.

@Costas @Dmitriy
Thanks for your concern, but I really dont understand as I said I am copy-paste programmer.

I am getting email also but only for event which happened early.

if you can share any example then I will do changes accordingly.

I have google for similar example but didn’t find anything related.
