Is it possible to make the reading of mbus devices occur every 15 minutes so that the reading occurs exactly every 15 minutes and the timestamps would be like this → 00:00, 00:15, 00:30, 00:45 etc…
or every 5 minutes
00:05, 00:10, 00:15 etc…
I got the hourly reading to work when I added 24 separate timings but this isn’t very handy way to do same every 15 or 5 minutes.
To achieve this, we need to go to Services > Modbus > Modbus TCP Client, and click edit on your created TCP device.
Then in the “Frequency” tab, select “Schedule”
In the “Schedule requests” tab enter “*:15:00” then add a new line and enter “*:30:00”.
Do this two more times for “*:45:00” and “*:00:00”. This should make the request be sent every 15th minute of every hour of the day.
The “*” Symbol is a wildcard, which means ‘any hour’ in this case
If you’d like for it to be every 5th minute of every hour, the Schedule request would look like this “*:05:00”; “*:10:00”; “*:15:00” and so on.
