Maximum value within 2 time stamps

hi,
i am looking for a way to find the maximum temperature value of a period with a definable start and end point. for example the maximum temperature from 01.01.2017 to 31.12.2017. can i use “maximumsince” for this? If yes, how?

Thank you very much!

No, maximumSince will return the maximum since a point in time and now
For what you what to do you will have to query the database manually, probably with SQL
What persistence are you using?

influxdb

Thanks, I was almost afraid I’d have to do it this way …
