Mysql and persistence extensions

  • Platform information:
    • Hardware:Intel
    • OS: Ubuntu Linux 18.04
    • Java Runtime Environment: 1.8.0_181-b13
    • openHAB version: 2.5.12

I’m successfully using the persistence extension Item.averageSince(). But when I try to use other methods like deviationSince() or varianceSince() I always get the following error:

2021-05-30 11:39:38.594 [ERROR] [ntime.internal.engine.RuleEngineImpl] - Rule 'Light Sensors Trends': 'deviationSince' is not a member of 'org.eclipse.smarthome.core.library.items.NumberItem'; line 96, column 55, length 58

The source looks like this:

logInfo("deviation", "deviation is: " + BrightnessStreet.deviationSince(now.minusMinutes(15)))

If I replace the devationSince with averageSince, it works.
I’m using a Mysql Persistence 1.14.0.

Do I have to enable the other persistence extensions somewhere?

Thanks for help!

These are new features not available to you.

OH 2.5 extensions -

Ah, wasn’t aware of this! Thanks for mentioning!
