notififications / alerts/ emails on change in sensor value

Designer 2.5
6

HI MIchal,

i tried the instructions at this link you suggested below but i am getting errors- i am wondering if it has to do with the OR 2.6 beta with new drools version or Java version 8

https://openremote.github.io/archive-dotorg/forums/22872974.html

below is the copy of the rule and the error messages- i hope its something simple :slight_smile: Any help is greatly appreciated.

I have 2 drl files in the rules folder - one with working set of rules and other with the rule for email for testing.

//trial email with orcbeta2.6
