OH2 to OH3 rule Timestamp not working

Setup, Configuration and Use Migration
1

I am trying to get an OH2 rule to work with OH3

Rule that works with OH2 and creates a timestamped .jpg file:

var FrontDoorCamA = "FrontDoorA"+ now.toString ("MM-dd-yyyy_HH-mm-ss") +".jpg"
executeCommandLine("wget http://user:pass@192.168.xx.xx:port/Streaming/Channels/1/picture -O /usr/share/openhab2/pictures/" +FrontDoorCamA)

I have made these changes, but it seems like I am missing something:

var FrontDoorCamA = "FrontDoorA"+ ("MM-dd-yyyy_HH-mm-ss") +".jpg"
executeCommandLine("wget", "http://user:pass@192.168.xx.xx:port/Streaming/Channels/1/picture", "-O", "/usr/share/openhab/pictures/" +FrontDoorCamA)

This only creates a file called: FrontDoorAMM-dd-yyyy_HH-mm-ss.jpg

I have also tried the following but noting that works:

var FrontDoorCamA = "FrontDoorA"+ ZonedDateTime.now() +".jpg"           // no errors, no file created
var FrontDoorCamA = "FrontDoorA"+ (ZonedDateTime now()) +".jpg"         // no errors, no file created
var FrontDoorCamA = "FrontDoorA"+ ("ZonedDateTime now()") +".jpg"         //no errors, FrontDoorAZonedDateTime.now().jpg
var FrontDoorCamA = "FrontDoorA"+ "ZonedDateTime now()" +".jpg"            //no errors, FrontDoorAZonedDateTime.now().jpg
//
var FrontDoorCamA = "FrontDoorA"+ ZonedDateTime now +".jpg"           // no errors, no file created
var FrontDoorCamA = "FrontDoorA"+ (ZonedDateTime now) +".jpg"        // no errors, no file created
var FrontDoorCamA = "FrontDoorA"+ ("ZonedDateTime now") +".jpg"     //no errors, FrontDoorAZonedDateTime.now.jpg
var FrontDoorCamA = "FrontDoorA"+ "ZonedDateTime now" +".jpg"       //no errors, FrontDoorAZonedDateTime.now.jpg
//
var FrontDoorCamA = "FrontDoorA"+ ZonedDateTime +".jpg"                 //no errors, FrontDoorAclass java.time.ZonedDateTime.jpg
var FrontDoorCamA = "FrontDoorA"+ (ZonedDateTime) +".jpg"               //no errors, FrontDoorAclass java.time.ZonedDateTime.jpg
var FrontDoorCamA = "FrontDoorA"+ ("ZonedDateTime") +".jpg"             //no errors ,  FrontDoorAZonedDateTime.jpg
var FrontDoorCamA = "FrontDoorA"+ "ZonedDateTime" +".jpg"               //no errors, FrontDoorAZonedDateTime.jpg
//
var FrontDoorCamA = "FrontDoorA"+ ZonedDateTime() +".jpg"                // failed: The name 'ZonedDateTime' cannot be resolved to an item or type
var FrontDoorCamA = "FrontDoorA"+ (ZonedDateTime()) +".jpg"             // failed: The name 'ZonedDateTime' cannot be resolved to an item or type
var FrontDoorCamA = "FrontDoorA"+ ("ZonedDateTime()") +".jpg"          // no errors, FrontDoorAZonedDateTime().jpg
var FrontDoorCamA = "FrontDoorA"+ "ZonedDateTime()" +".jpg"            //no errors, FrontDoorAZonedDateTime().jpg

Have a look here:

Yeah, I have that page bookmarked.
I’m still stumped.

4

Why? No. 11 or 11 should be your solution

5

now.toLocalDateTime().toString()

Or with formatting.

Maybe you bookmarked 2.5 tutorial?

Working with Date only. No time.

var FrontDoorCamA = "FrontDoorA"+ now.toLocalDate().toString() +".jpg"      //creates FrontDoorA2023-02-05.jpg
var FrontDoorCamA = "FrontDoorA"+ now.toLocalDateTime().toString() +".jpg"  // creates random file:  F0BZEN~9.JPG
var FrontDoorCamA = "FrontDoorA"+ LocalDate.now() +".jpg"                   //creates FrontDoorA2023-02-05.jpg
var FrontDoorCamA = "FrontDoorA"+ LocalDateTime.now() +".jpg"              //creates random file:   FSGC3M~X.JPG
var FrontDoorCamA = "FrontDoorA"+ LocalTime.now() +".jpg"                  //creates random file:    F73IYN~M.JPG

Make it without now, because thats a java time.

var FrontDoorCamA = "FrontDoorA_"+ (new DateTimeType()).format("%1$tY-%1$tm-%1$td_%1$tH_%1$tM_%1$tS")+".jpg"

LocalDateTime.now().toString() works too, you missed the toString() after now().

9

this works too on my system. Interesting you got a random filename

logInfo("Test", "Wert: "+(new DateTimeType()).format("%1$tY.%1$tm.%1$td_%1$tH_%1$tM_%1$tS"))
logInfo("Test2", "Wert: "+now.toString)
logInfo("Test3", "Wert: "+now.toString())
logInfo("Test4", "Wert: "+LocalDateTime.now().toString())
logInfo("Test5", "Wert: "+now.toLocalDateTime().toString())

gives

This is working

var FrontDoorCamA = "FrontDoorA_"+ (new DateTimeType()).format("%1$tY-%1$tm-%1$td_%1$tH_%1$tM_%1$tS")+".jpg"      //creates good file:  FrontDoorA_2023-02-05_16_36_32.jpg

this one dosen’t work:

var FrontDoorCamA = "FrontDoorA"+ LocalDateTime.now().toString() +".jpg"        //creates random: FEHNRP~W.JPG

Thank you so much for all your help!

Did you updated to actual Java? OpenHAB uses Java 11 if I remember right

12

oh3:~$ java -version
openjdk version “11.0.17” 2022-10-18
OpenJDK Runtime Environment (build 11.0.17+8-post-Ubuntu-1ubuntu222.04)
OpenJDK 64-Bit Server VM (build 11.0.17+8-post-Ubuntu-1ubuntu222.04, mixed mode, sharing)

Very interesting the second works here with same Java version but not for you …

Maybe because you didn’t define

var string ‚variable‘ =….

But equal, your problem is solved :slight_smile:
