@Frank_Pepperyellow you should be able to use the code in this series with only minimal changes. The Python/Jython part of these tutorials did not change from OH2 to OH3, but parts for OH did so you may need to change things that interact with OH yo work in 3. Largely the only thing you need to change will be DateTime related. OH2 had Joda DateTime installed and it was encouraged to use that, OH3 does not have Joda so you must use Java’s ZonedDateTime instead (which is also available in OH2).
In regards to the error you saw:
```
Use code fences like this when posting logs or code.
Enclosing the log or code in 3 ticks, like you see
above and below here, will make it look like this
block
```
And I’m guessing you have installed the original Helper Libraries and not my update version that supports OH3. You can find it here:
