TransformationService of type 'SCALE' is unavailable

Add-ons Other
1

Hi,

I use a file UvIndex.scale in my sitemap:

Text item=UvIndex
  label="UV-Index [SCALE(UvIndex.scale):%d]"
  icon="sun"

However, it isn’t working anymore, get this error:

couldn't transform value in label because transformationService of type 'SCALE' is unavailable

When looking for it, OH2 reports it installed and started.

openhab> feature:list |grep transformation-scale
openhab-transformation-scale                │ 2.4.0.SNAPSHOT   │ x        │ Started     │ openhab-addons-2.4.0-SNAPSHOT │ Scale Transformation

What to do next?

Using 2.4.0~20180701105417-1 on Debian9 with manually installed openHABian.

Cheers,
Marianne

This shouldn’t be the reason, but try to apply the transformation in your *.items file entry
I haven’t used xforms in sitemaps. Not sure if they work there (I see no reason why not)

3

Putting it to the .items file makes no difference (I was always using it in sitemaps only and it worked).

4

then you have all the elements to open up an issue on github :slight_smile:

by the way, sometimes I get the same for the MAP xformation
A simple restart of the OH2 service (after the first startup following an upgrade) solves this one.

Service restart is the first I try when something unusually happens and I’m running beta :smiley:
But unfortunately, the error persists…

7

same to me, just upgraded openhab and now SCALE doesn`t work anymore.
I´m on openHAB 2.4.0~20180626235718-1 (Build #1304)

Yes I have same problem, scale transformation doesn’t work anymore
I have been tied up with other things before realising that.
@maintainers, is that eclipse or OH to report to?

@vzorglub: GitHub search will lead you to ESH (and btw, for core functionality it’s nearly always ESH) :slight_smile:

Edit: There was a bigger refactoring on the transformation service 5 days ago (PR #5697). Maybe it’s caused by this one. So when you ping triller-telekom in your issue, you might get help a bit faster :wink:

Hey, I opened #5842 at Eclipse SmartHome issue tracker.

Thanks

Thanks a lot :green_heart: I was too busy to do so.

Sorry, abstract classes in combination with OSGi services are evil…

I have fixed it in https://github.com/eclipse/smarthome/pull/5843

Should be available once a new ESH stable (https://ci.eclipse.org/smarthome/job/SmartHomeDistribution-Stable/) is built and openHAB has picked it up afterwards.
