cURL-Error when using GET

Hey there,

I am currently trying to get some values out of my openHAB-System (SmartHome). All the items there are exposed via REST-API to my home network.

When I try to GET the values into xibo I get an cURL-error.

Here is the link:

And the error i get:

Within my browser I can successfully get the JSON-Data of the item:

{"link":"http://192.168.20.21:8080/rest/items/KOSTALPIKOIQ100StatisticHomeconsumptionFromPVYear","state":"2361.4120125100007 kWh","stateDescription":{"pattern":"%.2f %unit%","readOnly":true,"options":[]},"editable":false,"type":"Number:Energy","name":"KOSTALPIKOIQ100StatisticHomeconsumptionFromPVYear","label":"Heimverbrauch PV (Jahr)","tags":[],"groupNames":["gKostalGleichrichter"]}

The error I get reads:
"Daten für Watson Batterie können nicht abgerufen werden, da cURL error 61: Unrecognized content encoding type. libcurl understands deflate, gzip content encodings. (see https://curl.haxx.se/libcurl/c/libcurl-errors.html)."

Can anyone point me in the right direction?
Thank you!

It seens that the server is local to your network (192.168…). Does your Xibo Server has access to this address ?
Besides that, your test is pointing to a different endpoint (KOSTALPIKOIQ100StatisticHomeconsumptionFromPVYear) then your dataset source (RobotWatsonBattery). Did you test in your browser using the same endpoint ?

Thanks for the reply! :wink:

Besides that, your test is pointing to a different endpoint

That’s because I tested another endpoint, without success.

Did you test in your browser using the same endpoint ?

Yes, Sir! I have postet the wrong JSON. Not the best idea to make this thing more confusing than it has to be, I guess. :see_no_evil:

Using the right endpoint:

{"link":"http://192.168.20.21:8080/rest/items/IRobotWatsonBattery","state":"100","stateDescription":{"pattern":"%.0f","readOnly":true,"options":[]},"editable":false,"type":"Number","name":"IRobotWatsonBattery","label":"Battery","tags":[],"groupNames":["gRoomba","gStart"]}

Does your Xibo Server has access to this address ?

I’m quite positive they can reach each other, the servers are docker container on the same machine, working with different ports. (Xibo: 80 and openHAB: 8080).

When I try to fech the root of items, i get a response with all the data from my Smarthome.

But there are hundreds of items with different values.

Any idea how, in this example, i could fetch the value for the “state”: “NULL” entry for AwtrixInfoRestmuell?
