[SOLVED] Get http request


I have the following item:
String e2_chambre_rue_Hue “E2 Chambre rue Hue group” { http="<[]" }

When I save it, I get the following error:
14:41:50.457 [ERROR] [el.item.internal.GenericItemProvider] - Binding configuration of type ‘http’ of item ‘e2_chambre_rue_Hue’ could not be parsed correctly.

I don’t understand because this url is working in a browser and this is a standard url…

According to the docs an incoming HTTP config has the following format:


You are missing the refresh interval and transformation rule.

I get the same error. What I miss is the transformation rule to use when obtaining a single number from the url. How can I parse the value retrieved from url “http://x.x.x.x/now” that deliver an integer?

Post your item.
Post the FULL http response and highlight the number that you want


Writing “” in my browser returns realtime power usage as an integer wattage, for instance “4732”. This number I would like to present in a gauge, powerNow.

This is the entry in my items.items file:

Number powerNow “Power [%.2f °kW]” { http="<[]" }

I have also defined a thing:

Thing hanmodul “Power [%.2f °kW]” { http="<[]" }

In my /etc/openhab2/services/http.cfg i have included (not needed in 2.0?):


I am certain this is inciorrect, but cant figure out how to correct it.

You don’t need to define a thing. Delete it.

Your item should be:

Number powerNow "Power [%.2f °kW]" { http="<[hanmodul:10000:JS(getValue.js)]" }

Note that I have also changed the javascript bits.
If the HTTP ONLY return this number then you don’t even need the transformation:

Number powerNow "Power [%.2f °kW]" { http="<[*))]" }

@vzorgub: Thanks a lot :smiley: This was very helpful, I will try right away

@vzorglub: The value is now read as shown in the log :slight_smile:

2018-10-30 12:58:42.545 [vent.ItemStateChangedEvent] - powerNow changed from 9152 to 9408

However, how may I show that value in my UI?

@vzorglub::smiley: Thanks, success !

Please mark the thread as solved, thanks

@vzorglub: Sorry, but I asked my question in an open issue, I didnt start it :frowning: How can I close it?

Don’t worry about it
