Items REST API - Add formatting flag [message #1775927]

Hi,

I am sending a query to get a list of items from openhab from a low resource device. The problem is that the returned response is very big (comparing the total memory I have in the device). I already use tagging and type in the query but even though the returned size is very big.

If possible, I suggest to add a format flag that will support different formatting, e.g., compact & full (others ?). In full mode the returned list will be the same as today. In compact mode the returned list will only be the names of the items. Using the names I can manually get each item full configuration.

Other option will be to add extra REST API but I am not sure it is needed here.

What do you think?

Hi,

we have a similar issue regarding REST query with filters already open on github, see https://github.com/eclipse/smarthome/issues/4302. It would be nice to have your feature request also in the issue. It would be even nicer if you could have a look on how an implementation could look like :-)

Cheers,
Henning

Hi Henning

Seems that the issue there is for things and not for items, so maybe I should open separate issue?

Note that the reason for this request is not filtering (as items do have filtering) but it is because of limited resources on embedded devices.

I will try to take a look on the code side but I it will take some time :-(

I had the same requirement a couple of times also and therefore agree it would make sense.
So I took this as an opportunity to experiment a little and turned it into a little PR.
How about something along the lines of #4517?
