Translate "XXX" to "0" if numerical value is expectet

[Christoph Wempe]

I'm reading some values of my fathers photo-voltaic generator.

I'm doing this via HTTP-binding of the web interface.

But when it's dark the web interface shows "XXX" for the current value.

Is there a way to tell openhab to interpret this as "0"?

The monitoring-tool "mrtg" has an option calles "unknown as zero" for cases like this.

Hi Christoph,

which kind of transformation are you using? When using XSLT you could replace values ...

Just HTTP with RegEx:

Number Solar_Aktuell "aktuell [%.1f W]" <firstfloor> (gAttic) { http="<[http://user:password @192.168.0.27/index.fhtml:60000:REGEX(.*?aktuell</td>.*?  (.*?)</td>.*)]" }

hmmm ... which web interface are you talking about? Classic UI? I am wondering that XXX should because the type is "Number" and "XXX" is no valid Number at all. In that cases "-" should be shown :-/

Could you send some log entries around the State update?

Maybe I didn't discribed the problem proper. :)

I meant the web interface of the solar-device.

It shows "XXX".

When opening GreenT (openHAB-web interface) or HABdroid I get this log:

22:30:19.813 ERROR o.o.u.i.i.ItemUIRegistryImpl[:396] - Cannot retrieve item 'Solar_aktuell' for widget org.openhab.model.sitemap.Chart

solar_hm.sitemap

sitemap home label="Solar HM"
{
Frame label="Solar" {
Text item=Solar_aktuell {
Frame {
Text item=Solar_aktuell
Text  item=Solar_Tagesenergie
Text  item=Solar_Gesamt
}
Frame {
Chart item=gSolar_Energie period=d refresh=300000
Chart item=Solar_aktuell period=d refresh=300000
}
}
}
}

Maybe this problem doesn't exist tomorrow after openHAD will get the first valid values for this item.

I think we will wait and see what happens tomorrow. :)

My bad!

I just realized I misspeled the item-name in the sitemap. (case-sensitive: "Solar_aktuell" vs. "Solar_Aktuell")

Everythings works fine now.

Thanks anyway. :)
