Hello. In Openhab 4, I have the following item configuration: Number Windgeschwindigkeit "Windgeschwindigkeit [%1.f km/h]" { channel="knx:device:bridge:sensors:Windgeschwindigkeit"[profile="transform:JS", toItemScript="ms_to_kmhval.js", toHandlerScript="kmh_to_msval.js"] } The intent is to us…

knx Binding is unit aware since OH4.0 (maybe since OH3.4), so it’s way easier to do it the UoM way. Type number : windspeed "Windgeschwindigkeit" [ ga="9.005:1/2/3" ] // which DPT is used? Type number : windspeed "Windgeschwindigkeit" [ ga="14.065:1/2/3" ] // which DPT is used? The Item: Number:…

I’m not sure if that answers his question about why toItemScript doesn’t seem to work. Setting aside for the moment whether to use units vs transforms. I have a regular Number type (no units) from a binding holding a temperature value that I want to convert from C to F. Number OutTempX “Temperat…

Given the official documentation [image] Fine Offset Weather Station - Bindings This binding is for weather stations manufactured by Fine Offset. the channels do use QuantityType, so please don’t mess with JavaScript but use UoM Number:Temperature OutTempX "…

Thanks a lot Udo, this looks great! I now updated this to: Type number : Windgeschwindigkeit "Windgeschwindigkeit" [ ga="9.005:0/0/20" ] and: Number:Speed Windgeschwindigkeit "Windgeschwindigkeit" { channel="knx:device:bridge:sensors:Windgeschwindigkeit", unit="m/s" , stateDescriptio…

[image] ericbodden: By the way: what is this weird syntax with “” in the stateDescription? Why two quotation marks? That’s an error and should be corrected. The forum likes to make our posts “pretty” and it replaces normal double quotes with these fancy reversy quotes. Because @billfor is u…

[image] ericbodden: By the way: what is this weird syntax with “” in the stateDescription? Why two quotation marks? In fact, you could setup a state Description, too (but it’s not used…) You can see it through the API Explorer: { "link": "<some link to an item>", "state": "22 °C", "sta…

I am even more confused now. So the double quotes are correct after all?

Well, at least for now you have to set the empty string when configuring the stateDescription pattern (openHAB states an error when not using the quotes). Number:Temperature OutTempX "Temperature" { channel="...", unit="°C", stateDescription=[pattern="%.1f °C"] } // openHAB will mark that as an con…

Okay the syntax looks alright because in the UI it now looks like this: [image] Yet, the item still shows UNDEF: [image] If I remove the stateDescription part then it correctly shows the m/s value.

That’s strange behavior, works for me (at least when sending some values directly to the Item. I do not have a knx wind sensor. [Screenshot 2023-12-10 014346]
