vscode extension shows error wrongly with temperature variable in rules

[Spiev]

Good morning everyone!

I use a "virtual" temperature item to set a target temperature with the type "number:temperature". In the rules I use this item to compare the "target" with the "current" temperature. If target is higher, I switch on the powerplug of the electric heater.

The current temperature comes from an LoraWan device. The powerplug is an zigbee device from ikea.

Everything works fine. Except that vscode extension shows me an error. In my unterstanding, this is wrong. vscode extension error:
[{
"resource": "/c:/repo/openHAB/rules/noahheater.rules",
"owner": "generated_diagnostic_collection_name#0",
"code": "org.eclipse.xtext.xbase.validation.IssueCodes.incompatible_types",
