openHAB 4.2 Milestone discussion

Since OH4.2M4

I followed the tutorial Displaying the weather forecast with charts (OpenWeatherMap) - #5 by florian-h05

created a thing

Bridge openweathermap:weather-api:api "OpenWeatherMap Account" [apiVersion="3.0", apikey="apikey", language="de"] {
    Thing weather-and-forecast smarthome "Smarthome Weather And Forecast" [location="mylocationis hidden"]
}

than created items

Number:Temperature    OneCall_Forecast_Hourly_Temperature                             "Temperatur [%.1f °C]"                     <temperature>  (gOWM_TimeSeries)  {channel="openweathermap:weather-and-forecast:api:smarthome:forecastHourly#temperature"}

but see in the ui unlinked item (see attached) I than thought to change it to a ui created thing and changed the item to

Number:Temperature    OneCall_Forecast_Hourly_Temperature                             "Temperatur [%.1f °C]"                     <temperature>  (gOWM_TimeSeries)  {channel="openweathermap:weather-and-forecast:456c607133:f56a6adab0:forecastHourly#temperature"}

Now I see to unlinked channels see attached pictures…
the old link is only deleted if i clean the cache.


How can I configure the openweather thing correctly?
