Widget for Climate

**Is your feature request related to a problem? Please describe.**
Currently I'm frustrated not to modify the temperature state of my thermostat via widget. The state of the Thermostat could be accessed via Text-Widget.

**Describe the solution you'd like**
Show something like the slider in the [Webview](https://community-assets.home-assistant.io/original/4X/0/9/d/09d3a79dff1d4082d3eefa27766dbb958fa51f53.png):

**Describe alternatives you've considered, if any**
Trying to build a custom App wich shows the html content as widget, but google has removed this feature. It would be possible to create a custom app and add a widget there. This isn't a nice flow and wouldn't be beneficial for broader audience.

**Additional context**
Currently some fritzbox dect 301 is used to create the climate zone
