I trying to create a widget that has bigger font for temp sensors, so I can see the data from longer distance.

I have come so far so that I can choose devices, but I can’t get the values from the devices. I have tried many things. But I think I don’t understand some basics for the Homey SDK.

Do I need permissions for that (homey:manager:api)? If I add that then I can’t start the app with the widget.

```auto
× App did not validate against level `debug`:
× Error: Invalid permission: homey:manager:devices

```
