Hi,

When I try to install the “Can I Wear Shorts Today” app on homey, I get the message “[incompatible\_app\_version]”.  
My version is 4.2.0.  
I would love this app to work, because I could use the data to auto control the sunblinds.

Thanks,

Dwayne

Also I already tried rebooting and updating the firmware.

The app has not been updated in 8 months and has stopped working. Alternatively, you can use this app:

> **[OpenUV](https://homey.app/de-de/app/io.openuv/OpenUV/)**
>
> Provides Homey with UV index forecast

Thank you undertaker for your input,

I installed the OpenUV app but when creating a card, I can only choose “UV index change”, but cannot set how much. I would like to lower the blinds when the sun shines to bright.
