Z-rain delete

Hi,

I have bought a Popp Z-rain. I installed the 2.06 version of the app and I am on homey 2.1.1.

Because I didn’t get any readings from the z-rain I deleted the app and installed it again. Now I can’t install the z-rain again. It says allready installed or cannot find a device.

is there any soluties for that? OR is there another way to use this rainmeter?

Otherwise I payed a lot of money for a device I can’t use.
