I have these values for temperature, humidity and lux in my Yubii app.

The values shown for temperature and humidity come from my sitting room. There is no value in the Yubii app for lux, but there is a lux device in my sitting room. 
 

How do I setup these values to show up in the Yubii app?

Did you configure the main sensors in the general settings?

I would expect something there. But nothing in the general settings. 
 

Ah, found it. In the device setting and the main tab. There was a lux sensor configured with an empty battery. Thanks.
