So, I’ve been trying to connect PiFace Digital 1 to Cayenne app but the button is grey. Why? Does cayenne even support digital 2. Does digital 1 have like the same chipset as the digital 2?
Sorry, i dont have that much experience of this… Im 14 years old 
Hi @blube63.eq,
No need to apologize, we’re here to help! 
We do support both the PiFace Digital 1 and 2 but we are aware there may be issues with our implementation. Can you take a quick screenshot to show me which button is showing as grey?
