Hey Will,
Welcome to the Cayenne community. Glad you are liking Cayenne so far. We’re working on some very cool features to make Cayenne even better.
To your point, one of the things we’re working on is the ability for you to bring on whatever sensor you’d like and display it in Cayenne. We’ll be discussing it with the community here: Online Meetup - 03/24/16 12pm - 1pm PDT - #19 by mac_ha .
Curious, what temp/humidity sensor?
