Add a tile to a device?

Ive been searching for this to no luck, maybe some else can point me into the right direction.

I would like to add a tile to a device if possible. Here is what I am trying to accomplish.

I have set up CoRE to turn on and turn off my dehumidifier VIA a appliance module in the basement based off of the humidity level of my NEST in the basement, not the dehumidifier it self. The NEST is on the other side of the room and I found it to be fairly accurate to a hygrometer compared to the dehumidifier itself.

What I want to do is be able to go to the appliance device in the app and have it display the humidity from my nest. This way I can manually turn on/off, monitor energy use, and view the humidity all on one page.

Is this possible???

Thanks for the help and insight you can provide!

You will need a SmartApp in the middle to relay to the dehumidifier device. The SmartApp would subscribe to the events of the Nest and send those events to the dehumidifier device for display in a tile.

Hopefully that answers your question?
