I havent had the chance to have a play with HomeyInk myself yet. But I dont see why not :
If you check out the apps code https://github.com/athombv/homey.ink/blob/master/app/js/homey.ink.app.js
And based upon the webAPI - which is what the groups App (which groups sensor data) is using :
https://developer.athom.com/docs/api/HomeyAPI.ManagerDevices.html
Especially considering you know the ID of the device you want should be easy :
Devices.getDevice({
id: id
})
As I mentioned I haven’t played with this myself yet - but have fun @Captaingreenfield - also remember you will want to place a capability listener to track changes in the sensor 
Also great little project for someone new to coding
