/* now id like to create a method that allows users to just return say the humidity for a cube as i think it might be useful to retriev
 	 one thing so ive written another one where I pass in a device id run the method above and then filter the results
 	 does this seem right to you or should the method just accept the results and then filter so they user would have to run 
 	 get current reads and then pass them into another call?
 	 The reason I ask this is because then the method only has one responsibility and thats to filter the results it doenst need to worry about 
 	 calling the above method first then filtering.
