Step 7:

Lastly, I enabled the product to publish an event every time that the diffuser turned on.  My intent was to also publish the volume of the fluid as well and create a graph in Google sheets showing a trend line of this data, but since the fluid levels will never change (because it is only an LED and not a diffusor), I decided to try to add this functionality in an upcoming project.  Also, to do this, it looks like I need to use some Javascript JSON commands, which I am not familiar with, but I am willing to try in the coming weeks.

Also, I used IFTTT to log every instance of the diffuser turning on into a Google sheet document.  Attached is a couple hours worth of this data.
