Interesting concept - I have heard of grease "dose" devices before, AvE on YouTube takes one apart in this video: https://www.youtube.com/watch?v=ydhndNX_8KI

It's effectively an unattended, disposable piston that uses an electronic timer to periodically generate gases to push the grease out. Everything is calibrated so that it dispenses approximately the right amount over the right time period. For machines that can use one of these, I wonder if there is room for integration with the GreaseBoss RFID tags and tracking system.
