Thanks for the detailed reply. I also found their little video fascinating in the realm of "cigars," as it shows that one of the real big (high end) appliance guys out there is thinking about it ... and if they are thinking about it, then hopefully the idea will start to permeate down through the more moderately priced people.
Heretofore, I've only seen thoughtful consideration for fine temperature and humidity control in the world of laboratory research (aside from your work). Attached is a fine example. To say these units are expensive is an understatement.
I have a question (s), however: Since your medium of interest (cigars) have a relatively long hysteresis (rather than, say, a cell culture for which the attached unit is designed whose rate of change to the environment can be very, very fast [functionally instantaneous]), why do you maintain such a high sample solution and cycle rate? Going by the RH waveform inflections, I see roughly 10 minute cycle periods? (eyeballing) Is this a function of your sampling resolution or a desired performance based on a return-to-setpoint time target? Obviously bounce exists in all measureable parameters as a function of the resolution of the data and performance of the "closed" system, but why not stretch out the resolution as a function of the hysteresis of the medium? I know you mentioned in your videos that your rate of mechanical failure has been zero, so I suppose it is a moot point, but I am curious.
