With the Eco I will need to monitor the Humidity. I plan on putting a Thermometer/Hygrometer inside the unit. I also plan on having 24 eggs inside, at least to start. Should I have it sitting on top of the eggs? Or is there a good way of attaching the unit to the inside with tape or something? I am also worried that if it is just sitting there, it will slide back and forth when eggs/unit is being turned. How are all of you current Eco users securing your gauges inside of the unit? Thanks.
