Your worring to much about the temp, I couldn't even tell you what temp my inc is right now, anywhere from 28 - 32 is fine and it can vary a bit each way without any hassle. The main thing is to watch for spikes and massive drops, ie un-natural temp changes.. Naturally the eggs would have some varience in temperature. Also something that people don't seem to talk about much is the heating the female has been kept at before and during being gravid, this has a dramatic impact on the health of the hatchlings, if the female has poor calcium levels, then the hatchlings won't form properly and fail to hatch.. Moisture is more important imo than heating (as long as it's within reason). Any thermostat can successfully run an incubator if it's set out correctly. The incubator should be kept in a cold place to prevent external temps from effecting the internal temps, and also the egg temp is usually a few degrees cooler than the average ambient temp of the incubator, so to incubate eggs at 31 deg, you may have to keep your inc at 33, use a lazer temp gun to monitor the egg surface temp, never trust a single digital thermometer either, I have 2 digital external thermometers that measure max highs and lows within the inc (and egg box) as well as a two traditional bulb type thermometers inside the inc... my inc varies by about 2 to 3 degrees throught the year.
