Combi-ovens are predominantly equipment that belongs in commercial kitchens, but nowadays, there are a few options (still not very many though) that can actually fit on a home kitchen countertop. The two notable ones are the Cuisinart steam oven (~$250-300) and the Anova Precision Oven (~$700); these are the low and high ends of the price range.
Did you miss a zero? Because all home combi-ovens I've seen in Germany are nearly 10x that price range. Granted, those aren't countertop but regular home oven form factor devices. They're explicitly for domestic kitchens though.
Correct. Although I am incredibly tempted to order a full sized shitty commercial one from China and hack on it.
All that goes on there is an evaporating tray of water and wet bulb temperature sensors (finicky to measure accurately). Imagine an environment similar to a dishwasher or rather, a sauna, where you play not just with the temperature but also the humidity by controlling the steam bath.
The Chinese commercial ones I am referring to use a fill valve with a float (not dissimilar to a toilet tank) to replenish the water from the evaporating tray found at the bottom of the oven. So might get away with an analog circuit.. I digress..
Instead of keeping your food in a plastic bag and recirculating the water through a heating element to keep the temperature you are just constantly boiling water and releasing steam so the entire oven cavity settles at an exact temperature AND humidity level. Hope I didn't bungle that explanation too much.
Anyway GM probably has super fancy home ovens of this nature for $10,000 a premium home gamer version of the sort of thing restaurants/fancy-hotels use. The pros simply front load food trays into them like this: https://www.youtube.com/watch?v=3cfll7tUcuA

The Anova thing is basically a tiny toy version of that.
