You need to know about these smart kitchen gadgets

Connected countertop ovens like the Tovala Smart Oven were popular at this year's Smart Kitchen Summit. You can use the microwave-sized Tovala in two ways: As a standalone countertop oven that you can control with an app, or in conjunction with Tovala-delivered meals. The appliance will scan bar codes on meals the company sends you and cook the food accordingly.

The $1,500 June Intelligent Oven's release date has been pushed back to the end of 2016, so many Smart Kitchen Summit attendees were anxious to see this gadget. The countertop oven uses built-in cameras with face recognition technology to identify foods instead of faces and cook the food based on what it sees.

Anova entered the kitchen with its immersion circulator of the same name, a device that maintains the temperature of a water bath for sous vide cooking. Anova announced at the Smart Kitchen Summit that it will release a precision oven in summer 2017 that will sear, convection bake, steam cook, sous vide and connect to the brand's immersion circulator.

The Flatev raised nearly $136,200 during the product's fully funded Kickstarter campaign, so there's definitely a demand for a product that's essentially a Keurig for tortillas. But the creators estimate that the Flatev will cost between $400 and $600 when it becomes available for purchase in 2017 -- and that doesn't even include the price of the tortilla dough pods you have to buy.

The Hestan Cue smart system was one of the guided cooking products on display at the Smart Kitchen Summit. The Hestan Cue uses Bluetooth-connected cookware (reminiscent of the Pantelligent smart frying pan), an induction cooktop and a connected app to give you step-by-step recipe instructions.

The Cuciniale system, which just started a Kickstarter campaign this week, uses a connected temperature probe to communicate with an induction cooktop that adjusts its heat levels accordingly, similar to what we've seen with GE'sParagon Induction Cooktop. The Cuciniale app guides you step-by-step through recipes.

The Oliver was one of the most unique-looking products on display at the Smart Kitchen Summit. You select a recipe from the corresponding app, prepare the ingredients according to the recipe and place them in containers at the top of the device. The connected cooking machine then drops the ingredients into the main cavity based on the recipe you selected, and it cooks in that compartment.

The Cluck was one of the simplest devices at the Smart Kitchen Summit. You throw the orange, egg-shaped temperature sensor into a pot of water, and it will send you alerts via an app when your water is ready and boiling. Cluck's creators, who are running a crowdfunding campaign on Indiegogo, estimate that the device will retail for about $35.

The Alchema connected craft cider maker is another product that received full funding from Kickstarter campaign. You select a recipe from the Alchema app, add fruit, sugar, water and yeast to the device, and let the mixture ferment for a week or two. The product will sell for about $500.

One smart device, the Inirv React, is focused on bringing safety into the kitchen. You mount sensor above your cooktop and a special adapter to each of your oven knobs. If the sensor detects that a burner is on but no one is around, the adapters will automatically turn the burners off. The product will launch as a Kickstarter campaign in January 2017.
