Anova Culinary

Anova Culinary, registered as Anova Applied Electronics, Inc., began charging new users $1.99 per month to use its companion app in August 2024, converting a feature that had been free for ten years into a subscription.^[1] The company's Precision Oven routes all app commands through cloud servers with no option for local control, meaning a server shutdown or internet outage disables remote cooking features on hardware the consumer already owns.^[2] Anova is a subsidiary of Electrolux, which acquired the company for $250 million in February 2017.^[3]

• The app that controls Anova's sous vide cookers and ovens was free from 2014 to August 2024. New users now pay $1.99/month or $9.99/year for remote control and recipe access.^[1]
• The Precision Oven communicates exclusively through Anova's cloud servers via WebSocket connections. There is no local control option; if Anova's servers go offline, the app can't reach the oven.^[2][4]
• A firmware update on July 28, 2025 bricked approximately 145 Precision Oven units, rendering their displays unresponsive. Anova's workaround involved tin foil and tape.^[5]
• The Precision Oven 1.0 has a documented design flaw where the flex cable in the door hinge severs during normal use, disabling the touchscreen display. No recall has been issued.^[6]
• Anova settled a class action lawsuit for $500,000 over alleged violations of California's Song-Beverly Credit Card Act.^[7]

Anova was founded in 2013 in San Francisco by Stephen Svajian, Dr. Frank Wu, Jeff Wu, and Natalie Vaughn. The company originally manufactured temperature control products for scientific laboratories before pivoting to consumer kitchen appliances.^[3] In May 2014, Anova launched a Kickstarter campaign for the Precision Cooker, the first Bluetooth-connected sous vide device. The campaign raised $1,811,321 from 10,508 backers against a $100,000 goal.^[8]

Electrolux acquired Anova on February 6, 2017 for $250 million ($115 million in cash up front, with the remainder tied to financial performance targets). The acquisition was completed on April 4, 2017.^[3][9] Anova retained its brand identity and CEO Stephen Svajian continued to lead the company as a subsidiary.

In August 2020, Anova launched the Precision Oven, a countertop combination convection-steam oven, at $599.^[10] The Precision Oven 2.0 followed on November 5, 2024 at $1,199, adding an onboard camera and requiring a $1.99/month or $9.99/year subscription for recipe access.^[11]

Main article: Anova oven app subscription model

On August 15, 2024, CEO Stephen Svajian announced that the Anova app would move to a subscription model effective August 21, 2024. New users would pay $1.99 per month or $9.99 per year for remote control, status monitoring, and recipe access on all Anova connected devices, including sous vide cookers and ovens.^[12] Without a subscription, Anova's connected devices function as basic appliances without app connectivity.^[1]

Svajian justified the change by stating that "each connected cook costs us money," citing infrastructure expenses from "hundreds of millions" of connected cooking sessions.^[13] He did not disclose specific cost figures. The announcement generated 195 comments on Anova's blog post, the majority expressing dissatisfaction, and Engadget, Slashdot, and The Spoon covered the backlash.^[1][14][13]

Users who had created an Anova account before August 21, 2024 were grandfathered into free access. New buyers of any Anova connected device after that date must pay the subscription to use app features that were previously included.^[12]

The Anova Precision Oven routes all app-to-oven communication through Anova's cloud servers rather than using local protocols like Bluetooth or mDNS. Reverse engineering by Matt Colyer in February 2024 revealed that the oven's original API communicated via WebSocket at wss://app.oven.anovaculinary.io, with the app using Firebase and Algolia for its interface.^[2] The oven-to-cloud layer originally used Google Cloud IoT Core over MQTT, with certificate pinning that prevented independent traffic inspection.^[4]

When Google shut down Cloud IoT Core on August 16, 2023, Anova pushed a mandatory firmware update. Ovens that did not receive the update by that date lost all remote monitoring, app control, and future firmware update capability. Because the original firmware used hardcoded AWS hostnames rather than standard DNS, ovens that missed the update window were permanently severed from Anova's backend with no recovery path through the app.^[15] The migration moved the API endpoint to wss://devices.anovaculinary.io.^[15]

Local network control remains unavailable. A Homebridge plugin developer confirmed that the integration "does not locally connect to the oven" because "nobody has reverse-engineered a solution for that yet."^[15] The Home Assistant community's integration effort reached the same conclusion: the oven operates exclusively through Anova's cloud infrastructure.^[15]

In August 2024, alongside the subscription announcement, Anova stated it would remove app support for the original Precision Cooker models (including the Bluetooth and Bluetooth+Wi-Fi versions) beginning September 28, 2025. Affected users would retain basic manual controls but lose all app connectivity, remote monitoring, and smart features.^[1]

On November 21, 2024, Anova reversed the decision, announcing that it would "continue to support all versions of our products indefinitely." The company acknowledged that the original cookers, some over ten years old, run on "a separate, older infrastructure" requiring ongoing maintenance, but stated it was "a challenge we're ready to embrace."^[16]

The Precision Oven 1.0's touchscreen display is mounted in the door handle, connected to the oven body by a flex cable routed through the door hinge. Repeated opening and closing severs the cable, typically after approximately 18 months of use, causing complete display failure and making the oven unusable through its physical controls.^[6]

The defect is not isolated. Multiple users on the Anova community forums reported identical failures, with some experiencing it on two separate units. One user described it as "a poor design flaw." A firmware changelog entry noting support for "new oven handle components" suggests Anova revised the hardware in later production runs, but the company has not issued a recall or publicly acknowledged the defect as a design flaw.^[17][18]

DIY repair involves disassembling the door, locating the severed wires, and soldering them back together. The repair saves approximately $600 compared to purchasing a replacement oven.^[6]

On July 28, 2025, Anova pushed a firmware update that caused approximately 145 Precision Ovens to display a black screen on startup, rendering them non-functional. Anova pulled the update after discovering the problem.^[5]

The company's recovery method required owners to fashion a conductive strip from tin foil and tape, insert it into the oven to keep the touchscreen active during a three-hour overnight update window (1:00-4:00 AM local time), and verify the fix the following morning. Anova offered refunds to customers unwilling to attempt the workaround and committed to replacing any ovens that remained non-functional after the recovery attempt.^[5]

In Margaret McClure v. Anova Applied Electronics Inc., Case No. CGC-24-615351 (California Superior Court), the plaintiff alleged that Anova violated the Song-Beverly Credit Card Act by requiring customers to provide personally identifiable information when making credit card purchases on its website or app. Anova agreed to pay $500,000 to settle the class, which includes approximately 6,644 California residents who made credit card purchases on Anova's digital platforms between June 12, 2023 and June 12, 2024. Individual payouts are estimated at approximately $45. Anova also committed to implementing business practice changes for at least two years.^[7]
