Consumer impact summary

Freedom

Through the app, users can delete their account by pressing the "close account" button, which will warn that Wemos cannot be controlled through the app once account data is deleted. The devices can also work by only using the Apple Home app, which does not require a Wemo account to set up.

Privacy

Since late 2023, the privacy policy of Belkin and Wemo have merged, sharing the same terms with each other. The data collected on users includes account information such as email and password, device information, first and third-party cookies, age, location, and IP address.[1] Belkin shares this info with marketing partners unless the user opts-out.[2] Users are allowed to make requests to access, withdraw consent, object, and delete most of the information Belkin has collected on them.[3] Belkin states they may need to hold onto information for "Defending Belkin against legal claims" or "Needing to respond to customer complaints and queries".[4]

Business model

The business model of Wemo is to sell smart home devices without the user paying for a subscription service. Although this may seem like a pro-consumer move, the Wemo experience has been diminished due to the lack of income streams. According to the App Store, the app once had a 3-year window without updates, which lasted between 23 February 2021 and 28 May 2024 (the current version as of 24 February 2025).[5]

Market control

Market control of Wemo has been decreasing over the years, as Wemo is only selling three devices,[6] down from nine the year prior.[7]

Incidents

Security vulnerabilities (2013—2023)

On 5 November 2013, Wemo updated its API to prevent future XML injection attacks.[8]

On 16 May 2023, multiple websites reported a Sternum study regarding a buffer overflow vulnerability in the Wemo Mini Smart Plug V2.[9] The study mentions the device could be exploited through a program called pyWemo[10] and potentially through cloud controls.[11] In their official response, Wemo stated "we believe that bad actors cannot exploit this vulnerability unless they have access to the user's local network",[12] and "We discontinued the Wemo Mini Smart Plug V2 (F7C063) in 2020"[13] despite not making this information publicly available prior. During this report, the Wemo app hadn't been updated in two years, with the most recent update being on February 23, 2021, as previously mentioned.[5]

Connection issues (2018—2026)

Since 2018, there have been reports of Wemo devices losing connection to networks frequently.[14] This has been the case for dimmers,[15] plugs,[16] and switches.[17] Device rules created through the Wemo app have also been described as unreliable.[18] In some cases, the Wemo cloud becomes offline, with users being led to 404 pages.[19] Reports of Amazon Alexa and Google home integrations not working for periods of time are also common.[20] Users have reported the devices only working with Apple Homekit[21], which can be inconvenient for users without Apple accounts or compatible devices.

DNS activity (2024)

Some users of Wemo have noticed their switches connect to multiple unrelated domains, such as to CNN and Fastly.[22] Other reports mention each Wemo device making 160,000+ DNS requests in a 24-hour timeframe.[23]

Discontinuation of cloud service (2026)

Main article: Wemo discontinuation of service
List of affected products from the discontinuation of cloud services

On 10 July 2025, Wemo users were e-mailed regarding the future state of the Wemo cloud services, including voice assistant and app support.[24] Devices that weren't designed for Apple HomeKit integration would cease to function after January 31, 2026.[25] This caused frustration for users who had non-Homekit Wemo devices because without software like Home Assistant, the devices cannot be used.[26]
