No edit summary
I tried to shorten the article and make it more to the point. Hopefully more people can continue to work on it. Thousands of Sengled consumers have been left without the service they were promised at purchase, and all without explanation.

Overview
Sengled is a Chinese smart lighting manufacturer who promises affordable, Alexa- and Google-compatible smart bulbs. However, systemic issues with their business model, specifically, dependence on proprietary cloud services, has led to widespread consumer backlash. The Sengled app was removed from the Alexa app when Sengled's cloud servers repeatedly offline without a statement or comment from the company. Soon after companies like Home Depot Canada stopped offering the sale of the device on their websites. As of August 2, 2025 there has been no comment from the company and even control of the bulbs through their own app has stopped working.


Sengled, a Chinese smart lighting manufacturer, entered the global market promising affordable, Alexa- and Google-compatible smart bulbs. However, systemic issues with their business model — specifically, dependence on proprietary cloud services — have led to widespread consumer backlash. Recent events highlight the inherent risks consumers face when purchasing cloud-dependent devices.
Consumer Impact Summary


The Cloud Dependency Problem
Sengled’s smart bulbs can no longer connect with Alexa and Alexa has removed the Sengled app from its platform. There has been no statement from the company on the problem. The Alexa Skills Store still lists the Sengled skill as unavailable as of July 2025. (Amazon Alexa Skills Store)


Sengled’s smart bulbs require constant connection to Sengled’s proprietary cloud servers to function with third-party platforms like Amazon Alexa and Google Home. Unlike Philips Hue or LIFX, which offer local network control options, Sengled bulbs rely on their cloud infrastructure for even basic commands. (Sengled USA Support)
This removal means users no longer have voice control functionality. Sengled has issued no formal public explanation and has failed to communicate with their customer base.


In June 2024, multiple tech news outlets reported that Sengled’s Alexa Skill — the service enabling Alexa control — had been removed from the Amazon Alexa Skills Store. (TechHive Report, June 2024)
As for August 2, 2025 the Sengled app is no longer working and the Sengled Smart Bulbs cannot even be controlled from the company's own application. Again no statement has been released regarding the state of Sengled cloud servers.  
 
This removal resulted in users losing voice control functionality overnight. Despite the severity, Sengled issued no formal public explanation and failed to communicate effectively with their customer base. The Alexa Skills Store still lists the Sengled skill as unavailable as of July 2025. (Amazon Alexa Skills Store)

Systemic Industry Issue: Cloud Reliance
Sengled’s case underscores a broader systemic issue within the smart home industry — the risks of over-reliance on proprietary cloud services. When companies fail to provide local control options or open APIs, consumers become vulnerable to:
Sudden feature loss if cloud services are altered or terminated
Forced obsolescence due to corporate decisions unrelated to hardware performance


Lack of consumer recourse when service disruptions occur
Lack of consumer recourse when service disruptions occur
These risks have been highlighted by consumer advocacy groups such as the Electronic Frontier Foundation (EFF), which warned about cloud-connected device failures and consumer rights. (EFF Report on IoT Risks, 2023)


Conclusion
Conclusion


Sengled’s failure to maintain its Alexa integration — without warning or effective customer communication — reflects a systemic problem in the smart home market: cloud dependency without fallback options. This incident highlights the need for stronger consumer protections, transparent product lifecycles, and open standards in the IoT industry.
