After repeatedly leaving customers without smart control of their lights, Sengled has been booted from Amazon’s Works With Alexa program. As first reported by TechHive, beginning August 1st, Sengled’s Alexa skill for controlling its line of LED lights, plugs, switches, and sensors with your voice and routines is no longer available.

In a statement to The Verge explaining the decision, Amazon spokesperson Lauren Raemhild said, “We hold a high bar for the Alexa experience. Sengled has experienced a series of prolonged outages over the past few months that have not been resolved, preventing customers from being able to use Sengled’s Alexa skill to control their light bulbs.”

The future doesn’t look bright for Sengled, which has been silent since the problems started appearing earlier this summer. There appears to have been no communication to customers from the company (Amazon did reach out to its customers about the outages), and no indication of these issues on its website. Repeated attempts by The Verge to contact Sengled have been met with no response.

There is some good news. If you own Sengled bulbs that use Zigbee, BLE Mesh, or Matter, rather than Wi-Fi, they can still work with Alexa by bypassing Sengled’s spotty servers and connecting to a compatible Echo speaker or Eero Wi-Fi router (this may require setting them up again). Another option is to connect Zigbee bulbs to third-party platform hubs that support the protocol, such as Home Assistant, Hubitat, or the Aeotec SmartThings hub.

But if your bulbs were Sengled’s Wi-Fi ones, you’re out of luck. These won’t connect to Alexa, although they will still work with Sengled’s app, for as long as Sengled’s servers are still running. Users have started reporting problems there, too. All of which goes to show that relying on cloud services to turn your lights on is a fragile solution.

This is a story we’ve seen too often in the smart home. Just last month, Belkin shuttered its WeMo smart home business, and the smart home graveyard is littered with other examples: iHome, Revolv, Staples Connect, Lowes’ Iris, Best Buy’s Insignia, and more.

A common thread with these shutdowns is that the products relied on cloud servers. At one time, it was easier and less expensive for a company to develop a cloud-based controller than a local system, as they don’t require a hub or bridge and can be simpler to set up and use.

However, companies have to maintain those servers, as well as API connections to smart home platforms and voice assistants like Alexa and Google Assistant, which can be costly and resource-intensive. When the business model no longer pans out, history shows us that if they can’t sell it, companies just shut it down.

This brings me to my best piece of advice to anyone buying a smart home device today, especially something as integral as lighting: make sure it has the option of local control. That way, if the company goes under or stops providing the service you signed up for, then your device will still keep working (in some fashion). Plus, locally controlled devices tend to be faster, as they don’t have to wait for a response from a server.

As noted, some Sengled bulbs don’t rely on a cloud connection and instead can work locally in your home. Thanks to a connection via local protocols like Apple’s HomeKit or Zigbee, some products from those companies listed above also still work, even though their servers are gone.

That’s one of the reasons why the new Matter standard is so crucial to the smart home. While it has had its problems, Matter is built on the foundations of HomeKit, Zigbee, and other technologies. It’s an entirely local protocol, communicating to a Matter controller (hub) in your home, not to a company’s cloud.

While Matter ecosystems such as Apple Home, Google Home, Amazon Alexa, and Home Assistant can connect to the cloud to give control when you’re away from home and enable other features like voice assistants, that’s a layer on top of Matter. If a device like a smart bulb supports Matter, either over Wi-Fi or Thread, you don’t need the internet to turn on the lights. And, if the manufacturer’s server dies, your device won’t.

Matter isn’t the only option here. Devices that work over Zigbee, Z-Wave, BLE and BLE Mesh, and local Wi-Fi, also offer local control. But the standardization of Matter, its wide industry support, and its use of non-proprietary IP-based protocols Matter and Thread all broaden its overall compatibility and should make it more futureproof.

The situation with Sengled is just the latest reminder that for a truly reliable smart home, look for local control. While the cloud offers benefits, it should be part of your solution for a smarter home, not the only one.
