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. But if your bulbs were Sengled’s Wi-Fi ones, you’re out of luck. Devices that work over Zigbee, Z-Wave, BLE and BLE Mesh, and local Wi-Fi, also offer local control. Matter Matter is a smart home interoperability standard designed to provide a common language for connected devices to communicate locally in your home without relying on a cloud connection.
