Amazon expands Matter smart home support to older Echo speakers

Amazon's Matter support is reaching some of its older speakers. A new Alexa update turns the second-generation Echo, Echo Dot and Echo Plus into Matter controllers — you don't have to replace the old speaker in the basement just to use newer smart home devices. The fourth-generation Echo, meanwhile, can serve as a Thread border router to help you add Matter-capable Thread devices. You won't have to use Android to set up Matter gear, either, as iOS is now an option.
