After installing a Logitech Harmony hub and linking it to Alexa I’ve found myself talking to my TV.
It switches the TV on and off and starts up services like Roku (although it did start playing “We Will Rock You” by Queen the first time I tried…). It also pauses and restart the telly on DVR and OTT.
This means that we can use Alexa (or can just use our mobiles or iPads) instead of five remotes and around twelve apps. Magic!
