A:Answer It works with the Logitech Harmony Hub the same way a Google Home, Google Home Mini or Google Home Max would - that is to say, there are a variety of built-in commands once the Hub is paired with Assistant, as well as the possibility to create more complex, custom commands via Assistant"s Routines and apps like IFTTT;.
I currently use the speaker in conjunction with the Harmony Hub for Voice Control actions such as 'Turn on the TV and AV Receiver, set the Input to the HTPC, and dim the lights', 'Turn on the Xbox, set the input to the Xbox, and set volume to 50%', etc. Essentially, it allows you to control the Hub by voice, as well as to integrate commands to multiple Google Assistant-compatible IoT devices (like Philips Hue lights, etc) in a single command.
