Thanks. I have hue and nest with google home. My current Logitech buttons are getting tired (harmony 555 many years old) and seems to always need help to get activities working.The hub will work on it's own via a smartphone / PC app (which you will have to use to set it up anyway) and can be fully controlled that way, if you have Alexa or a google home it will also work via voice right down to changing channels on the google home after a recent update. However I would go for the remote as it makes it easier.
Some other things if you get the remote, it's fully compatible with Nest, Smartthings and hue and allows adjustment of these other products through the remotes touchscreen.
