I have been an Amazon Echo user for a while - pretty much as soon as you could get one. We've actually had two plus an Echo touch. But, when Google Home was announced I immediately switched. I switched us because of the ability to have all of the Google Home devices synced and playing the same audio everywhere in the house. I bought four Google Homes and a Google Cast Audio (if that's what it's called) to connect to my stereo in the garage. The future sounded bright and I was pretty amped to be able to listen to music throughout the house.
Until I couldn't.
Sometimes I can; sometimes all of the devices show up as part of the group I defined and named "The House" and when they all do and I tell one Google Home to play music on "the House" it works. It's great. Sure, the speakers on each aren't all that good; specifically the bass which sounds a lot weaker than the full sized Echo. However, the sound is good enough and I didn't have to run wires or buy an expensive Sonos system to get wireless audio throughout my house. So, for the most part I'm pretty happy.
But, sometimes, the group only shows a couple of the Home devices as part of the group. I don't know why. Maybe it has to do with the mesh network (Luma) we have and maybe sometimes the Luma devices aren't working? Or maybe the Home devices have trouble realizing their on the same network when they are on a mesh network?
Whatever it is it's pretty disappointing because it happens too often.
Another problem I run into is that I connected all of the Home devices to my account. But if I'm in the garage casting music and my wife is in the kitchen and she tries to cast some other music - my music is shut off because I can't use my account in more than one place at a time. There is no obvious easy way to disconnect some of the Home devices from my account. It appears I have to reset them to factory settings, set them back up, then attach them to different accounts. So, in order for my family to use the various Home devices as separate music players I have to assign each device to a different account in the family. I'm already paying for the Google Music family account so then it should be fine. But it's still an annoying limitation. We're all in the same place on the same network it shouldn't be this difficult to have them work independently when we want. Or, at least, Google should warn you when you're setting them up that this could be an issue and advise you to use different accounts for each Google Home device.
Another big problem is the calendar integration. My wife and I each have our own calendars plus we have a shared "family" calendar. It makes it a lot easier to filter our events when we need to from within the Google Calendar app/webpage. But from within the Google Home device we can only access the link accounts primary calendar. And, as far as I know, we can't add calendar events from it.
Oh, and we can't "like" a song from the Home device either. I am pretty sure I could do that from day one on the Echo. Alexa had a lot of problems with her overall music selection on Amazon prime music via the Echo - but at least it could "Like" a song. I don't understand how this simple feature didn't make it into the earliest version of Google Home. I suspect a lot of people got these things for music as their primary use.
The wake word "Ok Google" is also shitty. I mean, it's a fine phrase, but if you use Android your phone probably responds to the same wake word. The wake word needs to be customizable. I'eve had the Google Home commercial wake up my Google Home device before. I don't need that kind of crap.
I like the Home devices when they work (playing music as a group around my house) but for the time being I just can't recommend them to anyone else. They are too limited on features and don't seem to be getting any kind of regular monthly updates. If they are then they aren't advertising the updates well. Amazon sends me an email regularly telling me about new things Echo can do (though I hate the "skill" integration of Echo and the need to manually activate skills; at least they are expanding the capabilities of the device). Google just rushed out their thing to be in the market before Christmas and then seemed to pretend like it's sufficient.
I hope it gets better. But, in the mean time I have to create a new google account so that I have five different accounts in my Google Family Music subscription (since I can't invite a not "gmail.com" google address) and so each device can be on it's own account. Hopefully the group play feature will still work when they are all on different accounts.
I guess I could have named this post "Google Home - The Bad"
