UPDATE 2018-11-12: Please note that this post is outdated. We have already added a post for the new blue Harmony Service in Google Home: Logitech Harmony and Google Home: New Setup and Voice Commands additionally to the old retired red Harmony Service in Google Home: Logitech Harmony and Google Assistant: (Retired) Setup and Voice Commands
UPDATE 2018-11-08: The integration looks much better now. I’ll publish an updated setup & voice command post until tomorrow (Friday) evening, so you can enjoy the new features over the weekend! We have waited for so long and there was already a half finished, lengthy post here, on how to update to the new blue Logitech Harmony Service on Google Home. During 2 days of testing some stranger things happened and I decided to scratch all and write this instead: My old Google Home routines for the old (red) Harmony Action were removed, without asking … Ok, let’s assume we don’t need them anymore. Oh, now I can’t even switch back? In a Google Home test setup with a Chromecast (something you might have in your living room), I ended up with randomly controlling the TV via Harmony (rarely) or more often YouTube on Chromecast with variations of the favourite channel commands. Today I reduced the test setup to only 1 Google Home and Harmony and here’s why I still cannot recommend it: Play some music (ok, playing music on Google Home) Stop (ok, stopping playback on Google Home) Turn on TV (ok, turns on TV Harmony activity) Turn off TV (nice, turns off TV Harmony activity) Play some music “Sorry, I can’t do that yet”
(After 1 hour) Play some music “Sorry, I can’t do that yet”
You’d need to unlink the blue Harmony service (or factory reset your Google Home device) to be able to play some music on this Google Home device again. Same applies for Volume Up/Down commands which you’d like to execute on the Google Home.
One might say: Well, let’s just add the name of the Google Home device to the command and voila, it works. Yes, but you don’t want to do that with the Google Home device you are obviously talking to. With all the complexity in the background, I believe this bug should be fixed first and not obfuscated with more explicit commands. Another problem area occurs with Chromecasts. Google loves to understand Youtube commands, so if you have a Chromecast around, it will most likely switch to playback from Youtube on there, rather than switching to your favourite channel via Harmony. With that, Harmony loses voice focus and commands which worked before on Harmony are executed on Chromecast (or not at all). Last but not least, I would not like to recommend workarounds with routines for this integration, as they obviously could get removed without asking us. Stay tuned for an update and hopefully better news! And please share your experience!
