I don’t have a Google Home so Home Control doesn’t show up in the Home app on my Android phone (Nexus 6p running Nougat 7.1.2). However I discovered you can add ISY through the Home Control in the Google Assistant settings menu.
I’ve had Amazon Echo integration running since it was first released. Although I’ve only just started to use Google Assistant Home Control it rocks compared to Alexa. Alexa is very literal so I needed to add several synonyms in the ISY portal to deal with things like “light” or “lights”. Assistant on the other hand can handle much more imprecise input as well as dynamically grouping devices based on common words. I have several different sconces (living room, bedroom, etc) and when I give the command to turn on the sconces is turns them all on. Also as previously reported response time is very fast.
I have the Google Assistant SDK running on a Raspberry Pi. Haven’t been using it since I originally set it up but now that ISY integration is working I’m going to go back and hopefully start using it for home control rather than AlexaPi. I’m also thinking about buying a Google Home to replace at least one of my Echos.
Really appreciate the work on this and ongoing investment by the UD folks.
