I installed this app to improve automation of my home system, which is from Wiser Heat, by linking it to the presence sensing in Google Home. I can link Google Home to Wiser OK, and it will perform basic actions like setting a socket off or on, very fast in fact. But there it ended. The Home app is not intuitive to set up, and the online documentation is poor, in my case it it referred to menu options which didn't appear (they were not just greyed-out, they didn't appear at all). Somehow I stumbled upon the option to create a Nest network and hey presto!, the presence sensing options appeared (and other options rearranged themselves, I think). However, for some reason the dialogue for creating actions from presence sensing ("Home") is different from the dialogue for creating actions from voice commands ("I'm Home"), and it's very much more limited - it offers to control a couple of specfic devices, but not to adjust thermostat settings or to switch the Wiser away mode off or on even though that's a standard voice command.
