I have some devices that work with GH and some that work with HK. I was going to have both apps open at the same time, but GH doesn’t support multitasking on the iPad. So that led me to try to find an app that combines the two platforms into one view, but I haven’t been able to. Any suggestions?
Hame assistant is the best option out there. I have Google home, homekit, universal devices, zwave,zigbee and MyQ just to name a few. You can get HA yellow and be up and running in a half hour.
