Will HA detect all the sensors/switches on Google Home

Hi GUys,

Noob here. If I have switches and sensors that are not integrated with HA, but has integration with Google home, will they show up on HA?

Also does HA detect all wifi devices in the area or does the switch/sensor manufacturer need to have integrated with HA?

As far as I know: no

No they won’t. The Google Home API only works the other way around, you can expose entities from home assistant to Google Home. Nothing home assistants devs can do about that. It’s the way Google designed it.
