#iot

I am a longtime Merlin user and have lurked the board for what seems like ages. I've never had to post before because like every tech savvy guru, I know that my problems are not unique. Someone... at least one person has had the same issue as I, and most likely there are multiple solutions...

Is there a way to isolate my IOT device (i.e. google home, chromecast, nest cams, etc.) to a guest network but still be able to cast/access to them from my main network? what's the best solution? Put everything on a guest network??? I don't want to have to be switching networks to access...
