If I have a guest network on my router and connect all Alexa plugs, echo devices, Alexa fire tv and lights to it, how do I deal with the issue of being able to airplay to my tv and things like playing from Spotify on to echo devices? My understanding is this requires the devices to be connected to the same wifi network as the device to work. As my other primary network is for all laptops, smart phones and things like that that I want separate.
