Hi

I have a Deco M4R V2 mesh system setup in router mode. 

I have a whole lot of IOT devices like Shelly smart switches, sonoff switches, Xiaomi etc etc.

I read an article that said you should put your IOT devices on your guest network for an additional layer of security which is why i did it. 

For some reason now I cannot access the devices on the guest network remotely when i'm away from home. 

How do i resolve this? 

Do i need to a the devices to access the main netwok? Can i do that and how would i do that? 

when the shelly devices were on the main network I could ask Alexa to turn on certian devices however now it just says that it cannot find the devices. 

please can you help me?

Thanks Brett
