Random question,

I have some cheapo smart lights that are connected to a wireless access point (TP-Link AC1200 C50) which is connected to the internet via ethernet to my router that deals with the fibre to the house connection.

I have set up a guest wifi network on the access point due to paranoia about cheap smart lights, and have enabled network isolation so that the smart lights cannot connect to anything else connected to the access point. However, as all of the traffic has to route from the access point to the router then to the wider interwebs, is this in itself enough to stop any security issues that might arise from dodgy backdoors or anything like that? I would have thought that as the smartlights are on a isolated guest network they would never see any of the packets/data that is going to/from any other device in the house?

Thanks in advance!
