I have a bunch of IoT switches connected to my Wi-Fi.
I am aware of three possibilities to connect and control them.
- Through the Wi-Fi directly (like Samsung SmartThings does)
- Connect them to a personal VLAN and use them (seems more secure).
- Connect all the devices to a Raspberry Pi (or something similar) like a master and connect the devices to it.
Which one would be safest(most secure for iot) comparatively? Are there any better solutions, and how difficult would each one be?
