Advice needed on securing IOT
I am new to the forum, been an AV fan for as long as I can remember and a technology fan. Had been holding off from Smart appliances as was waiting for HomeKit to take off. Currently there isn't much HomeKit stuff that excites me, so I have jumped in with lots of Chinese stuf (Broadlink, Sonoff etc). What amazes me about these products (apart from the affordability) is the ease of installation and setup.
I want to secure my setup as much as possible, but am not sure what to do. I understand its a good idea to put all your IOT devices on the guest network, that makes sense as Guests dont have access to LAN, but I like to change the guest password frequently. Changing the password on each IOT device would take ages, also the apps to run the devices are on my phone, which is on the main network (not guest), so does that not defeat having the device on the guest network?
