As discussed in the article above, the FBI has recommended that we keep our smart home devices on a separate network so that the bad security on your refrigerator doesn’t compromise your laptop.
Recently, there has been a spate of articles about security problems with Ring products, which only serves to illustrate the FBI’s concern: the security on a lot of our smart home products are crap.
I have my modem/router from the ISP set up as the IoT network. I have another WiFi router attached to the modem via Ethernet, which then creates a subnet with Ethernet and Wifi using different SSIDs.
- SmartThings Hub (ethernet)
- Philips Hue Hub (ethernet)
- Thermostat (WiFi)
- Smart washing machine (WiFi)
- Smart refrigerator (WiFi)
- 2x ArloQ cameras (WiFi)
- Chromecast device connected to stereo receiver (WiFi)
- Router for main network (Ethernet)
- Computers and laptops (ethernet and WiFi)
- Phones and Tablets (WiFi)
- Printer (Ethernet)
- Dish Hopper and Joey (satellite TV set top boxes) (Ethernet)
- Two smart TVs (Ethernet)
- Two Blu-Ray players (Ethernet)
- Smart speakers (1x Google Home Mini, 2x Sony LF-S50G) (WiFi)
- Stereo receiver for home theater (Ethernet)
- NAS (Ethernet)
- Secondary router broadcasting same SSID (Ethernet)
Let me try and explain my reasoning here, and I’m asking for advice on my setup regarding which devices are on which network.
Most of the TVs and home theater stuff is connected via Ethernet. I have left them on the “main” network because they need to be on the same network as computers and mobile devices for casting, and because they’re on Ethernet. I may be willing to set up multiple WiFi networks, but there’s no way I’m going to deal with having two separate Ethernet networks in my home. That’s more work than I’m willing to put in.
My main question is the smart speakers. While I do occasionally cast from one of the mobile devices to play music on the Sony smart speakers over WiFi, I could just as easily use verbal commands to play my music on a given speaker. What do you guys think? Should the smart speakers go on the IoT network, or remain on the “main” network where the laptops, computers, mobile devices, and home theater stuff is?
I invite comments about the rest of my network setup. Should I move all the home theater stuff to the “IoT” network with all the other smart home devices? I like the reliability of having those devices on Ethernet, but I could move them back to WiFi and put them on the “IoT” network if that would be a good idea. Of course, that would make casting a hassle, but I can work around that or forgo casting.
What do you think?
