Should you install low

June 8, 2023 by Kevin C. Tofel 5 Comments

On a recent Internet of Things podcast episode, we took a voicemail question left on our podcast hotline. The caller is doing a home renovation and will have access inside the walls. He's trying to plan ahead for his smart home and wants to know what he should do from a low-voltage and high-voltage wiring standpoint. From a future growth standpoint, he's also interested in planning his network.

The latter part of that question has a shorter answer, so I’ll start with this one. If you have access to add wiring throughout a home, I’d definitely recommend running at least CAT-6 cables. And I’d aim for at least one ethernet port for bedroom or living area. This will allow wired transfer speeds at up to 1 Gb per second. A nice upgrade would be to use CAT-7 cables for a massive 10 GBps throughput boost.

And I’d supplement that network cabling with WiFi 6E mesh routers for wireless access. Make sure you realize that expected mesh Wi-Fi coverage areas are typically optimistic. Every home is designed and built with different materials that can adversely affect your wireless network coverage. Most mesh Wi-Fi routers don't yet support wired speeds above 2.5 Gbps either, although that's likely to change in the next few years.

Now on to the low-voltage wiring question. These days, there's really less need to have low-voltage wires throughout the smart home. I’ve actually never used a low-voltage product in the decade-plus time of having a smart home. Stacey has for some very specific use cases, such as home audio speakers and large automated shades.

Aside from any professional audio/visual scenarios or very large shades, there's little use for low-voltage systems in the smart home. Stacey notes that she spoke with some industry contacts at a recent IoT event and those who used to push for and support low-voltage solutions simply aren't.

Part of this is because you need a very specific product type to use it. And part of it is because of the proprietary nature of most low-voltage smart home solutions. Given that the Matter standard is rolling out (maybe not as fast as I might like), the more universal approach of Matter is where the industry is headed. And there aren't any low-voltage Matter devices available today. So unless you have a very specific product need that requires low-voltage wiring, we say skip it in your 2023 smart home.
