Smart Home Wiring: What You Need Before Installing Automation Devices

The smart home revolution is here—and growing fast. Whether you're interested in voice-controlled lighting, smart thermostats, app-based security, or automated blinds, today's connected devices offer convenience, efficiency, and peace of mind. But before you buy that next-generation smart gadget, there's one critical question to ask:

Is your home's electrical system ready for automation?

At Ebert Electric, we help homeowners across New London and Northeast Wisconsin plan and install the infrastructure that powers modern smart homes. In this article, we’ll walk you through what you need to consider—and what you might need to upgrade—before jumping into smart home technology.

Why Wiring Matters in a Smart Home

Most smart devices still rely on your home’s existing wiring to function safely and reliably. While some automation systems are wireless or battery-powered, many require hardwired connections, consistent voltage, or dedicated circuits to operate properly—especially when integrated into lighting, HVAC, or home security systems.

In older homes, especially those built before the 1990s, outdated wiring can lead to unreliable performance, connectivity issues, or even safety hazards. If your wiring can’t support the load, or if key components like your panel or switches aren’t compatible, your smart home experience may be frustrating rather than futuristic.

Key Electrical Considerations Before Installing Smart Devices

Neutral Wires at Every Switch

Many smart switches require a neutral wire to function. Neutral wires carry electricity back to the panel and help complete the circuit, but not all homes have them—especially in older constructions. Without them, your smart switches may not work at all.

Sufficient Wi-Fi Coverage & Power

Smart devices may connect wirelessly, but their hubs, bridges, and some wired elements still need stable power and signal. You may need to add power outlets, relocate equipment, or run CAT6 wiring to support a whole-home system.

Updated Electrical Panel

If your panel is outdated or maxed out, you may not have room to support the added load from smart thermostats, security systems, EV chargers, and connected appliances. Upgrading your panel now can future-proof your home for ongoing automation.

Grounding and Surge Protection

Smart devices are sensitive to voltage spikes. Proper grounding and whole-home surge protection are essential to protect your tech investment—especially during Wisconsin’s stormy seasons.

Dedicated Circuits for High-Load Devices

Video doorbells, home theaters, and smart HVAC systems may need isolated circuits to prevent overloads and ensure consistent performance. This is especially true if you’re layering multiple devices across one system.

Common Smart Devices That May Require Electrical Prep

• Smart switches and dimmers
• Automated blinds or motorized shades
• Smart outlets and receptacles
• Wired security cameras
• Smart thermostats
• Smart doorbells
• Home assistant hubs or panels
• EV chargers and energy monitors

Each of these has different electrical requirements, and it’s far easier to prepare your home now than retrofit later.

Why Professional Wiring Makes a Difference

Smart homes are only as smart as the systems that support them. At Ebert Electric, we specialize in wiring new homes for automation or upgrading existing systems to support connected living. Our licensed electricians ensure that smart-ready devices are correctly powered and safely installed, your home meets local and national electrical codes, and you avoid the common issues that come with DIY setups or incompatible wiring.

We also work with builders, remodelers, and tech installers across Northeast Wisconsin to coordinate seamless smart home upgrades.

Ready to Upgrade? Start with an Electrical Evaluation

Whether you're planning a full smart home conversion or just starting with a few key devices, it pays to get the wiring right from the beginning. We’ll assess your current system, identify what upgrades (if any) you need, and design a wiring plan that supports your smart home goals.
