Load shedding has become part of daily life in South Africa. For smart home owners, unplanned power cuts present a unique challenge — not just inconvenience, but the potential for automation systems, networks, and security equipment to go offline without warning. The good news is that with the right planning, your smart home can continue running seamlessly through any stage of load shedding.
Why Smart Homes Are Vulnerable to Power Cuts
A smart home automation system relies on a network of connected devices — your Control4 controller, network switches, Wi-Fi access points, cameras, intercoms, and smart devices. When Eskom cuts power, every one of these devices goes offline simultaneously, leaving your home without security monitoring, climate control, lighting scenes, or remote access.
Unlike a standard home where a power cut means lights go off, a smart home without backup can leave you unable to open gates, disarm alarms, or even control basic lighting. Planning backup power into the design from the outset is essential.
Backup Power Options for Smart Homes
1. UPS (Uninterruptible Power Supply)
A UPS is the most targeted solution for keeping your core smart home infrastructure online. At minimum, you want your Control4 controller, network switches, and Wi-Fi access points on a UPS. Even a modest UPS can keep these running for 4–8 hours, covering most load shedding stages comfortably.
2. Lithium Battery Backup (LiFePO4)
Lithium battery systems like the Freedom Won or Pylontech range offer much larger capacity and can power your entire home — or critical circuits — for extended periods. When paired with solar, these systems can make your home effectively load-shedding proof for most stages.
3. Generator Integration
For homes with generators, your smart home can be programmed to detect the transition between mains and generator power and automatically re-arm security, restore lighting scenes, and manage load-sensitive equipment. Control4 makes this seamless through automatic restart sequences.
4. Solar PV + Battery Systems
A fully integrated solar and battery solution — managed through your smart home controller — gives you the most comprehensive protection. Control4 integrates with leading inverter brands including Victron, SolarEdge, and Fronius, giving you real-time energy monitoring and intelligent load management from your single home app.
What to Keep on Backup Power
When designing your backup power strategy, prioritise the following:
- Control4 controller and processors
- Network switches and core router
- Wi-Fi access points (all of them)
- Security cameras and NVR/DVR
- Alarm panel and access control
- Gate and garage motors
- Intercoms and video doorbells
- Smart lighting dimmers and keypads
Load Shedding Automations to Set Up
Beyond hardware, smart programming can make the load shedding experience far less disruptive. Here are automations Intello Home regularly programs for clients:
- Auto-restore lighting scenes when power returns
- Trigger gate and garage motor checks on power restoration
- Send mobile push notifications when mains power is lost or restored
- Automatically switch to a 'backup mode' scene (lower brightness, essential loads only)
- Notify if battery backup drops below a set threshold
- Schedule the geyser to heat only when solar is producing (avoiding evening peak loads)
Planning Ahead: Build It In From the Start
The most cost-effective time to plan for load shedding is during the initial smart home design phase. When we design a Control4 system for a new build or major renovation, we allocate backup power circuits for all critical AV and automation equipment as a standard part of the electrical brief.
Retrofitting backup power to an existing smart home is possible but is always more expensive and disruptive. If you're planning a new smart home or upgrade, speak to us about incorporating backup power into the design from day one.
