Home Automation Retrofitting
Culture Electrical specialises in retrofitting home automation into existing Byron Bay and Northern Rivers homes — without ripping walls open or replacing every switch. We design and install smart home setups built around open platforms like Home Assistant, paired with hidden Shelly relay modules behind your existing switches and outlets. The result is a fully app-controlled, voice-controlled, schedule-driven home that runs locally on your network — no cloud lock-in, no monthly fees, no manufacturer ecosystem trap.
Home Assistant Installation & Setup
Home Assistant is the leading open-source home automation platform — fast, private, vendor-neutral, and free. We install Home Assistant on a Raspberry Pi, mini PC, or dedicated NUC depending on the size of your setup, configure your network for reliable Zigbee, Z-Wave, and Wi-Fi device discovery, set up secure remote access, and integrate every smart device you already own. We also build out custom dashboards, automations, scenes, and Google Home or Apple HomeKit bridging so the system feels effortless from day one.
Shelly Smart Switch & Relay Retrofits
Shelly relay modules sit hidden inside your existing wall switches, GPOs, and light fittings — meaning you keep your current switches, plates, and aesthetic while gaining full smart control. We retrofit Shelly 1, 1PM, 2PM, Plus, and Pro modules across lighting circuits, GPOs, hot water systems, pool pumps, and air conditioning. As licensed electricians we handle the live wiring safely and to AS/NZS 3000, which is exactly what Shelly's Australian installation requirements demand.
Smart Lighting, Scenes & Energy Monitoring
We design smart lighting layouts using Shelly dimmers, smart switches, Zigbee bulbs, or hardwired LED drivers depending on your needs. We can set up motion-triggered hallway lighting, sunrise wake-up scenes, holiday presence simulation, and circuit-level energy monitoring so you know exactly what's drawing power. We also integrate solar inverters (Fronius, Sungrow, Tesla Powerwall), EV chargers (Zappi, Tesla Wall Connector), and hot water systems for solar-aware load shifting that saves real money.

Frequently Asked Questions
Do I need to rewire my house to add smart switches?
No. Shelly relay modules and similar devices fit behind your existing switches and outlets, using the wiring already in place. In most Byron Bay and Northern Rivers homes that have a neutral wire at the switch, we can retrofit smart control room by room without any wall damage.
Why Home Assistant instead of Google Home or Apple HomeKit?
Home Assistant runs locally on your own network, so it keeps working if your internet drops, has no subscription, supports every major device protocol, and isn't tied to one manufacturer. It also bridges to Google Home and Apple HomeKit if you want voice control through those ecosystems.
Can you integrate solar, batteries, or EV chargers?
Yes. We integrate Tesla Powerwall, Fronius, Sungrow, and other solar inverters into Home Assistant for live monitoring and solar-aware automations — like running the pool pump or hot water heater only when solar is producing. We also integrate Zappi, Tesla Wall Connector, and other EV chargers.
Is it safe to install smart relays in the wall myself?
No — and in NSW it's illegal. Devices like Shelly relays carry mains voltage and must be installed by a licensed electrician to AS/NZS 3000. Culture Electrical holds NSW Electrical Contractor Licence 475547c. DIY installation can void your home insurance and put your family at serious risk.
