Smart Homes.
Smart Energy.
Smart Savings.
Control lighting, hot water, garage doors, gates, appliances and power usage from anywhere. Shelly smart devices allow you to automate your home, reduce wasted energy and gain complete visibility over how your home uses electricity.
Shelly Smart Devices can unlock a huge amount of control.
Shelly smart devices are compact smart relays and energy monitoring modules. In simple terms, they can be installed behind existing switches, near selected appliances, or in your switchboard to make normal electrical circuits smarter.
Start small
You can begin with just one or two lights, a garage door, a gate, or a single appliance. You do not need to automate the whole house at once.

Most homeowners are surprised by how many everyday electrical devices can be made smarter with Shelly relays. Start with a single project or automate multiple areas of your home over time. The beauty of Shelly is that you can start small and expand whenever you’re ready.
🏠 Smart Lighting
Add Shelly smart devices behing light switches and control lights remotely, create schedules, set scenes and automate indoor or outdoor lighting. Turn lights on before you arrive home or create security lighting schedules while you’re away.
🚪 Garage Doors
Open and close your garage door remotely, check if it has been left open and receive notifications if the door opens unexpectedly.
🚘 Automatic Gates
Add smart control to existing automatic gates. Open or close your gate from your phone and improve convenience and security.
🔥 Hot Water Cylinders
Add a Shelly smart devices such as the Power Pro meter or a Smart relay behind your hot water switch and monitor hot water energy usage and delay heating cycles during expensive peak power periods to potentially reduce running costs.
❄️ Heat Pumps
Monitor heat pump power consumption and understand exactly how much it costs to heat or cool your home throughout the year.
⚡ Energy Monitoring
See live household power usage, monitor selected circuits and identify where your electricity is being used so you can make smarter decisions.
See what your home is using in real time.
By adding a Shelly Pro EM or Shelly Pro 3EM meter to your switchboard, you can see live power usage and build a history of how your home uses electricity. This gives you real data instead of guessing where the power bill is going.
- View live power usage from your phone or computer.
- Track historical energy use and spot high-consumption periods.
- Monitor selected circuits such as hot water, heat pumps or high-use appliances.
- Use the information to make smarter decisions around peak usage and running costs.

Real smart home ideas that actually make sense.
Most people do not realise what can be done with shelly Smart devices. These are practical examples of how Shelly smart devices can be used around a home, garage, workshop or small business.
Smart garage door control
Add a Shelly relay to your garage door opener so you can remotely open or close the door from your phone. Add a wireless door sensor and you can also see whether the door is open, closed or partly open.
Door alerts when you are asleep or away
Create scenes such as: if the garage door opens between 10pm and 5am, send an alarm notification to your phone. When travelling, you could set a 24-hour alert so you know immediately if the door opens.
Monitor selected appliances
A Shelly relay can be installed near certain appliances to monitor power usage and allow remote switching. This is useful for understanding what an appliance costs to run, or turning it off when it is not needed.
Make non-smart devices smart
Auto gates, garage doors, selected lights, security equipment and other suitable circuits can often be made smarter with the right relay and setup. You keep the equipment you already have but add modern control.
Stop your hot water running at the worst time of day.
One powerful use is monitoring your hot water circuit and controlling when it runs. By using a spare CT on an energy meter and a suitable relay, your hot water cylinder can be managed so it avoids peak power usage periods where possible.
- Monitor how much power your hot water circuit uses.
- Control hot water heating around peak usage hours.
- Use real energy data to understand where savings may be possible.
- Link this setup with your wider smart home or energy-saving strategy.

Can CO Electrical install and configure Shelly devices?
Absolutely. We can supply, install, configure and help you get the most out of your Shelly smart home system.
Start with one or two lights and build from there.
A Shelly relay can be installed behind selected existing light switches to make that lighting circuit smart. You can still use the wall switch normally, while also adding phone control, scheduling and automation scenes.
Remote control
Turn selected lights on or off from your phone, whether you are home, at work or away.
Lighting controlTime scheduling
Set lights to turn on in the evening, turn off overnight, or run on a schedule while you are away.
Set and forgetScenes and automation
Create scenes for security, convenience, night lighting, outdoor lighting, garages or workshops.
The sky is the limitFind out what your heat pump is actually costing to run.
If your heat pump does not have built-in energy monitoring, a smart monitoring device can help show how much power it is using. This can be useful for understanding running costs, comparing heating habits, and spotting unusual power use.
- Monitor heat pump power usage over time.
- Compare usage through different seasons.
- See the effect of temperature settings and run times.
- Build smarter habits around comfort and efficiency.
Want to make one part of your home smart?
You do not need to start with a full smart home system. Start with a garage door, a couple of lights, hot water control, appliance monitoring or switchboard energy monitoring — then build from there.
