By implementing the right strategies, you can lower your energy bills, while enjoying the benefits of modern technology. However, it’s important to pay attention to how much you spend on smart gadgets to ensure a financial benefit in the end.
Smart Devices Relevant to Energy Savings
Let’s have a quick overview of the smart devices that can be used in a home automation system and can contribute to lower energy consumption.
Motion sensors and presence sensors are the first step and very useful in general in a smart home setup. More advanced solutions can identify specific individuals, allowing for more personalized control.
Temperature sensors measure room temperature and humidity, enabling efficient heating and cooling adjustments to maintain comfort without wasting energy.
Energy monitoring systems and smart sockets help track energy consumption on circuits or specific devices, providing insights into usage patterns.
Smart lighting solutions, such as bulbs and switches, allow you to control the brightness, color, and temperature of your lights. They can be programmed to automatically turn off when rooms are unoccupied and offer convenience with automated control, enhancing room ambiance.
IR/RF controllers can control any device that uses a remote, such as air conditioners, televisions, and ceiling fans. These controllers are particularly useful for integrating older devices into your smart home without replacing them.
Smart thermostats replace traditional thermostats, offering additional functionality for heating and cooling control. Radiator valves can be installed individually, allowing independent temperature regulation for each room.
Smart relays can be installed in electrical boxes or your electrical panel to control related devices. These components can be part of a larger smart home system, enabling centralized control and automation.
What Affects Your Energy Savings Potential
With the equipment options outlined, let’s identify the variables that will affect how much energy you can save with your home automation system. It will depend heavily on your current habits and routines, as well as the existing equipment and systems in your home.
Consider the following questions:
Do you live in an apartment or a detached house? The energy requirements and infrastructure can be very different. Apartments are usually cheaper to heat and cool, but also offer more limited options for automation. The options become more limited if you rent instead of owning your home.
What type of heating do you use? Is it a natural gas system, heat pumps, or other electricity-powered devices? You can usually automate a natural gas or heat pump system with a central smart thermostat and smaller devices with smart sockets. Always make sure they are tested and rated to handle the power required from your devices.
Do you have a central boiler for your apartment building or your own? Having your own boiler gives you more control over how and when you use it, maximizing the potential for savings.
If you have a central building heating system, how is consumption measured? There is a difference if it is measured by the water flow to your radiators or by the total time your thermostat was on. In the first case, you can take advantage of smart radiator valves, but in the second case, they would not make much difference in your bills.
Do you have solar panels? By monitoring your solar power generation, you can turn on power-hungry devices when your solar panels are most efficient.
Does your electricity provider have different rates depending on the time of day? Are the rates predefined or dynamic? This also plays a role in determining when you should use your power-hungry devices.
Do you or family members often forget to turn off lights and TVs? Investing in smart lighting solutions might be worthwhile, especially if you don’t use only LED lights.
Do you adjust your thermostat or AC when you sleep or leave the house? If you already have a good habit of adjusting your devices yourself, then an automated solution will provide extra convenience by automating what you did, but it will not offer any extra savings.
It’s also important to consider that smart devices consume energy themselves. Some are directly powered, like the central hub or USB-powered sensors, and some use batteries. Battery-powered sensors also have a cost associated with replacing their batteries. To maximize efficiency, have a good plan for your smart home so that you can do the most with the least number of devices.
In summary, if you already follow good practices for minimizing your energy consumption manually, you will probably not see any monetary benefits by automating. The value of a home automation system in that case will be in convenience, peace of mind, and comfort.
Given that there are so many variables, it would not be possible to offer suggestions that apply to everyone or even calculate potential savings in numbers. However, I can offer tips for good practices, and general suggestions, so you can judge what is best to apply to your specific circumstances.

Tracking Your Energy Usage
The first step to making informed decisions about energy savings is monitoring your energy consumption. This helps you understand where significant usage occurs and identify areas for improvement. There are several ways to monitor your energy consumption:
Smart Electricity Meter: Many utility companies offer smart meters that provide real-time data on your energy usage. This can be a convenient way to track your consumption without additional hardware, if you can connect your meter to your home automation hub. Some companies might also offer these data through online services.
Dedicated Smart Sensors for Your Meter: If you are not able to connect directly to your meter, there are available devices that can either connect to or monitor your meter and provide the data to your home automation system.
Clamp Sensors: You can use connected current clamps to measure the electricity flowing through your main line or specific circuits. These devices will provide a general overview of your energy consumption.
Power Monitoring Smart Sockets: These sockets allow you to monitor the energy consumption of specific devices. They can also help you determine if a device is on or off, which is useful for automation purposes.
Power Monitoring Relays: There are different types of smart relays that can be installed either behind a wall switch or on your electrical cabinet. They offer monitoring as well as control options.
Be mindful of your safety when dealing with electricity. It’s best to have some devices installed by a qualified professional to ensure safe installation and operation.

Maximizing Your Savings Potential
While smart lights are often mentioned for energy savings, they have minimal potential to save money. LED light bulbs are highly efficient, and even frequent use might result in annual lighting expenses under $100. Although the savings from smart LED bulbs are minimal, they offer other benefits as well and will not increase your energy consumption.
The greatest potential for savings lies in heating, followed by air conditioning, televisions, and lighting. Cooking consumes significant energy, but there are limited ways to optimize it. In contrast, heating systems present a substantial opportunity for savings, especially if you have a completely autonomous system. Automating a per-room heating setup can be costly, but the potential for energy savings is considerable.
Effective Strategies for Energy Efficiency
Here are some practical tips to apply to your home automation system to help you optimize your energy usage:
Identify Your Family’s Comfortable Temperatures
Use temperature sensors in the areas where your family spends the most time to determine the temperatures at which they feel comfortable. For example, consider at what temperature you typically turn on the heating or when a fan is sufficient instead of using air conditioning. This will be useful in creating your automations.
Prioritize Heating People, Not Spaces
While maintaining a certain temperature throughout your home is important, focus more on having a comfortable temperature where your family spends most of their time. Temperature sensors are best utilized when placed close to where you sit. The temperature near your sofa is more important than that near your bookcase. Use the values from these sensors to control your heating system and ensure that the areas where you spend most of your time are comfortably heated.
Utilize Online Weather Services
Set up notifications to alert you when the outside temperature is more comfortable than inside. Take advantage of days with good weather by opening your windows to adjust the temperature, instead of relying on your heating and cooling systems. Additionally, set up an automation to turn off your heating or air conditioning when windows are open to prevent energy waste.
Thermostatic Valves
While a central smart thermostat is good for controlling the average temperature of your house, different rooms often require different temperatures. Install thermostatic valves on radiators in rooms that are not frequently used, allowing you to lower or turn off heating when those rooms are empty.
Be Mindful of the Sun
In the summer, program the blinds to close automatically to block out the sun and reduce heat. In the winter, open the blinds during the day to let in sunlight and close them at night to retain heat. This can have a significant impact on your heating and cooling costs.
Optimize Use of Your Lights
Install motion-triggered lights in hallways and other areas where you don’t need constant lighting. You can also lower the brightness of your lights to 80%. This change is rarely noticeable and will save some energy without sacrificing comfort.
Turn Off Everything When Leaving Home or Going to Sleep
Create an automation to turn off all devices and adjust the thermostat when you leave the house or go to sleep. This includes lights, TVs, air conditioning, and any other devices that are a hassle to deal with.
Notifications for Lower Rates
Set up notifications to alert you when electricity rates are lower, so you can run energy-intensive tasks like laundry during these times.
