The smart home industry is still in the early stages of development. There is not a smart home component design strategies plan in place. Many companies are developing components that will fit into a larger system however right now they are just components. They will be upgraded many times, there will be new devices added and gradually standards will be developed so that you can connect one companies devices to another companies devices and systems. But right now, it really is a confusing mess out there and also expensive.
What should a consumer do in a situation like this one especially if you are the early adopter type of person? The answer is to develop your own strategy around a smart home. Focus on the things that you really want to automate and those that provide security functionality. These devices and components are not cheap so you will also need to factor in your budget for this project.
Next spend some time reviewing those companies that have a complete system that meets your requirements. There is no sense trying to mix and match at this time from several companies if you want them to all interact with each other. Finally assess the companies that are in it for the long haul, have a development strategy of their own and provide support to their customers.
If you do all of this you may have a chance of installing a smart home system that meets your needs. It can interact with a central controller and is evolvable as devices and systems develop further. For more energy saving ideas, click here.
